de cáblage peu-vent entraîner un fonc-
tionnement inadéquat et dangereux.
Verify proper operation after servicing.
S'assurer que l'appareil fonctionne adé-
quatement une fois l'entretien terminé.

ELECTRONIC WIRING DIAGRAM FOR GRAVITY VENT FIREPLACES
(See Figure 36 for detailed drawing
of junction box / receptacle wiring.)
Electronic Wiring
(See Figures 35 and 36)
Note: The electronic appliance must be
connected to the main power supply.
1. Route a 3-wire, 120 Vac, 60 Hz, 1ph power
supply to the appliance junction box.
2. Remove the electrical inlet cover plate from
the side of the unit by removing the plate's
securing screws (
see Figure 14, Page 17).
3. Remove the cover plate’s knockout and 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
power outlet’s red pigtail lead and the white
power supply wire to the common terminal
of the outlet as shown in
Figures 35 and 36.
5. Connect the ground supply wire to the pig-
tail lead attached to outlet's green ground
screw.
6. Appliance-mounted ON/OFF burner control
switch (rocker switch) is factory installed.
7. After wiring is complete, replace the cover
plate.
