module will not energize the second main valve, and the main burner will not light. The S8600F, which is used on natural gas fryers, will continue to spark as long as the fryer’s thermostat calls for heat or until the pilot lights.

The S8600H, which is used on propane fryers, provides 100 percent shutoff and safety lockout. Its ignition sparks only for a pre-set length of time (15 or 90 seconds, as stamped on the module). If the pilot does not light within the timed trial for ignition period, the module goes into safety lockout, de-energizing the first main valve operator, closing the first main pilot valve in the gas control, and stopping the flow of gas to the pilot. You must then set the fryer’s thermostat below 200°F/93°C, move the on/off switch to OFF, and wait at least one minute before trying again to light the pilot.

2.Set the fryer’s thermostat above 200°F/93°C.

Watch to see whether there is a spark at the pilot burner immediately.

3.Time the spark from the time it starts to the time it shuts off.

4.Compare this time with the shutoff time that is stamped on the module. They should be the same.

5.Open the manual gas cock and make sure that no gas is flowing to the pilot or main burner.

6.Set the fryer’s thermostat below 200°F/93°C and wait at least one minute before continuing.

Main Burner Operation

When the pilot flame is established, a flame rectification circuit is completed between the sensor and the burner ground. The flame sensing circuit in the module detects the flame current, shuts off the spark generator, and energizes the second main valve operator. The second main valve opens and gas flows to the main burner, where it is ignited by the pilot burner. On the S8600H, the safety lockout timer is held in the normal operating mode.

When the thermostat no longer calls for heat, both valve operators are de-energized, and both valves in the gas control close.

Step 3: Reset the Module

1.Turn the thermostat to its lowest setting.

2.Wait at least one minute.

Step 4: Check Safety Shutoff

Operation

This step applies only to the S8600H, which is used on propane fryers.

1.Turn the gas supply off.
