Step 5. FIELD WIRING

CAUTION
Ground supply lead must be con-
nected to the wire attached to the
green ground screw located on the
outlet box. See
Figures 46 & 47
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 45) –
1. Install and wire in the burner control switch.
Install either "a" or "b" below, NOT BOTH
. Fail-
(installing both may result in improper burner
operation).
a. Standard OFF/ON Switch - Install the OFF/
ON burner control switch (rocker switch) as
shown in Figures 45, 46 and 49.
b. Optional Control Switch (OFF/ON wall
switch, wall thermostat or remote control
receiver). Install snap bushing (on brown wall
switch wire) into control switch knock-out in
side panel (see Figures 13, 14 and 48). Wire
the optional control switch within the millivolt
control circuit (as shown in Figure 4 5) using
the 15 feet of brown 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.
Do not connect optional control
switch to 120VAC power supply.
2. Install the junction box and receptacle outlet
to the right 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 50)
GAS VALVE
NOTE: The electronic appliance must be con-
nected to the main 120 VAC power supply.
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 48). If an optional blower is to be installed
place the junction box to the right of the valve
in the front corner.
1. Route a 3-wire, 120 VAC, 60 Hz, 1 ph power
supply to the location on appliance where
junction box is to be installed.

3. Wire and install the outlet receptacle to
junction box, then install into the chosen
GR
corner of the control compartment as shown
in Figures 46, 47 and 49.
JUNCTION BOX
4. After the receptacle/junction box wiring is
complete, install the provided metal junction
box cover plate (see Figure 48).

Install OFF/ON Switch
(millivolt models)
1. Connect the 2 wires (provided in Literature
Kit) to the TP/TH and TH terminals on valve.
2. Pass the 2 wires through the opening where
OFF/ON switch will be installed (left of piezo,
below valve).
3. Connect the two wires to the OFF/ON Switch
(provided in Literature Kit).

5. Install the snap bushing (on brown wall switch
wire) into the selected cabinet knockout open-
ing in side cabinets (see Figures 13, 14 and
48). 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 49.
NOTE: The supplied 15 feet of brown
2-conductor wire has one end of each conductor
connected to the gas valve circuit and the other
end of each conductor placed loose on bottom
of the appliance.
IMPORTANT NOTE: The gas valve OFF/ON
switch is shown in Figure 46 on Page 28. 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.
