Computer Information
This equipment has been tested and found to comply with the limits for a Class A digital device,
pursuant to Part 15 of the FCC rules. While this device is a verified Class A device, it has been shown
to meet the Class B limits. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates,
uses and can radiate radio frequency energy and, if not installed and used in accordance with the
instruction manual, may cause harmful interference to radio communications. Operation of the
equipment in a residential area is likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
The user is cautioned that any changes or modifications not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
If necessary, the user should consult the dealer or an experienced radio and television technician for

CHAPTER 2: INSTALLATION INSTRUCTIONS
2.1
General Installation Requirements
NOTE: PROPER INSTALLATION IS ESSENTIAL FOR EFFICIENT, TROUBLE-FREE
OPERATION OF YOUR FRYER. ANY UNAUTHORIZED ALTERATIONS MADE TO THIS
EQUIPMENT WILL VOID THE FRYMASTER WARRANTY.
Upon arrival, inspect the fryer carefully for visible or concealed damage. (See Shipping Damage
Claim Procedure in Chapter 1.)
CLEARANCE AND VENTILATION
The fryer(s) must be installed with a 6” (150 mm) clearance at both sides and back when installed
adjacent to combustible construction; no clearance is required when installed adjacent to noncom-
bustible construction. A minimum of 24” (600 mm) clearance should be provided at the front of the
fryer.
One of the most important considerations of efficient fryer operation is ventilation. Make sure the
fryer is installed so that products of combustion are removed efficiently, and that the kitchen ventila-
tion system does not produce drafts that interfere with proper burner operation.
The fryer flue opening must not be placed close to the intake of the exhaust fan, and the fryer must
never have its flue extended in a “chimney” fashion. An extended flue will change the combustion
characteristics of the fryer, causing longer recovery time. It also frequently causes delayed ignition.
To provide the airflow necessary for good combustion and burner operation, the areas surrounding
the fryer front, sides, and rear must be kept clear and unobstructed.
Fryers must be installed in an area with an adequate air supply and adequate ventilation. Adequate
distances must be maintained from the flue outlet of the fryer to the lower edge of the ventilation
filter bank. Filters should be installed at an angle of 45º. Place a drip tray beneath the lowest edge of
the filter. For U.S. installation, NFPA standard No. 96 states, “A minimum distance of 18 in. (450
mm) should be maintained between the flue outlet and the lower edge of the grease filter.”
Frymaster recommends that the minimum distance be 24 in. (600 mm) from the flue outlet to the
bottom edge of the filter when the appliance consumes more than 120,000 BTU per hour.
For installations in the United States, information on construction and installation of ventilating
hoods can be found in the NFPA standard cited above. A copy of the standard may be obtained from
the National Fire Protection Association, Battery March Park, Quincy, MA 02269.
DANGER
Do not attach an apron drainboard to a single fryer. The fryer may become unstable,
tip over, and cause injury. The appliance area must be kept free and clear of com-
bustible material at all times.

NATIONAL CODE REQUIREMENTS
The type of gas for which the fryer is equipped is stamped on the data plate attached to the inside of
the fryer door. Connect a fryer stamped “NAT” only to natural gas, those stamped “PRO” only to
propane gas, and those stamped “MFG” only to manufactured gas.
Installation shall be made with a gas connector that complies with national and local codes, and,
where applicable, CE codes. Quick-disconnect devices, if used, shall likewise comply with national,
local, and, if applicable, CE codes.
ELECTRICAL GROUNDING REQUIREMENTS
All electrically operated appliances must be grounded in accordance with all applicable national and
local codes, and, where applicable, CE codes. A wiring diagram is located on the inside of the fryer
door. Refer to the rating plate on the inside of the fryer door for proper voltages.
DANGER
If this appliance is equipped with a three-prong (grounding) plug, it must be plugged
directly into a properly grounded receptacle.
Do not cut or remove the grounding prong from the plug.
DANGER
This equipment requires electrical power for operation.
Place the gas control valve in the OFF position in case of a prolonged power outage.
Do not attempt to use the equipment during a power outage.
FCC COMPLIANCE
The user is cautioned that any changes or modifications to Frymaster computers not expressly ap-
proved by the party responsible for compliance could void the user’s authority to operate the equip-
ment.
Frymaster computers have been tested and found to comply with the limits for a Class A digital de-
vice, pursuant to Part 15 of the FCC rules. While these devices are verified as Class A devices, they
have been shown to meet the Class B limits. These limits are designed to provide reasonable protec-
tion against harmful interference when the equipment is operated in a commercial environment. This
equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in
accordance with the instruction manual, may cause harmful interference to radio communications.
Operation of the equipment in a residential area is likely to cause harmful interference in which case
the user will be required to correct the interference at his own expense.
If necessary, the user should consult the dealer or an experienced radio and television technician for
additional suggestions.

