YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.1 Functional Description
YSCFC Series Flatbottom gas fryers contain a welded steel frypot (mild steel) with heat-transfer
ducting on the frypot bottom for efficient heating of oil without scorching. A draft inducer draws air
over the burners for combustion. Air movement directs the combustion products back and forth
across the frypot bottom by means of a set of baffles, transferring the heat evenly. Cold air is
prevented from entering the combustion chamber and cooling the oil during the coasting cycle.
Flames originate from orifices in three tubular burners positioned beneath the frypot. The diameter
of the orifices differs for Natural (CE:G20/G25) and LP (CE:G31) gas as indicated in the table
below.

An electromechanical gas valve regulates gas flow to the manifold. YSCFC Series Flatbottom gas
fryers are equipped with a 24-volt valve system and an electronic ignition system (direct spark
ignition).
Electronic Ignition Configuration
In units configured for electronic ignition, an ignition module connects to an ignitor assembly. 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 time delay circuit and a coil that activates the gas valve. The ignitor
assembly consists of a spark plug and a flame sensor element.
At start-up the ON/OFF switch is placed in the "ON" position, supplying 115 VAC or 230 VAC,
according to system configuration, to the Thermatron interface board. The voltage is stepped down
via transformer to 24 VAC before entering the ignition module. If resistance in the temperature
probe indicates the temperature in the frypot is below 150°F (66°C), the current flows through a melt
cycle circuit where a switch alternately closes for approximately 4 seconds and opens for
approximately 20 seconds. If the temperature is 150°F (66°C) or above, the current flows through a
heat circuit, bypassing the timer switch. In either case, current is supplied to the other leg of the heat
relay coil, which then closes an electronic switch in the 24 VAC circuit to provide current to the
ignition module.
Circuitry in the ignition module sends 24 VAC current to the gas valve via a normally closed highlimit switch and a drain safety switch. Simultaneously, the module causes the ignitor to spark for up

to 11 seconds to light the burner flame. A flame sensor verifies that 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 interrupted, preventing the main valve from opening, and the ignition module
"locks out" until the power switch is turned "OFF", then back "ON".
A temperature 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
interrupt current flow through the heat relay. This in turn interrupts the 24 VAC to the ignition
module, resulting in closure of the gas valve.
Control Options
YSCFC Series Flatbottom gas fryers are equipped with Thermatron temperature controller. The
fryer is turned on and off by means of a rocker switch and the temperature is set by adjusting a
potentiometer. The Thermatron board is located in the wireway box behind the control panel, or in a
component box inside the cabinet (depending on fryer configuration).
The Thermatron temperature controller operates by comparing resistance between the potentiometer
setting and the temperature probe. If the resistance values don’t match, an on-board relay energizes,
sending voltage to the gas valve that supplies fuel to the burners. When the resistance values are
equal, the on-board relay de-energizes, interrupting voltage to the gas valve, which stops the fuel
flow.
Depending on the system configuration and destination, 115VAC controller boards are used.
Line voltage enters the interface
board at J1. The temperature controls
(potentiometer) are connected to
terminals 7, 8 and 9. The sensor
probe circuit is connected to
terminals 10 and 11. The high-limit

CHAPTER 1: SERVICE PROCEDURES
Safety Components
All YSCFC Series Flatbottom gas fryers are 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 flash point. The high-limit thermostat acts as a normally closed power switch
that opens when exposed to temperatures above 410°F [(210°C) - CE] to 450°F [(232°C) - Non-CE].
CE and non-CE high-limits are not interchangeable.
Frying systems with built-in filtration are equipped with drain microswitches that disable the fryer if
the drain valves are not completely closed. Opening a drain valve (i.e. filtering or draining the fryer)
automatically opens the reset switch circuit. The drain valve must be fully closed prior to resetting
the safety switch.
1.2 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 included with the fryer before
attempting to relocate a fryer for servicing.
NOTE: Perform the following only if the fryer cannot be serviced in its installed location. Some of
the following service procedures require the fryer to be connected to the gas and/or electrical supply.
1. Shut off the gas supply to the unit. Unplug the power cords. Remove any attached restraining
devices.
2. Disconnect the unit from the gas supply.
3. Relocate the fryer for service accessibility.
4. After servicing is complete, reconnect the unit to the gas supply, reattach restraining devices, and

