ELECTRICAL WIRING (MILLIVOLT)
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.

The millivolt system and individual
components may be checked with
a millivolt meter having a 0-1000

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.