ernment Printing Office, Washington, DC 20402, Stock No. 004-000-00345-4.
2.2
Caster/Leg Installation
Depending upon the specific configuration ordered, your fryer may have been shipped without in-
stalled casters or legs. If casters or legs are installed, you may skip this section and proceed to sec-
tion 2.3, Pre-Connection Preparations.
If your fryer requires the installation of casters/legs, install them in accordance with the in-
structions included in your accessory package.
2.3
Pre-Connection Preparations
DANGER
Do not connect fryer to gas supply before completing each step
in this section.
After the fryer has been positioned under the fry station exhaust hood, ensure the following has been
accomplished:
1. Adequate means must be provided to limit the movement of fryers without depending upon the
gas line connections. If a flexible gas hose is used, a restraining cable must be connected at all
times when the fryer is in use. The restraining cable and installation instructions are packed with
the flexible hose in the accessories box that was shipped with your unit.
2. Single unit fryers must be stabilized by installing restraining chains on fryers equipped with
casters or anchor straps on fryers equipped with legs. Follow the instructions shipped with the
casters/legs to properly install the chains or straps.
3. Level the fryer, if necessary, by loosening the locking screw on the caster legs and rotating the
leg to increase or decrease the exposed length. Verify that the fryer is at the proper height in the
exhaust hood. Frymaster recommends that the minimum distance from the flue outlet to the bot-
tom edge of the hood be 24 in. (600 mm) when the appliance consumes more than 120,000 BTU
per hour.
4. Test the fryer electrical system:
a. Plug the fryer electrical cord(s) into a grounded electrical receptacle.
b. Place the power switch in the ON position.
• For fryers equipped with thermostat controls, note the illumination of the power light and
the heat light.
• For fryers having computers, note that the display reads LO- TEMP and the heat light
comes on.
• If the store is equipped with a hood interlock system, the hood exhaust fan should be on.
If not, the store hood interlock system is improperly wired and must be corrected.

c. Place the fryer power switch in the OFF position. Verify that the power and heat lights are
out, or that the display shows “OFF”.
5. Refer to the data plate on the inside of the fryer door to determine if the fryer burner is config-
ured for the proper type of gas before connecting the fryer quick-disconnect device or piping
from the gas supply line.
6. Verify the minimum and maximum gas supply pressures for the type of gas to be used in accor-
dance with the accompanying tables.

The size of the gas line used for installation is very important. If the line is too small, the gas pres-
sure at the burner manifold will be low. This may cause slow recovery and delayed ignition. Fry-
master recommends the incoming gas supply line be a minimum of 1½” (38 mm) in diameter. Refer
to the chart on the following page for the minimum sizes of connection piping.

nection by one pipe size.
Before connecting new pipe to your unit, the pipe must be thoroughly blown out to remove any for-
eign particles. If these foreign particles get into the burner and controls, they will cause improper
and sometimes dangerous operation.
CE Standard
Required airflow for the combustion air supply is 2m3/h per kW.
1. Connect the quick-disconnect hose to the fryer quick-disconnect fitting under the front of the
fryer and to the building gas line.
NOTE: Some fryers are configured for a rigid connection to the gas supply line. These units are
connected to the gas supply line at the rear of the unit.
When using thread compound, use very small amounts on male threads only. Use a pipe thread
compound that is not affected by the chemical action of LP gases (Loctite™ PST56765 Sealant is
one such compound). DO NOT apply compound to the first two threads. This will ensure that
the burner orifices and control valve do not become clogged.
2. Open the gas supply to the fryer and check all piping, fittings, and gas connections for leaks. A
soap solution should be used for this purpose.
DANGER
Never use matches, candles, or any other ignition source to check for leaks.
If gas odors are detected, shut off the gas supply to the fryer
at the main shut-off valve and contact the local gas company or an authorized
service agency for service.
3. Close the fryer drain valve and fill the frypot with water and boil-out solution to the bottom OIL-
LEVEL line at the rear of the frypot. Light the fryer and perform the boil-out procedures that are
described in the “Lighting Instructions” and “Boiling Out the Frypot” topics found in Chapter 3
of this manual.

