A. COMPLETE MILLIVOLT SYSTEM CHECK
(“A” Reading - Thermostat contacts CLOSED - Control Knob “ON” - Main burner should be come 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.

THESE INSTRUCTIONS SUPERCEDE THE SECTION ENTITLED “HEARTH MOUNT” IN THE MILLI-VOLT
HAND-HELD REMOTE INSTRUCTIONS SUPPLIED WITH THE REMOTE.
1. Cut cable to length (approximately 12") for placement in the fire-
place.
2. Strip back
1
/4" of the insulation from both ends of each wire.
3. Connect two .25 female connectors to the wires at one end of the
cable.
4. Insert the opposite ends of the wires into the receiver wire terminals
and tighten the screws.
5. Connect the connectors to the two .25" male connectors located on
the left side when facing the unit (See Figure 19, page 21). Do not let
wire touch grate or burner.
6. Remove the hearthmount coverplate on the remote receiver. (Battery
pack must be temporarily removed prior to removing the cover plate).
Stick velcro pads with self-adhesive backing to top of remote receiver
and to the underside of the unit. Refer to Figure 20.
7. Attach remote receiver with velcro pads.
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 com-
ponents may be checked with a millivolt
meter having a 0-1000 mV range. Conduct
each check shown in chart below by con-
nection meter test leads to terminals as in-
dicated.
