ELECTRICAL WIRING (MILLI-VOLT)

CONNECTING REMOTE RECEIVER

THESE INSTRUCTIONS SUPERCEDE THE SEC- TION ENTITLED “HEARTH MOUNT” IN THE MILLI-VOLT HAND-HELD REMOTE INSTRUC- TIONS SUPPLIED WITH THE REMOTE.

1.	Unscrew 2 (two) screws located on the side of the
	frame. Unscrew 1 (one) screw located on top of the
	frame. Remove metal plate (Figure 16).
2.	Cut cable to length (approximately 12") for place-
	ment in the fireplace.
3.	Strip back 1/4" of the insulation from both ends
	of each wire.
4.	Connect two .25 female connectors to the wires at
	one end of the cable.
5.	Insert the opposite ends of the wires into the receiver
	wire terminals and tighten the screws.

6. Connect the connectors to the two .25" male con-

nectors located on the right side when facing the

unit (Figure 16). Do not let the wire touch the

grate or burners.

7.Stick velcro pads with self-adhesive backing to top of remote receiver and to the underside of the unit.

8.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.

CHECKING SYSTEM OPERATION

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

A.COMPLETE MILLIVOLT 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 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, 500 millivolts minimum. If the minimum milli-volt reading is not obtainable, replace pilot.