WARNING
“Dry-firing” your unit will cause damage to the frypot. Always ensure that melted
shortening, cooking oil, or water and boil-out solution is in the frypot before firing
your unit for any extended period.
4. It is suggested that the burner manifold pressure be checked at this time by the local gas company
or an authorized service agent. Refer to “Check Burner Manifold Pressure” on 3.4 of this manual
for the proper procedure. The accompanying tables list the burner manifold gas pressures for the
various gas types that can be used with this equipment.

Converting to Another Gas Type
Your fryer is configured at the factory for either natural gas or propane (LP) gas. If you desire to
switch from one type of gas to another, a gas conversion kit must be installed by a Factory
Authorized Service Center technician.
DANGER
Switching to a different type of gas without installing the proper conversion kit may
result in fire or explosion! NEVER attach your fryer to a gas supply for which it is
not configured.

H52 Series Fryers manufactured for Non-CE countries use different burners for each type gas. The
burners in fryers built for Propane gas have a special gray-colored coating on the burner tiles to en-
able them to withstand the higher caloric value of the Propane gas. Burners designed for use in Pro-
pane units may be used in natural gas applications, but not vice versa.

2.6
Frypot Boil-Out
Before the fryer is first used for cooking product, it should be boiled out to ensure that any residue
from the manufacturing process has been eliminated.
In addition, after the fryer has been in use for a period of time, a hard film of caramelized vegetable
oil will form on the inside of the frypot. This film should be periodically removed by following the
boil-out procedure.
Refer to Fryers Maintenance Requirement Card (MRC) 14A for the boil-out procedure.

CHAPTER 3: SERVICE PROCEDURES,
TROUBLESHOOTING AND WIRING DIAGRAMS
3.1
Functional Description
H52 Series fryers contain a welded stainless steel frypot that is directly heated by a high efficiency
infrared burner system requiring approximately 43% less energy than conventional burners to cook
the same volume.
Self-contained combustion chambers (referred to as “burners”) are fitted into rails attached to the
sides of the frypot, one on each side. Each combustion chamber is fitted with special ceramic tiles
that are heated by the burning of a forced air/gas mixture. The tiles transfer their heat to the frypot
by means of infrared radiation, providing much more constant and uniform heat dispersion over the
surface of the frypot than do conventional burners. Because relatively less heat is lost to the atmos-
phere in the process, compared to “open-burner” designs, less fuel is required to achieve and main-
tain a given frypot temperature.
In full-vat units, gas flow to both of the burners is regulated by one electromechanical gas valve. In
dual-vat units, each burner has its own valve. All fryers in this series are equipped with 24VAC gas
valve systems, and all are configured with electronic ignition.
THE ELECTRONIC IGNITION SYSTEM
An ignition module mounted in the component box or
Inside the Ignition Module
“shield” (located behind the control panel) is connected to
an ignitor assembly at the burner. The ignition module
performs three important functions: it provides an ignition

spark, supplies voltage to the gas valve, and proofs the

burner flame. The module contains a 4-second time delay
circuit and a coil that activates the gas valve. Three designs

are in use. The module used in Australian export units
Coil
resembles an interface board. A closed-box design is used
in units built for the U.S. and other export markets. Before
TD
mid-2001, fryers (other than Australian) were equipped
HV
with two 807-1006 modules. Fryers built after late 2000 to
GND
mid-2001 are equipped with two 807-3365 (dual vat) or one
807-3366 (full vat) module. Fryers built between late-2000
Ignition Wire
Flame Sensor
and mid-2001 may have either configuration. Australian
units continue to use two 807-2971 modules.
The ignitor assembly consists of a spark plug, an enrichment tube, and a flame sensor.
At start-up, the power switch is placed in the ON position, supplying approximately 12-volts DC to
the heat control circuitry in the controller or computer and to one side of the heat relay coils on the
interface board. If resistance in the temperature probe indicates the temperature in the frypot is
below 180ºF (82ºC), the current flows through a melt cycle circuit where a timer switch alternately
closes for 6 seconds and opens for 24 seconds. If the temperature is 180ºF (82ºC) or above, the
current flows through a heat circuit, bypassing the timer switch. In either case, ground is supplied to
the other leg of the heat relay coils, which then close electronic switches in the 24VAC circuit to

