Note: Heat reduces battery life. You can protect the receiver and extend battery life by mounting receiver in wall or other location outside the fireplace.

CHECKING SYSTEM OPERATION

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

		CONNECT	SWITCH OR	METER
CHECK		METER LEADS	THERMOSTAT	READING

	OUTPUT

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 175 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 175 milli-volts, 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, 500 milli-volts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
