WARNING
Electronic models of these appliances 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 protection against shock hazard and should be plugged directly into a properly grounded three-
prong receptacle. DO NOT cut or remove the grounding prong from the plug.

See the Operation section on Page 51 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 12).
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 (Figures 29-30). 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, High/Low switch, 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 30).
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.
8. After the wiring is complete, replace the cover plate.