provide current to the ignition module. Circuitry in the ignition module sends 24VAC to the gas
valve via a normally closed high-limit switch (and, in BIH52 fryers, a normally closed drain safety
switch). Simultaneously, the module causes the ignitor to spark for 4 seconds to light the burner. A
flame sensor verifies the burner is lit by measuring the flow of microamps through the flame. If the
burner does not light (or is extinguished), current to the ignition module is cut, the gas valve closes,
and the ignition module “locks-out” until the power switch is turned off and then back on.
A probe monitors the temperature in the frypot. When the programmed setpoint temperature is
reached, resistance in the probe causes the heat cycle circuitry in the controller to cut off current flow
through the heat relay. This in turn cuts off the 24VAC to the ignition module, causing the gas valve
to close.
H52 Series fryers may be equipped with solid-state analog controls, M100B computers, or M2000
computers.
All fryers in this series have an interface board located in the component box located behind the
control panel.
INTERFACE BOARDS
The interface board provides a link between the controller/computer and the fryer’s individual com-
ponents without requiring excessive wiring, and allows the controller to execute commands from one
central point. The H52 Series of fryers has been in production since 1983. Consequently, servicers
are likely to encounter several different interface board designs. Although the boards differ in ap-
pearance, basic functioning and electrical connections are the same from one to another. In late-
2000, a new, unfused, ignition module design was introduced. Consequently, an additional fuse was
added to the design of interface board 806-3398 to compensate. The new, two-fuse board is P/N
106-0386. With the exception of manufactured gas units, no matter what generation board is in the
fryer now, if it becomes necessary to replace the board, either P/N 806-3398 or 106-0386 will be the
replacement part installed. If unit being serviced is equipped with two P/N 807-1006 or 807-2971
ignition modules, either interface board may be used. If the unit is equipped with one P/N 807-3365
or 807-3366 ignition module, interface board 106-0386 should be used. The two boards most likely
to be seen (i.e., the two latest designs) are illustrated below.

These standard interface boards are also used in a number of fryer types besides the H52 Series. The
information contained in this section applies to H52 Series applications ONLY.
The earlier design 806-3398 board contains two heat relays (K1 and K2) that switch 24VAC to the
ignition and gas valve circuits when the computer/controller heat logic circuit calls for heat. Relay
K4 switches 120VAC to the blower motor when either K1 or K2 closes. The relays on this board are
soldered on – if one fails, the whole board must be replaced.
The newer design 806-3398 and 106-0386 boards have one or two relays. In this design, K2 and K3
are double-pole-double throw (dpdt) relays that supply 24VAC to the ignition and gas valve circuits,
as well as 120VAC to the blower motor. The relays on this board plug into sockets. If a relay fails,
that relay can be replaced.
All three interface boards have LEDs to assist in troubleshooting. On the earlier design 806-3398
board, nine LEDs are arranged along the bottom. Later versions of the 806-3398 board, and the 106-
0386 board have seven LEDs placed at various locations. The tables below identify the LEDs and
their meaning.

THERMOSTATS
All fryers in the H52 Series have temperature probes located on the front centerline of each the fry-
pot. (Dual vat frypots have a probe in each vat.) In this type thermostat, the probe resistance varies
directly with the temperature. That is, as the temperature rises, so does resistance, at a rate of ap-
proximately 2 ohms for every 1º F. Circuitry in the controller monitors the probe resistance and
controls burner firing when the resistance exceeds or falls below programmed temperatures (set-
points). The temperatures are programmed by means of a keypad or knob on the face of the control-
ler.
H52 Series fryers are also equipped with a high-limit thermostat. In the event that the fryer fails to
properly control the oil temperature, the high-limit thermostat prevents the fryer from overheating to
the flash point. The high-limit thermostat acts as a normally closed power switch that opens when
exposed to temperatures above 425ºF to 450ºF (218ºC to 232ºC). The different types of thermostats
have different part numbers for CE and Non-CE configured models, and are not interchangeable.
3.2
Accessing Fryers for Servicing
DANGER
Moving a fryer filled with cooking oil/shortening may cause spilling or splattering of
the hot liquid. Follow the draining instructions in Chapter 4 of this manual before
attempting to relocate a fryer for servicing.
1. Shut off the gas supply to the unit. Unplug the power cords. Disconnect the unit from the gas
supply.
2. Remove any attached restraining devices.
3. Relocate the fryer for service accessibility.
4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and
plug in the electrical cords.
3.3
Cleaning the Gas Valve Vent Tube
NOTE: This procedure is not required for fryers configured for export to CE
countries.
1.
2.
Set the fryer power switch and the gas valve to the OFF position.
Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be
straightened for ease in removal.
3.
Pass a piece of ordinary binding wire (.052 inch diameter) through the tube to remove any
obstruction.

