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 51) –
Install Optional Control Switch (OFF/ON wall
switch, wall thermostat or remote control
receiver). Install snap bushing (provided in
Electrical Outlet Kit) into control switch knock-
out in side panel (see Figures 17 through 20 and
53). Wire the optional control switch within the
millivolt control circuit (as shown in Figure 51)
using the 15 feet of 2 conductor wire supplied
(route wires through the snap bushing to the
optional control switch). Mount the optional
control switch or wall thermostat in a convenient
location on a wall near the fireplace.
CAUTION
Ground supply lead must be con-
nected to the wire attached to the
green ground screw located on the
outlet box. See Figures 52 & 53 . Fail-
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.
CAUTION
Do not connect optinal control switch
to 120VAC power supply.
2. Install the junction box and receptacle outlet
to the left of the valve in the front (for optional
blower kit). See junction box and receptacle
outlet as explained in steps 1-11 for (B) Elec-
tronic Wiring (on this page).
B. Electronic Wiring (See Figure 54)
Note: The electronic appliance must be con-
nected to the main 120 VAC power supply.
1. Locate the Electrical Outlet Kit provided
(packaged in firebox - contents: junction box, 2
screws, receptacle outlet, OFF/ON rocker switch
-for millivolt units only, and a snap bushing).
Note: The junction box can be installed in any of
the 4 outside corners of the control compartment
(outlet installed in front left corner is shown in
Figure 53 ). If an optional blower is to be installed
place the junction box to the left of the valve in
the front corner.
2. Route a 3-wire, 120 VAC, 60 Hz, 1 ph power
supply to the location on appliance where junc-
tion box is to be installed.
3. Open the control compartment access
panel.
4. Wire and install the outlet receptacle to junc-
tion box, then install into the chosen corner of
the control compartment as shown in Figures
51, 52 and 54.
5. After the receptacle/junction box wiring is
complete, install the field-provided metal junc-
tion box cover plate (see Figure 53).
6. Install the snap bushing (provided in kit)
into the selected cabinet knockout opening in
side cabinets (see Figures 17 through 20 and
53). The snap bushing provides protection for
the wires (see note below) passing through
side cabinet going to an optional burner control
switch Wire in the burner control switch to the
low voltage circuit as shown in Figure 54.
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 con-
ductor placed loose on top of the appliance.
Important Note: The gas valve OFF/ON switch
is shown in Figure 56 on Page 30. It is integral
with the gas valve and should be set to the
ON position.
WARNING
Electronic models of these appli-
ances are equipped with a three-
prong (grounding) plug utilized
in connecting the electronic
components to the junction box
in the lower compartment. This
grounding plug provides protec-
tion against shock hazard and
should be plugged directly into
the properly grounded three-
prong receptacle. DO NOT cut
or remove the grounding prong
from the plug.
