1. If installing an ON/OFF wall switch or thermostat, 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 ft of 2-conductor wire supplied with
the unit (Figure 31).
NOTE: The supplied 15 ft of 2-conductor wire has one end of each conductor connected to the gas valve circuit and
the other end of each conductor placed loose inside the bottom compartment.
In millivolt systems, do NOT connect a wall switch to a 120 V power supply.
Electronic Wiring
One of the following optional controls must be used:
• ON/OFF Wall Switch,
• Thermostat, or
• Remote Control.
See the Operation section on Page 50 for more details.
NOTE: Electronic models must be connected to the main power supply.
1. Route a 3-wire, 120 Vac, 60 Hz, 1 ph power supply to the fireplace junction box.
2. Remove the electrical inlet cover plate from the side of the unit by removing the plate's securing screws
(Table 8).
3. If unit is not supplied with a strain relief, remove the cover plate knockout. 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 lower outlet's red pigtail lead (Figure 32 and Figure 33). 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. Restrain the inlet
power lead per NEC or local codes.
6. If a wall-mounted ON/OFF control or thermostat is to be used, mount it in a convenient location on a wall near the fireplace.
7. If an optional control is to be used, wire it in the low voltage circuit (Figure 32).
NOTE: The supplied 15 ft of 2-conductor wire has one end of each conductor connected to the gas valve circuit
and the other end of each conductor placed loose inside the bottom compartment.