Measuring Flame Current
When the burner flame is properly adjusted, it will produce a current between 2.5 µA and 3.5 µA.
Flame current is measured by placing a microamp (not milliamp) meter in series with the sensing
wire on the ignitor. This is accomplished as follows:
1. Place the fryer power switch in the OFF position.
2. Disconnect the white sensing wire from one of the burner ignitors and connect it to the positive
lead of the meter. Connect the negative lead of the meter to the terminal from which the sensing
wire was removed.
3. Place the fryer power switch in the ON position to light the burners. After the frypot temperature
reaches 200°F (93°C), wait at least one minute before checking the reading. NOTE: The closer
the unit is to normal operating temperature, the more accurate the reading will be.

Troubleshooting and Problem Isolation
Because it is not feasible to attempt to include in this manual every conceivable problem or trouble
condition that might be encountered, this section is intended to provide technicians with a general
knowledge of the broad problem categories associated with this equipment, and the probable causes
of each. With this knowledge, the technician should be able to isolate and correct any problem en-
countered.
Problems you are likely to encounter can be grouped into six broad categories:
1. Ignition failures
2. Improper burner functioning
3-21
Download from Www.Somanuals.com. All Manuals Search And Download.
3. Improper temperature control
4. Computer-related problems
5. Filtration problems
6. Leakage problems
The probable causes of each category are discussed in the following sections. A series of Trouble-
shooting Guides (decision trees) is also included at the end of the chapter to assist in identifying
some of the more common problems.
3.7.1 Ignition Failures
Ignition failure occurs when the ignition module fails to sense a flame within the 4-second time delay
period and locks out. When this happens, the module sends 24VAC through the interface board
alarm circuit to the controller/computer.
Analog controllers indicate ignition failure by illuminating the heat light and trouble light simultane-
ously. M100B and M2000 computers flash “ig n it io n f a il u r e ” in the display window on the
side that failed (in full-vat units, it will flash in the right window only).
The three primary reasons for ignition failure, listed in order of probability, are:
1. Problems related to the gas and/or electrical power supplies
2. Problems related to the electronic circuits
3. Problems related to the gas valve.
PROBLEMS RELATED TO THE GAS AND/OR ELECTRICAL POWER SUPPLIES
The main indicators of this are that an entire battery of fryers fails to light and/or there are no indi-
cator lights illuminated on the fryer experiencing ignition failure. Verify that the quick disconnect
fitting is properly connected, the fryer is plugged in, the main gas supply valve is open, and the cir-
cuit breaker for the fryer electrical supply is not tripped.
PROBLEMS RELATED TO THE ELECTRONIC CIRCUITS
If gas and electrical power are being supplied to the fryer, the next most likely cause of ignition fail-
ure is a problem in the 24VAC circuit. If the fryer is equipped with a built-in filtration system
(BIH52 models), first verify that the drain valve is fully closed. (The valve is attached to a mi-
croswitch that must be closed for power to reach the gas valve. Often, although the valve handle ap-
pears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the
fryer does not have a built-in filtration system, refer to the troubleshooting guides TROUBLE-
SHOOTING THE 24VAC CIRCUIT.
Some typical causes of ignition failure in this category include a defective sensing wire in the ignitor
assembly, a defective module, a defective ignition wire, and a defective ignitor.
Occasionally you may encounter an ignition failure situation in which all components appear to be
serviceable and the microamp reading is within specification, but the unit nevertheless goes into
ignition failure during operation. The probable cause in this case is an intermittent failure of an
ignition module. When the unit is opened up for troubleshooting, the module cools down enough to
3-22
Download from Www.Somanuals.com. All Manuals Search And Download.
operate correctly, but when the unit is again closed up and placed back into service the module heats
up and fails.
PROBLEMS RELATED TO THE GAS VALVE
If the problem is not in the 24VAC circuit, it is most likely in the gas valve itself, but before replac-
ing the gas valve refer to TROUBLE SHOOTING THE GAS VALVE.
3.7.2 Improper Burner Functioning
With problems in this category, the burner ignites but exhibits abnormal characteristics such as
“popping,” dark spots on the burner ceramics, fluctuating flame intensity, and flames shooting out of
the flue.
“Popping” indicates delayed ignition. In this condition, the main gas valve is opening but the burner
is not immediately lighting. When ignition does take place, the excess gas “explodes” into flame,
rather than smoothly igniting.
The primary causes of popping are:
• Incorrect or fluctuating gas pressure
• A defective or incorrectly adjusted combustion air blower
• Inadequate make-up air
• Heat damage to the controller or ignition module
• A cracked ignitor or broken ignition wire
• A defective ignition module
• Cracked burner tile (this typically causes a very loud pop).
If popping occurs only during peak operating hours, the problem may be incorrect or fluctuating gas
pressure. Verify that the incoming gas pressure (pressure to the gas valve) is in accordance with the
appropriate CE or Non-CE Standard found in Section 2.3 of this manual, and that the pressure re-
mains constant throughout all hours of usage. Refer to page 2-6 for the procedure for checking the
pressure of gas supplied to the burner.
If popping is consistent during all hours of operation, the most likely cause is an insufficient air sup-
ply. Check for “negative pressure” conditions in the kitchen area. If air is flowing into the kitchen
area, this indicates that more air is being exhausted than is being replenished and the burners may be
starved for air.
If the fryer’s gas and air supplies are okay, the problem is most likely with one of the electrical com-
ponents. Examine the ignition module and controller for signs of melting/distortion and/or discol-
oration due to excessive heat build-up in the fryer. (This condition usually indicates improper flue
performance.) A melted or distorted ignition module is automatically suspect and should be re-
placed, but unless the condition causing excessive heat is corrected, the problem is likely to recur.
Verify that the ignition wire is tightly connected at both ends and free of obvious signs of damage.
Again, if damage is due to excessive heat in the fryer, that problem must also be corrected.

