Electronic Wiring
One of the following optional controls must be used:
•
ON/OFF Control
•
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 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 black and 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.
NOTE:
The supplied 15 ft of 6-conductor wire has one end of each conductor connected to the control circuit and
the other end of each conductor placed loose inside the bottom compartment.
7.
After the wiring is complete, replace the cover plate.
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.
13.
Connect the Gas Line
All codes require a shutoff valve mounted in the supply line.
Figure 35
illustrates two methods for connecting the
gas supply. The flex-line method is acceptable in the U.S., however, Canadian requirements vary depending on
locality. Installation must be in compliance with local codes.
