24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.1 Functional Description 24G 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.
The pilot flame must be manually lit when the fryer is first placed into operation. A separate circuit, activated by the fryer ON/OFF switch, provides voltage through the Thermatron temperature controller to the gas valve main coil, which opens the main valve.
Page 8
Control Options 24G 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.

24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES Not used MELT CYCLE DISABLE Thermatron Controller Board Line voltage enters the interface board at terminals 1 and 3. The temperature controls (potentiometer) are connected to terminals 7, 8 and 9. The sensor probe circuit is connected to terminals 10 and 11.
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.
4. Place the gas valve in the "ON" position then place the fryer power switch in the "ON" position. When the burner lights and continues to burn, note gas pressure reading for correct pressure in accordance with the table on page 1-1.
Pilot Ignition Valve (Line Voltage) 6. Place the fryer power switch and the gas valve in the "OFF" position. Remove the pressure- measuring device fitting from the pressure tap hole and reinstall the pressure tap plug. 1.5 Adjusting the Pilot Flame (where applicable) 1.

If not, repeat step #7. 9. After calibration is complete, place the fryer power switch in the "OFF" position and disconnect the fryer from the electrical supply. After Loosen two setscrews in dial (arrows) to recalibrate...
2. Allow the frypot to cool for 10 minutes before draining. Drain cooking oil/shortening from the frypot. Allow the frypot to cool completely before proceeding. 3. Remove the fryer door(s) for access to control panel screws. Lift door up, disengage rod from lower door bracket, and then remove door. (Current production models have spring-loaded door pins.
Page 15
24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 8. Remove the sensor bulb guard to access the probe and high-limit. Current production systems have a sensor bulb clamp that must be removed prior to removing the probe or high-limit from the frypot. 9.
1.7.2 Removing/Replacing Rocker Switches 1. Disconnect the fryer from the electrical supply. 2. If switches are located on front panel or control box, remove the screws securing panel. Do not allow the panel to hang on the switch wiring harness; use some type of support.
1.7.3 Replacing the Gas Valve Drain the frypot or remove drain valve handle to prevent accidental opening before Disconnect fryer from electrical and gas supplies. Disconnect the wires from the gas valve terminal block, marking each wire to facilitate reconnections. For 120VAC gas valves, disconnect the black wire from the high-limit, then remove the bombtail connecting the white wire.
Ensure ignitor is properly positioned (arrow) over the center burner prior to tightening the mounting screw. Multi-batteried systems after 02/03 have upper and lower back panels, which must be removed to access the blower assembly (fryer above shown with upper back panel removed). 1-13...

24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 2. Remove blower assembly by removing four screws (two screws securing the flue outlet to the firebox, and two screws securing the blower inlet housing to the firebox). Pull the assembly out of the slot and lower to the side.
If not, and no further service frypot/firebox required, reverse the above steps to reassemble the fryer. Inspect frypot baffles through burner tube opening (arrow) for signs of burn-through or damage. 1-15...

CHAPTER 1: SERVICE PROCEDURES 6. Remove two screws securing topcap to wireway box. Remove topcap. Remove four screws securing wireway box to fryer cabinet (arrows) and carefully lower wireway box out of the way. Use care not to stretch or distort the wiring.
Page 23
24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 10. Remove firebox back, insulation from back of frypot. From the rear of the unit, use a prying bar to carefully pry the top assembly from the frypot and cabinet frame (single units only), and set aside.
(arrow). Reverse the above steps to reassemble the fryer. Use high-temp silicone to re-install the top assembly (single fryers) or joiner strips, flue caps, etc. (systems). 1.8 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.
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 fryers equipped with electronic ignition systems, or in the pilot system for those without electronic ignition.
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.
Page 27
24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 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.
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.

24G 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.
24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.8.5 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.
24G SERIES FLATBOTTOM GAS FRYERS CHAPTER 1: SERVICE PROCEDURES 1.9 Troubleshooting Guides The following procedures must be performed by an ASA, and are provided as an aid to expedite troubleshooting and repair of 24G Series frying systems. 1.9.1 Pilot Burner Malfunctions PROBLEM Pilot will not ignite;...
(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.
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.

The ND90 filter option was discontinued in 1996 when the fryer design was changed to incorporate the Under Fryer Filter (UFF) system. A large number of ND90-equipped fryers were produced and Frymaster/Dean continues to support them with replacement systems and parts, with the exception that the “hands free” plumbing components are no longer available.
