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 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 32-33). 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.
