Step 4. FIELD WIRING
Caution: Label all wires prior to disconnection
when servicing controls. Wiring errors can
cause improper and dangerous operation.
Verify proper operation after servicing.
Refer to Section A for millivolt appliances and
Section B for electronic appliances. The gas
valve is set in place and pre-wired at the factory
on both models.
A. Millivolt Wiring (See Figure 35) –
1. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed
in the control compartment. An optional
wall-mounted switch, wall thermostat, or
one of the optional remote control kits may
also be used.
2. If a wall-mounted ON/OFF control or ther-
mostat is selected mount it in a convenient
location on a wall near the fireplace.
. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 conductor
wire supplied with the unit.
Note: The supplied 15 feet of 2 conductor wire
has one end of each conductor connected to
the gas valve circuit and the other end of each
conductor placed loose inside the bottom
compartment.
Caution: Do Not connect the optional wall
switch to a 120V power supply.
4. If an optional control switch is installed, turn
the appliance-mounted ON/OFF burner control
switch to the OFF position.

B. Electronic Wiring (See Figure 36) –
Note: The electronic appliance must be con-
nected to the main power supply.
1. Route a 3-wire 120VAC 60Hz 1ph power
supply to the appliance junction box.
2. Remove the electrical inlet cover plate from
the side of the unit by removing the plate's
securing screws. See Figure 11A on Page
10.
. Remove the cover plate's knockout and then
feed the power supply wire through the knock-
out opening and into the unit junction box.
4. Connect the black power supply wire to the
red pigtail lead and the white power supply
wire to the common terminal of the outlet
as shown in Figures 36 and 37.
5. Connect the ground supply wire to the pig-
tail lead attached to outlet's green ground
screw.
6. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed
behind the bottom panel.
Optional wall-mounted switch, wall thermo-
stat, or one of the optional remote control
kits may also be used.
7. If wall-mounted ON/OFF control or thermo-
stat is to be used, mount it in a convenient
location on a wall near the fireplace.
8. If an optional wall-mounted control is to be
used, wire it in the low voltage circuit as
shown in Figure 36.
Note: The supplied 15 feet of 2 conductor wire
has one end of each conductor connected to
the gas valve circuit and the other end of each
conductor placed loose inside the bottom
compartment.
9. If an optional control switch is installed,
turn the appliance-mounted ON/OFF burner
control switch to the OFF position.
10. After the wiring is complete, replace the
cover plate.
OPTIONAL BLOWER KIT
(millivolt models only)
If the blower kit is to be installed at the time of
installation or at a later date, the main power supply
and wall switch must be installed at the time of
installation. This will require that the electrical
connections must be made BEFORE the fireplace
is framed and enclosed in the finished walls.
Route a 3-wire, 120 VAC, 60 Hz, 1 ph power
supply and connect to electrical receptacle wires
and wall switch or wall rheostat.

CAUTION
Ground supply lead must be con-
nected to the wire attached to the
green ground screw located on the
outlet box. See Figure 37. Failure to
do so will result in a potential safety
hazard. The appliance must be
electrically grounded in accordance
with local codes or, in the absence of
local codes, the National Electrical
Code, ANSI/NFPA 70-latest edition.
(In Canada, the current CSA C22-1
Canadian Electrical Code).
