1.7 Functional Description
FQG60T Series gas fryers contain a welded stainless steel frypot heated by gas flames diffused evenly through tubes
built into the frypot.
Flames originate from orifices in a burner manifold positioned beneath cast-steel burners. The burners are
positioned in the tube openings at the front of the frypot. The diameter of the orifices differs for natural and LP gas
as indicated in the accompanying table.

An electromechanical gas valve regulates gas flow to the manifold. FQG60T series gas fryers are equipped with a
24V ignition system.
1.8 Ignition System
The ignition module located inside the control box performs three important functions: It provides an ignition spark,
supplies voltage to the gas valve, and proofs the pilot flame.
The module contains a 90-second time delay circuit and a coil that activates the gas valve. The ignitor assembly
consists of a spark plug, a pilot, and a flame sensor element.
At start-up, the power switch on the touchscreen controller is placed in the ON position, supplying approximately 24
VAC to the heat-control circuitry in the Smart Interface Board and to one side of the heat relay coils on the Smart
Interface Board. If the resistance in the temperature probe indicates the temperature in the frypot is below 180ºF

1-7
(82ºC), the melt cycle function is activated where a timer activates for six seconds and deactivates for 24 seconds. If
the temperature is 180ºF (82ºC) or above, the melt cycle is bypassed. In either case, ground is supplied to the other
leg of the heat relay coils, which closes electronic switches 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 high-limit
switch and a float safety switch. Simultaneously, the module causes the ignitor to spark for up to 90 seconds to
light the pilot flame. A flame sensor verifies that the pilot is lit by measuring the flow of microamps through the
flame. If the pilot 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
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 SIB board to cut off current flow through the heat relay. This in
turn cuts off the 24 VAC to the ignition module, causing the gas valve to close.
NOTE: Microamp readings on these black modules will move up and down as the module pulses on and off and
this is an indication that the module is functioning.
1.9 Thermostats
A temperature probe monitors the temperature in the frypot. The probe resistance varies directly with the
temperature. As the temperature rises, resistance increases at a rate of approximately 2 ohms for every 1°F
(approximately 3.7 ohms for every 1°C). 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 current to the ignition module, resulting in closure of the gas valve.
Circuitry in the controller monitors the probe resistance and controls burner firing when the resistance exceeds or
falls below the programmed temperature or setpoint.
The fryers are also equipped with a high-limit thermostat. If 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).

1.10 Smart Interface Board (SIB)
All fryers in this series have a smart interface board (SIB)
located in the component box behind the controller panel.
The SIB board provides a link between the controller and
the fryer’s individual components without requiring
excessive wiring and executes commands from one
central point.
K2 is a single-pole-double throw (SPDT) relay that supplies
24VAC to the ignition and gas valve circuits.The relays on
this board are soldered to the board. If a relay fails, the board must be replaced. K1 is a single-pole-double throw
(SPDT) relay that supplies voltage through the high limit and the optional air pressure switch.
The SIB LEDs (labeled LED1 through LED7) are arrayed around the board to assist in troubleshooting.
The chart on pages 1-9 illustrates current flow through the board, and the table at the top of page 1-10 identifies
frequently used test points.
NOTE: Refer to Section 1.17.1 for troubleshooting flowchart.

1.11 Accessing Fryers for Servicing
Before performing any maintenance on your Frymaster fryer, shut off the gas supply to the unit and disconnect the
fryer from the electrical power supply. Remove any attached restraining devices.
DANGER
Moving a fryer filled with oil may cause spilling or splattering of the hot liquid. Follow the Drain to
Pan instructions in Chapter 2 of the FQ4000 Controller Operation 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 and relocate the fryer for service accessibility.
3. After servicing is complete, reconnect the unit to the gas supply and turn on gas supply, reattach restraining
devices, and plug in the electrical cords.
1.12 Cleaning the Gas Valve Vent Tube
1. Set the fryer power switch and the gas valve to the OFF position.
2. Carefully unscrew the vent tube from the gas valve. NOTE: The vent tube may be straightened for ease of
removal.
3. Pass a piece of ordinary binding wire (.052-inch diameter) through the tube to remove any obstruction.
4. Remove the wire and blow through the tube to ensure it is clear.
5. Reinstall the tube and bend it so that the opening is pointing downward.
1.13 Checking the Burner Manifold Gas Pressure
1. On non-CE fryers only ensure that the gas valve knob is in the OFF position (see
Figure 1A).
2. Remove the pressure tap plug from the gas valve assembly (see Figure 1B).
3. Insert the fitting for a gas pressure-measuring device into the pressure tap
hole.
4. On non-CE fryers only, place the gas valve in the ON position
5. Place the fryer power switch in the ON position. When the burner has lit and
burned steadily for at least one minute, compare the gas pressure reading to
the pressure for the corresponding gas in the appropriate table on the
following page. The tables on the following page list the burner manifold gas
pressures for each of the gas types that can be used with this equipment.
6. To adjust the burner gas pressure, remove the cap from the gas valve

DANGER
When pressure-testing incoming gas supply lines, disconnect the fryer from the gas line if the test
pressure is ½" PSI [3.45 kPa (14 inches W.C.)] or greater to avoid damage to the fryer’s gas piping
and gas valve(s).
NOTE: External gas regulators are not normally required on this fryer. A safety control valve protects the fryer against
pressure fluctuations. If the incoming pressure is in excess of ½" PSI (3.45 kPa/35 mbar), a step-down regulator is
required.
1.14 Adjusting the Pilot Flame
1. Remove the cap from the pilot adjustment screw hole on the gas valve.
2. Using a small, flat-tipped screwdriver, turn the pilot adjusting screw counterclockwise to increase length of flame
or clockwise to decrease length of flame. Adjust to obtain a flame from 1 inch to 1½ inches long.
3. Reinstall the pilot adjustment screw cap.
