Wiring - Fireplace (See Figures 26 and 27 on Page 20)
Note: These electronic appliances must be connected to the main power
supply. The gas valve is set in place and pre-wired at the factory.
1. Route a 3-wire 120Vac 60Hz 1ph power supply to the appliance junc-
tion box.
2. Remove the electrical inlet cover plate from the side of the unit by remov-
ing the plate's securing screws (see Figure 8 on Page 10).
3. Remove the cover plate's knockout and then feed the power supply wire
through the knockout opening and into the unit junction box.
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 26 and 27 on Page 20.
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 26 on Page 20).
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.
10.After the wiring is complete, replace the cover plate.
Wiring - Power Vent Termination
Alternate Instructions (For use when access to the termination is easy
and a secondary electrical junction box installation is not desired).
• Remove the junction box cover from the termination by removing the
attaching screw (refer to Figure 22).
• Loosen the strain relief on the termination shown in Figure 22. Pull
the pigtail in and shorten it to fit within the junction box cover.
• Route 14 gauge AWG grounded Romex wiring (not provided) from
fireplace to the J-Box at the termination. Ensure the wiring is safety
plated to prevent damage by framing nails and finish drywall screws.
Route the wire into the lower control compartment and cut to length
before installing the terminals. Install provided wiring hardware on the
fireplace end of the Romex wire.