Check for proper operation by disconnecting the wire from the ignitor (spark plug), inserting the tip
of a screw driver into the terminal, and holding it near the frame of the fryer as the power switch is
placed in the ON position. A strong, blue spark should be generated for at least 4 seconds.
DANGER
MAKE SURE YOU ARE HOLDING THE INSULATED HANDLE OF THE SCREWDRIVER
AND NOT THE BLADE. THE SPARKING CHARGE IS APPROXIMATELY 25,000
VOLTS.
Examine the ignitor (spark plug) for any signs of cracking. A cracked ignitor must be replaced.
If all other causes have been ruled out, examine the burner tiles for any signs of cracking. If found,
the burner must be replaced.
Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas pres-
sure, but may also be the result of variations in the kitchen atmosphere. Verify incoming gas pres-
sure in the same way as for “popping,” discussed in the preceding paragraphs. Variations in the
kitchen atmosphere are usually caused by air conditioning and/or ventilation units starting and stop-
ping during the day. As they start and stop, the pressure in the kitchen may change from positive or
neutral to negative, or vice versa. They may also cause changes in airflow patterns that may affect
flame intensity.
Dark spots on the burner tiles are the result of an improper air/gas mixture. Adjust the combustion
air blower to reduce the amount of air in the mixture to correct this problem.
Flames shooting out of the flue are usually an indication of negative pressure in the kitchen. Air is
being sucked out of the burner enclosure and the flames are literally following the air. If negative
pressure is not the cause, check for high burner manifold gas pressure in accordance with the proce-
dures on page 2-6.
An excessively noisy burner, especially with flames visible above the flue opening, may indicate
that the gas pressure is too high, or it may be that, on non-CE units, the gas valve vent tube is
blocked. If the incoming gas pressure is correct and the vent tube on non-CE units is unobstructed,
the gas valve regulator is probably defective.
Occasionally a burner may apparently be operating correctly, but nevertheless the fryer has a slow
recovery rate (the length of time required for the fryer to increase the oil temperature from 270ºF to
320ºF (133ºC to 160ºC)). The primary causes of this are an over-filled vat, a dirty or out-of-
adjustment combustion air blower, low burner manifold pressure, and/or damaged burner tiles.
Adding oil to the frypot during the recovery process will also cause a slow recovery rate. If these
causes are ruled out, the probable cause is a misadjusted gas valve regulator. Refer to page 2-6 for
the procedure for checking the pressure of gas supplied to the burner.
3.7.3 Improper Temperature Control
Temperature control, including the melt cycle, is a function of several interrelated components, each
of which must operate correctly. The principle component is the temperature probe. Other compo-
nents include the interface board, the controller itself, and the ignition module.
3-24

