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 (on brown wall
switch wire) 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 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.
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.,
or the Canadian Electrical Code, CAN/
CGA C22.1—latest edition.
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 optional control
switch to 120VAC power supply.
1. 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 54)
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 53)
. 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.
2. Open the control compartment access panel.
3. Wire and install the outlet receptacle to
junction box, then install into the chosen
corner of the control compartment as shown
in
Figures 51, 52 and 54
.
4. After the receptacle/junction box wiring is
complete, install the provided metal junction
box cover plate (see
Figure 53)
.
5. Install the snap bushing (on brown wall switch
wire) into the selected cabinet knockout
opening in side cabinets (see
Figures 17-20
and 53).
The snap bushing provides protec-
tion 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 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 54
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.
NOTE: Supply wires may be alternatively con-
nected to the outlet using the screw terminals,
however the black supply wire must be wired to
a terminal that is opposite (across the outlet) the
point where the white supply wire is connected.
