CHECKING SYSTEM OPERATION

The milli-volt system and individual components may be checked with a milli- volt meter having a 0-1000 mV range. Conduct each check shown in chart below by connection meter test leads to terminals as indicated.

		CONNECT	SWITCH OR
CHECK	TO	METER	THERMOSTAT	METER
TEST	TEST	LEADS TO	CONTACTS	READING
		TERMINALS		SHOULD BE

A.COMPLETE MILLI-VOLT SYSTEM CHECK

(“A” Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main burner should turn ON)

a.If the reading is more than 100 milli-volts and the automatic valve still does not come on, replace the control.

b.If the closed circuit reading (“A” reading) is less than 100 millivolts, determine cause for low reading, proceed to Section B below.

B.Thermopile Output Reading Check

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

1. Check gas pressure to the unit. If gas pressure is within minimum and maximum on data plate, then check pilot voltage, 325 millivolts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
