ELECTRICAL WIRING (MILLIVOLT)

CONNECTING OPTIONAL REMOTE RECEIVER

FOLLOW INSTRUCTIONS SUPPLIED WITH THE REMOTE.

1.Connect the wires to the two .25" male connectors located on the left side of the valve when facing the unit (See Figure 16, page 19). Do not let wire touch grate or burner.

2.Stick velcro pads with self-adhesive backing to the right side of remote receiver and to the left side of the unit. See Figure 17.

3.Attach remote receiver with velcro pads. Control switch must face forward.

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

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

CHECK		CONNECT	ON/OFF	METER READING
	TO TEST	METER LEADS
TEST			CONTACTS	SHOULD BE
		TO TERMINALS
A	COMPLETE	2 & 3	CLOSED	MINIMUM 175mV
	SYSTEM
B	THERMOPILE	1 & 2	OPEN	MINIMUM 500mV
	OUTPUT

A.COMPLETE MILLIVOLT SYSTEM CHECK

(“A” Reading - On/Off Switch contacts CLOSED - Control Knob “ON” - Main burner should come ON)

a.If the reading is more than 175 millivolts and the automatic valve still does not come on, replace the control.

b.If the closed circuit reading (“A” reading) is less than 175 millivolts, determine cause for low reading, proceed to Section B below.

B.Thermopile Output Reading Check

(“B” Reading - On/Off Switch 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 millivolts minimum. If the minimum millivolt reading is not obtainable, replace pilot.
