WARNING: A licensed elec-
trician must connect the wiring
harness to electrical supply fol-
lowing all local codes. Electri-
cian must provide a clamp on
the box cover to secure the wir-
ing. Wiring should be routed
through the bushing in the hole
on the outer casing of fireplace.
1. Install a snap bushing found in hardware kit
into one of the holes on rear of valve cover
shield. The other hole is for a strain relief
clamp (not supplied) to secure incoming elec-
trical supply.
2. Follow steps 2 through 6 in Installing Blower
Accessory, page 14.
3. A licensed electrician must follow the wiring
diagram to connect incoming electrical sup-
ply to fan kit wiring harness (see Figure 18).
4. Plug power cord to the outlet receptacle (not
provided) as shown in Figure 19. Wind the
extra power cord and tie with plastic wire strap
(see Figure 19). Set the power cord bundle
between the burner bracket and outer casing,
away from the burner.
5. Test to make sure the blower is working
properly.
6. Reinstall upper louver assembly (see Figure 14,
page 13) and close lower louver.

8. Reconnect red wire to switch position 3. Re-
connect blue wire to switch position 1. Re-
connect green and white wires.
9. Install the switch plate on the valve cover shield
with 2 #10 screws provided (see Figure 17).
Route power cord out of the cabinet by insert-
ing it through the bushing on the outer casing
(see Figure 15, page 14). Plug fan kit into 120-
Volt grounded power supply and test operation.
Note: When switch is in the AUTO position,
the fan will start after the fireplace has run for
a few moments. The fan will continue to run
for several moments after the fireplace has been
turned off. When switch is in the ON position,
the fan will run until turned to OFF. Reinstall
upper louver assembly (see Figure 14, page 13)
and branch support. Close lower louver door.
Extension Cord
Use extension cord if needed. The cord must have a
three-prong, grounding plug and a three-hole recep-
tacle. Make sure cord is in good shape. It must be
heavy enough to carry the current needed. An under-
sized cord will cause a drop in line voltage. This
will result in loss of power and overheating. Use a
No. 16 AWG cord for lengths less than 50 feet.
