Step 5. FIELd WIRING

CAUTION
The ground supply lead must be
connected to the wire attached to the
green ground screw located on the
outlet box (see wiring diagrams).
Failure to do so will result in a
potential safety hazard. The appli-
ance 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 discon-
nection 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 peuvent entraîner un fonc-
tionnement 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)
Millivolt units are not provided with any
factory-installed controls; therefore, one of the
optional control switches is required to operate
the unit (ON/OFF Wall Switch, Unit-Mountable
ON/OFF Switch*, Thermostat, Remote Control).
See the fireplace Care and Operation Instruc-
tions for details.
[*If using a Unit-Mountable ON/OFF Rocker Switch
with an optional Style View Door, mount the Rocker
Switch on the door instead of the unit.]
1. If installing an ON/OFF wall switch or ther-
mostat, mount it in a convenient location on
a wall near the fireplace.
2. Wire the control switch within the millivolt
control circuit using the 15 feet of 2 con-
ductor 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
In millivolt systems, do NOT connect
a Wall Switch to a 120V power supply.
B. Electronic Wiring
The electronic gas valve has an integrated ON/
OFF burner control switch. One of the follow-
ing optional controls also may be used: ON/
OFF Wall Switch, Thermostat, Remote Control
n e
e t i
(see fireplace Care and Operation Instructions
for details.).
Note: Electronic models must be connected 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 13, Page 11).
3. Remove the cover plate knockout; then feed
the power supply wire through the knockout
opening and into the unit junction box.
4. See Figures 48 & 49. Connect the black
power supply wire to the lower outlet's red
pigtail lead.
Connect the white power supply wire to the
outlet's common terminal.
5. Connect the ground supply wire to the
pigtail lead attached to the outlet's green
ground screw.
(see Figures 48 & 49)
