CAUTION
Ground supply lead must be con-
nected to the wire attached to the
green ground screw located on
the outlet box. See
Figures 35 and
. Failure to do so will result in a
36
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 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 34) –
1. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed.
Optional wall-mounted switch, or one of
the optional remote control kits may also
be used.
2. If wall-mounted ON/OFF control 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 conduc-
tor wire supplied with the unit.
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 conductor placed on top of the unit.
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 35 and 36)
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
securing screws (see Figure 12 on Page 10).

4. Connect the black power supply wire to the
power outlet's red pigtail lead and the white
power supply wire to the common terminal of
the outlet as shown in Figures 35 and 36.
5. Connect the ground supply wire to the
pigtail lead attached to outlet's green
ground screw.
6. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed.
Optional wall-mounted switch, or one of
the optional remote control kits may also
be used.
7. If wall-mounted ON/OFF control is to be
used, mount it in a convenient location on
a wall near the fireplace.
8. If an optional control is to be used, wire it in
the low voltage circuit (see Figure 35).
Note: The supplied 15 feet of 2 conductor wire
has one end of each conductor connected in
parallel with the appliance mounted ON/OFF
burner control switch and the other end of each
conductor placed on top of the unit.
CAUTION: do Not connect the optional wall
switch to a 120V power supply.
9. If an optional control switch is installed,
turn the appliance-mounted ON/OFF burner
control switch to the OFF position.
