Electronic Wiring DRT4000-C series
One of the following optional controls must be used:
• ON/OFF Wall Switch,
• Thermostat, or
• Remote Control
See the
Operation
section on
Page 54
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,
Page 18
)
.
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
(
Figures 30A & 30B, Pages 41 & 42
)
.
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.
