A Pilot Module

This appendix contains supplemental information about the Honeywell S8600 Intermittent Pilot Module. The Belshaw 718LCG, 724CG, and 734CG gas fryers all use this module. Fryers using natural gas use the S8600F-1000. Fryers using propane use the S8600H-1014.

WARNING

To avoid fire or explosion, resulting in property damage, injury, or loss of life, if you smell gas or suspect a gas leak, turn off the gas at the manual service valve and evacuate the building. Do not try to light any appliance or touch any electrical switch or telephone in the building until you are sure no spilled gas remains.

Step 1: Perform Visual

Inspection

1.Make sure the fryer’s on/off switch is in the OFF position. Make sure all wiring connections are clean and tight. If they are not, correct them.

2.Move the on/off switch to ON.

3.Open the manual shutoff valves in the gas line to the fryer.

4.If the piping has been disturbed, perform a gas leak test ahead of the gas control, as follows:

a.Paint the pipe joints with a rich solution of soap and water. Bubbles in the solution indicate gas leaks.

b.If there are leaks, tighten the joints.

c.Test again for leaks.

d.Repeat this procedure until no leaks exist.

Step 2: Review the Normal Operating Sequence

Figure A-1 summarizes this information.

WARNING

To avoid fire or explosion, resulting in property damage, injury, or loss of life, perform gas leak tests as explained in Steps 1 and 5 below at the time of initial installation and at any time work is done involving the gas piping.

Trial for Ignition

When the fryer’s thermostat calls for heat, the module energizes the first main valve operator. The first main valve opens, allowing gas to flow to the pilot burner. At the same time, the electronic spark generator in the module produces a spark pulse output of over 10,000 volts. The voltage generates a spark at the igniter-sensor that lights the pilot.

If the pilot does not light, or if the pilot flame current is not at least 1.0 μA and steady, the