1.5 Calibrating the Thermatron Temperature
Controller
1. Ensure the fryer ON/OFF switch is in the "OFF" position. Fill the
frypot to the proper oil-level line with cooking oil/shortening. If
solid shortening is used, ensure that the shortening is properly
packed and melted in the frypot before proceeding.
2. Place the fryer ON/OFF switch in the "ON" position. Set the Thermatron dial to 325°F (162°C).
3. Allow the oil/shortening to stabilize at setpoint temperature. This is evident when the burners
have cycled on and off several times.
4. Insert a thermometer or pyrometer into the frypot within ½ inch (1.25 cm) of the probe tip.
Ensure the tip of the thermometer/pyrometer does not touch the bottom or sides of the frypot.
5. If the temperature on the thermometer is
higher or lower than 325°F (162°C), the
dial is out of calibration.
6. Calibrate the dial by first loosening two
setscrews in the dial (arrows). After loosening
both setscrews, slowly turn the dial to match
the temperature reading of the thermometer.
Tighten each setscrew, ensuring the dial does
not move on the shaft during tightening.
7. Allow burners to cycle on and off several
times, then recheck oil temperature as
described in step #5. If the Thermatron
dial temperature matches the thermometer
temperature, the controller is calibrated.
If not, repeat step #7.

the top assembly (single fryers) or joiner
strips, flue caps, etc. (systems).
Ensure blower-housing insulation strip remains in
place after installing the new frypot (arrow).
1.7 Troubleshooting and Problem Isolation
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 encountered.
Problems you are likely to encounter with YSCFC Series Flatbottom fryers can be grouped into five
categories:
1. Ignition failures
2. Improper burner functioning
4. Filtration problems
5. Leakage
3. Improper temperature control
1-15
YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
The probable causes of each category are discussed in the following sections. Troubleshooting
guides are included in Section 1.8 to assist in identifying some of the more common problems.
1.7.1 Ignition Failures
Ignition failure occurs when the ignition module fails to sense a flame within the 11-second time
delay period and locks out. Turn the fryer off, locate and correct the problem, then turn fryer back
on to clear the module lock.
There are three primary reasons for ignition failure, listed in order of probability:
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 indicator is that an entire battery of fryers fails to light. Verify that the quick disconnect
hose is properly connected, the fryer is connected to power, the main gas supply valve is open, and
the circuit breaker for the fryer electrical supply is not tripped. Some fryers are equipped with a
fryer reset-switch that must be reset each time the fryer is turned off.
Problems Related to the Electronic Circuits
If gas and electrical power are supplied to the fryer, the next most likely cause of ignition failure is a
problem in the 24 VAC circuit of electronic ignition systems. If the fryer is equipped with a
filtration system, first verify that the drain valve is fully closed. (The valve is equipped with a
microswitch that must be closed for power to reach the gas valve. Often, although the valve handle
appears to be in the closed position, the microswitch is still open.) If the valve is fully closed, or the
fryer does not have a filtration system, refer to the troubleshooting guides in this chapter.
Problems Related to the Gas Valve
If the problem is not in the 24 VAC circuit, it is most likely in the gas valve itself, but before
replacing the gas valve, refer to the troubleshooting guides in this chapter.

YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.7.2 Improper Burner Functioning
With problems in this category, the burner ignites but exhibits abnormal characteristics such as
"popping", incomplete lighting of burner, fluctuating flame intensity, and flames "rolling" out of the
fryer.
"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
• Clogged burner orifices
• Clogged burners
• Inadequate make-up air
• Heat damage to the controller or ignition module
• An out-of-adjustment ignitor or broken ignition wire
• A defective ignition module
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 requirements listed in the Installation and Operation manual that came
with the fryer, and that the pressure remains constant throughout all hours of usage. Refer to
Adjusting Burner Manifold Pressure in Section 1.4 if burner manifold pressure is suspected of
being incorrect.
On systems equipped with electronic ignition, verify that the ignitor is properly adjusted (electrode
tip and ignitor positioned properly over middle burner).
Clogged burners and burner orifices are also likely causes of delayed ignition. Clogged burners are
indicated by uneven flame or partial flame on the burner face. Clogged orifices are indicated by no
flame.
Another cause of popping is an insufficient air supply or drafts. Check for "negative pressure"
conditions in the kitchen area. If air is flowing into the kitchen area, 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 most likely is with one of the electrical
components. Examine the ignition module for signs of melting/distortion and/or discoloration due to
excessive heat build-up in the fryer. (This condition usually indicates improper flue performance.).
1-17
YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
Also, examine the controller for the same conditions. A melted or distorted ignition module is
automatically suspect and should be replaced, but unless the condition causing excessive heat in the
fryer is corrected, the problem is likely to recur.
Next, ensure the ignition wire is connected properly at both ends and examine it for obvious signs of
damage. Again, if damage is due to excessive heat in the fryer, that problem must also be corrected.
DANGER
MAKE SURE YOU ARE HOLDING THE INSULATED HANDLE OF THE SCREWDRIVER
AND NOT THE BLADE. THE SPARKING CHARGE IS APPROXIMATELY 25,000
VOLTS.
Check for proper operation by disconnecting the wire from the ignitor, inserting the tip of a
screwdriver 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 11 seconds.
Fluctuating flame intensity is normally caused by either improper or fluctuating incoming gas
pressure, but may also be the result of variations in the kitchen atmosphere. Verify incoming gas
pressure 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 systems starting and
stopping during the day. As air conditioning/ventilation systems start and stop, the pressure in the
kitchen may change from positive or neutral to negative, or vice versa. Changes in airflow patterns
may affect flame intensity.
Flames "rolling" out of the fryer are usually an indication of negative pressure in the kitchen. Air is
being sucked out of the fryer 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
procedures in Section 1.4. An obstructed flue or a faulty blower, which prevents the fryer from
properly exhausting, may also be the cause.
Excessively noisy burners, especially with flames visible above the flue opening, may indicate that
the burner gas pressure is too high or the gas valve vent-tube is blocked (if applicable). If the gas
pressure is correct, and the vent-tube is unobstructed (if applicable), the gas valve regulator is
probably defective.
1-18
YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.7.3 Improper Temperature Control
Temperature control, including the melt cycle, is a function of several interrelated components, each
of which must operate correctly. The principal component is the temperature probe. Depending
upon the specific configuration of the fryer, other components may include the Thermatron board,
the controller itself, and the ignition module.
Improper temperature control problems can be categorized into melt cycle problems and failure to
control at setpoint.
Failure to Control at Setpoint
In fryers equipped with a Thermatron temperature controller, the problem may be that the
temperature probe is improperly positioned. Other causes may be the Thermatron board or the
potentiometer. Possible causes are that the potentiometer is out of calibration, or the temperature
probe or Thermatron board is defective. Refer to Section 1.5 for instructions on calibrating the
Thermatron temperature controller.
1.7.4 Filtration Problems
Whenever the complaint is "the pump is running, but no oil is being filtered", check the filter paper
or filter leaf (screen) connections and ensure they are properly connected. Ensure the filter paper or
filter leaf is not clogged with food debris or sediment and is properly assembled.
If the pump motor overheats, a circuit breaker in the filter circuit will trip and the motor will not start
until it is reset. If the pump motor does not start after pressing the circuit breaker, press the red reset
switch located on the rear of the motor. If the pump then starts, something caused the motor to
overheat. Maybe several frypots were filtered one after the other and the pump got hot. Letting the
motor 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 following reasons:
• Shortening was solidified in the filter leaf or filter lines.
• The operator attempted to filter unheated oil or shortening. Cold oil and shortening are thicker
and cause the pump motor to work harder and overheat.
If the motor runs but the pump does not, there is a blockage in the pump. An incorrectly assembled
filter leaf allows food particles and sediment to pass through the filter pan and into the pump. When
sediment enters the pump, the gears bind up causing the motor to overheat, tripping the thermal
overload. Particles large enough to clog the pump may indicate that the crumb tray is not being used,
and that the filter leaf is not properly assembled. Solidified shortening in the pump will produce the
same result.
1-19
YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
A pump seized by debris or hard shortening must be disassembled, cleaned and reassembled as
follows:
1. Disconnect power to the filter system.
2. Remove the front cover of the pump to access the gears inside, if the pump is accessible while
still inside the cabinet. If the front cover is not accessible, the pump must be removed from the
pump motor (remove input/output plumbing from the pump prior to removing pump). Remove
setscrews to disengage the pump from the motor.
3. Prior to reassembly, the inside housing must be clean and free of any sediment or debris. Failure
to completely clean the inside housing and ring gear will cause gear binding after reassembly.
4. During reassembly, partially install the housing bolts in a star pattern, leaving a ⅛-inch (3 mm)
gap between the cover and housing flanges. Ensure there is no shortening or oil in the filter pan,
and that the filter pan is disconnected. With the motor running slowly draw the cover in, evenly
tightening the housing bolts. When the cover is snug on the housing tighten all bolts to 15 inchlbs (1.7 Nm) ensuring that the pump is working correctly. Turn the motor off.
The electronics of the SUFF/UFF filtration system are simple and straightforward. Microswitches
attached to handles for each vat and wired in parallel provide the 24 VAC required to activate the
pump relay coil. When the handles are moved to the ON position, the activated pump relay coil pulls
the pump motor switch in, supplying power to the pump motor.
Filter systems equipped with oil-return heaters are wired into the 120 VAC source, which remains
energized as long as the unit is plugged in.

YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.7.5 Leakage
Frypot leaks are usually due to improperly sealed high-limit, temperature probe or oil-return and
drain fittings. When installed or replaced, each of these components must be sealed with Loctite
PST567 sealant or equivalent to prevent leakage. In very rare cases, a leak may develop along one
of the welded corners of the frypot. When this occurs, the frypot must be repaired or replaced.
Frypot locations (indicated by arrows) where potential leaks could occur.

1.8 Troubleshooting Guides
The following procedures must be performed by an ASA. They are provided as an aid to expedite
troubleshooting and repair of YSCFC Series frying systems.
1.8.1 Main Burner Malfunctions
PROBLEM CORRECTIVE ACTION
Main burner will not
come on even though
air blower is in
operation; no gas
pressure at main
burner.
Air blower is not
operating, although
power is present at the
fryer.
Main burner flames are
small and appear lazy;
Oil does not come up
to temperature quickly.
1. Check that the combination gas valve is ON.
2. Check high temperature safety switch. Replace if defective.
3. Check air prover switch. Ensure green prover light is on. If not,
check for 24 VAC going into and coming out of the air prover
switch.
1. Cooked product or other material may have fallen into the flue
and lodged in the blower wheel, preventing it from turning.
Clean out flue and blower wheel.
2. Blower motor may have overheated and shut off. This
condition will correct itself when motor cools (20 minutes). If
problems with blower overheating persist, call for service.
3. If fryer is equipped with a Thermatron controller, the
temperature probe or the controller board may be defective.
1. Check gas pressure at the pressure tap of the burner manifold.
Use a standard water-type U-gauge manometer. With the
burner in operation, the pressure should be about 4" W.C. on
natural and 11" W.C. on propane (LP) gases. If not, unscrew
the cover of the pressure regulator adjustment and turn the
adjusting screw clockwise to increase gas pressure (or
counterclockwise to decrease the pressure). Replace cover
and plug.
There are signs of
excessive frypot
temperature;
oil becomes
discolored quickly.
1. Check the frypot for excessive build up of debris.
2. Thermatron controller may be out of calibration. Re-calibrate
in accordance with instructions in Section 1.5.
3. Check gas pressure.
4. Oil of inferior quality or used too long. Replace with quality oil.

YSCFC SERIES FLATBOTTOM GAS FRYERS
CHAPTER 1: SERVICE PROCEDURES
1.8.2 Indicator Lights
The fryer’s indicator lights serve a diagnostic purpose. All lights are lit when the fryer is working
properly. The green light on the control panel will cycle on and off as the fryer calls for heat. Use
the following procedures to isolate problems indicated by light combinations.
Turn the temperature dial to 400°F (204°C) to ensure the sensor will demand heat. Check all
indicator lights in the fryer cabinet and on the control panel. [Older units may have power and reset
switches with different colored lights (orange, amber, red, green, white.). Common Cabinet units
have a white power light and a green air prover light. Substitute the light color of the correct color
switch with the respective "green light" switch in the following troubleshooting procedures. The
control panel light colors haven’t changed.]
When turning the power switch "ON" and resetting the safety (reset) switch, check for the following:
LIGHT INDICATION PROBABLE CAUSE CORRECTIVE ACTION
GREEN LIGHT/POWER SWITCH IS
"ON"
GREEN LIGHT/SAFETY (RESET)
SWITCH IS "OFF"
GREEN LIGHT/CONTROL PANEL IS