Improper temperature control problems can be categorized into melt cycle problems and failure to
control at setpoint problems.
MELT CYCLE PROBLEMS
The melt cycle is automatically initiated by the controller (Analog, M100B, or M2000) when the
controller is first turned on. The unit should remain in the melt cycle until the oil in the frypot
reaches 180ºF (82ºC). (Do not confuse the melt cycle with the LOW TEMP warning. This warning will
be displayed when the M100B or M2000 computer senses that the oil in the frypot is more than 45ºF
(25ºC) below the setpoint.)
Problems may be with the controller itself, the temperature probe, or a malfunctioning heat relay on
the interface board.
FAILURE TO CONTROL AT SETPOINT
Problems in this category may be with the temperature probe, the interface board, or the controller.
3.7.4 Recovery Time or “Rate Of Rise” and the M100B “Rec Lock” Condition
Recovery time or “rate of rise” is a method of measuring a fryer’s performance. Put simply, it is the
time required for the cooking oil temperature to rise from 270ºF to 320ºF (133ºC to 160ºC). This
range is used as a standard since ambient kitchen temperatures can effect the test if lower ranges are
used.
The M100B computer performs the recovery test when the fryer is first turned on and anytime there-
after when the temperature of the oil drops below 250ºF (121ºC), such as when cold cooking oil is
added to the frypot. If the fryer takes longer than 2 minutes and 35 seconds to recover, the display
will show REC LOCK and the computer will lock out.
The currently recorded recovery time can be viewed anytime the temperature of the cooking oil is
above 270ºF (133ºC) by pressing the recovery time recall switch
.
If REC LOCK occurs three or more times within a week, verify that oil is not being added when the
fryer is heating (that is, while a heat mode indicator is illuminated). If oil is not being added while
the fryer is heating, there is a problem with the fryer.
To clear the REC LOCK condition, turn the computer off by pressing the right
switch. Enter the

3.7.5 Filtration Problems
BIH52 units are equipped with FootPrint III built-in filtration systems. The majority of filtration
problems arise from operator error. One of the most common errors is placing the filter paper on the
bottom of the filter pan rather than over the filter screen.
3-25

Whenever the complaint is “the pump is running, but no oil is being filtered,” check the installation
of the filter paper, including that the correct size is being used. While you are checking the filter pa-
per, verify that the O-ring on the bottom of the filter pan is present and in good condition. A missing
or worn O-ring will allow the pump to suck air and decrease its efficiency.
If the pump motor overheats, its thermal overload will trip and the motor will not start until it is re-
set. If the pump motor does not start, press the red reset switch located on the rear of the motor. If
the pump then starts, something caused the motor to overheat. It may just be that several frypots
were being filtered one after the other and the pump got hot. Letting the pump cool down for at least
a half-hour is all that is required in this case. More often, the pump overheated for one of the fol-
lowing reasons:
• Shortening was solidified in the pan or filter lines.
• The operator attempted to filter oil or shortening that was not heated. Cold oil and shortening
are thicker and cause the pump motor to work harder and overheat.
If the motor hums but the pump does not rotate, there is a blockage in the pump. Incorrectly sized or
installed paper will allow food particles and sediment to pass through the filter pan and into the
pump. When sediment enters the pump, the gears can bind up causing the motor to overload, again
tripping the thermal overload. Solidified shortening in the pump will also cause it to seize, with the
same result.
A pump seized by debris or hard shortening can usually be freed by manually moving the gears with
a screwdriver or other instrument as illustrated below. Make sure power to the pump motor is off
before trying this.
1. Disconnect power to the filter system.
2. Remove the input plumbing from the pump.
3. Use a screwdriver to manually turn the gears.
•
•
Turning the pump gears backwards will release a hard particle and allow its removal.
Turning the pump gears forward will push softer objects and solid shortening through the
pump and allow free movement of the gears.

Improperly sized or installed paper will also allow food particles and sediment to pass through and
clog the suction tube on the bottom of the filter carriage. Particles large enough to block the suction
tube may indicate that the crumb tray is not being used.
Pan blockage can also occur if shortening is left in the pan and allowed to solidify. The heater strip
on the suction tube is designed to prevent solidification of residual shortening left in the tube. It will
not melt or prevent solidification of shortening in the pan.
Blockage removal can be accomplished by forcing the item out with an auger or drain snake.
NEVER use compressed air or other pressurized gases to force out the blockage.
The electronics of the FootPrint III system are simple and straightforward. Microswitches, attached
to handles for each vat and wired in parallel, provide the 24VAC required to activate the pump relay
coil when the handles are moved to the ON position. The activated pump relay coil pulls in the
pump motor switch, supplying power to the pump motor.

