CAUTION
Ground supply lead must be con-
nected to the wire attached to the
green ground screw located on the
outlet box. See

ure 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).
CAUTION: Label all wires prior to disconnec-
tion when servicing controls. Wiring errors
can cause improper and dangerous operation.
ATTENTION: Au moment de l'entretien des
commandes, étiquetez tous les fils avant de
les débrancher. des erreurs de cáblage peu-
vent entraîner un fonctionnement inadéquat
et dangereux.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adé-
quatement une fois l'entretien terminé.

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 47) –
1. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed in
the modesty panel. Optional wall-mounted
switch, thermostat, or one of the optional
remote control kits may also be used.
2. If wall-mounted ON/OFF control switch ther-
mostat is selected, mount it in a convenient
location on a wall near the fireplace.
3. 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 con-
nected 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 Figures 48 & 49) –
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
n e
e t i
securing screws (see Figure 13 on Page
11).
3. Remove the cover plate's knockout and
then feed the power supply wire through the
knockout opening and into the unit junction
box.
4. Connect the black power supply wire to the
lower outlet's red pigtail lead and the white
power supply wire to the common terminal
of the outlet as shown in Figures 48 & 49.
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
in the modesty panel.
Optional wall-mounted switch, thermostat, or
one of the optional remote control kits may
also be used. The appliance mounted ON/OFF
switch needs to be relocated onto the optional
style view door, if used.
