B. THERMOPILE OUTPUT CHECK

(“B” Reading. Thermostat contacts OPEN - Main burner OFF.)

1.Thermopile system - 500 millivolts minimum. If the minimum millivolt reading is not obtainable, readjust thermopile for maximum millivolt output. If millivolt reading is still below minimum specified, replace thermopile.

C. THERMOSTAT RESISTANCE CHECK

(“C” Reading. Thermostat contacts CLOSED - Gas valve knob “ON”. Main burner should be ON.)

1.If the “C” reading drops more than 80 millivolts, the resistance in the system is excessive and must be reduced. To correct:

a.Clean and tighten thermostat leads and connections.

b.Shorten or replace theirmostat lead wires.

c.Cycle thermostat rapidly (manually turn dial) to clean contacts.

D. AUTOMATIC PILOT DROPOUT CHECK

1.Hold gas valve knob depressed in pilot position until maximum output is observed. Then extinguish pilot and observe meter.

2.Dropout of automatic pilot magnet (sound should be audible) should occur between 75 millivolts and 25 millivolts. If dropout occurs outside these limits, change the valve.

MILLIVOLT CONTROL VALVE

To check Resistance of the gas valve, connect one wire to the valve as shown.

1.Resistance between the THTP & TH terminals must be 11.5Ω±0.2Ω

2.Resistance between the THTP & TP terminals must be 10.0Ω±0.2Ω

If resistance is outside of specifications listed, the gas valve must be replaced.

BEFORE REPLACING THERMOPILE CHECK MILLIVOLT READINGS

THERMOPILE READINGS

With all wires connected, with the pilot on and burners off, the thermopile reading at the TP&THTP terminals should be ~500mv. With the burners on, the millvolt reading should be ~200mv.

WARNING AND OPERATING PLATES

All warning and operating plates on the Keating MIRACLEAN® Griddle should be in place at all times. If plates are damaged or lost, replace them immediately.