FootPrint III Simplified Wiring Diagram
For FootPrint III systems built before August 1997, all heater tapes are wired directly into the line
VAC source. They remain energized as long as the unit is plugged in. In systems built in August
1997 and later, oil return line heater tapes have been eliminated. In these units, the only heater tape
used is on the suction tube and pump. This tape is still wired directly into the line voltage. A pair of
vacuum-breaking solenoids is wired into the 24VAC circuit.
The redesigned FP III is distinguished from original-design units by the absence of casters on the
filter base assembly. The redesign incorporated an improved oil return system that allows

for most heated oil return components.

when filter system is turned off, leaving no oil or
shortening in return lines.
Square Drain Sub-System
The only change to the square drain sub-system is the addition of a ¼” NPT vent coupling to the
leftmost end sections to allow attachment to a vacuum-breaking solenoid. The new end sections may
also be used on the original-design filtration system by plugging the vent port with a ¼” NPT pipe
plug coated with sealant. All other square drain components remain unchanged.
Rear-Flush Sub-System
A one-piece, welded rear manifold and Dormont stainless steel flexlines replace the various pieces of
½” NPT piping, flexlines, and heater-strips used on the original-design filtration system. A solenoid
vent valve is attached at the left end of the oil return manifold mounted at the rear of the leftmost two
frypots. It prevents vacuum-lock of the system as oil/shortening drains back to the filter pan when
the unit is turned off. The solenoid valve is connected to the square drain sub-system by a clear ⅜”
O.D. Teflon tube and threaded fittings. The Gemini ball valve used on the manifold is the same as
that used on the earlier design. Eight and one-half-inch stainless steel Dormont flexlines replace the
flexlines that connect the manifolds to the valves. Standard ½” X ½” X 90º black metal street el-
bows are used to make the connections.
Filter Base Assembly and Pump Sub-System
Casters are not present on the new-design filter base. In addition, the filter base assembly has been
redesigned to prevent it being taken out of the cabinet without removing a set of machine screws and
nuts. The filter pan is unchanged and is completely removable.
A new Teflon hose with a braided stainless steel covering connects the pump to the rear manifold
and replaces the heated hose running from the pump discharge under the unit to the Power Shower
plumbing. The new hose is fitted with a 90º swivel at the manifold end and a straight swivel at the
pump end to prevent kinking.
The pump plumbing has been changed by the addition of a solenoid valve at the pump discharge, a
¼” I.D. Dormont stainless steel flexline that connects the solenoid valve to the pump inlet fittings,

and miscellaneous standard black metal fittings for connections. This design allows oil/shortening to
bypass the pump as it drains from the oil return lines back into the filter pan when the system is
turned off. Bypassing the pump expedites draining of the lines. The pump solenoid leads are con-
nected to Pins 7 and 9 of the upper 9-pin plug assembly.
Filter Wiring Box
The original-design 5-lead cable connecting the filter assembly to the filter wiring box has been re-
placed with a new, universal 7-lead cable to accommodate the solenoid mounted on the front mani-
fold. The two new leads have a separate connector for attachment to the solenoid. When a filter ca-
ble is ordered for either filtration system configuration (original or redesigned), the new 7-wire cable
will be sent. The two extra wires and connector will not interfere with the original filtration system
or its operation.
Verifying Solenoid Operation
Proper operation of the 24VAC manifold and pump solenoids can be verified by removing the pump
motor lead from terminal 4 of the pump motor relay in the filter wiring box and then activating the
oil return lever. Proper solenoid operation will be evidenced by an audible “click” or vibration of
both the pump solenoid and the manifold solenoid.
3.7.6 Leakage Problems
Leakage of the frypot will usually be due to improperly sealed high limit thermostats, temperature
probes, and drain fittings. When installed or replaced, each of these components must be sealed with
Loctite® PST56765 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop
along one of the welded edges of the frypot. When this occurs, the frypot must be replaced.
If the sides and/or ends of the frypot are coated with oil/shortening, the most likely cause is spillage
over the top of the frypot rather than leakage.
The clamps, which hold the drain tube sections together, may loosen over time as the tubes expand
and contract with heating and cooling during use. If the section of drain tube connected to the drain
valve is removed for whatever reason, make sure that its o-ring is in good condition and properly
fitted around the nipple of the drain section when it is reinstalled. Also, check to insure that the
drain tube runs downward from the drain along its whole length and has no low points where oil or
shortening may accumulate.

NOTE: In September 1999, significant changes were made to the design of the filter base
assemblies used in BIH52 fryers. The most visible change was the removal of the casters on all
assemblies except 806-8804 (which is used in units manufactured for sale primarily in Japan). The
motor cover was also redesigned and a lower plumbing shield was added. Additionally, the two-
piece motor support (P/Ns 900-7469 and 900-7470) was replaced with a single, stronger support.
In order to provide continued support for units built prior to August 1999, a new filter base assembly
with casters (P/N 106-0043SP) was created to replace the original 806-5895 filter base assembly,
which is no longer available.
Two additional modifications to the design of the base sides have been made since August 1999.
These include the replacement of the die-cast metal handles with handles formed into the sides, and
the replacement of the separate lock brackets with brackets that are also formed into the sides.
