Fan/Blower FK-12
This fan kit is carefully engineered and must be in-
stalled only on the specified fireplaces. If you modify the
fan or any of its components, you may possibly create a
fire hazard and will void the warranty. In addition, such
action may void the coverage provided by the owner's
home insurance.
The junction box, on/off switch and fan/blower are fac-
tory installed. This system requires 110-120V AC be
wired to the factory installed junction box before the fire-
place is permanently installed. (Fig. 30)
After connecting 120V AC to the fireplace, test blower
operation. Turn the blower on by pushing the rocker
switch located on the lower right louver panel to "ON".
If the blower does not turn on, push switch to "OFF".
Unplug power cord. Check all wires and terminals for
proper connection. Plug in blower, retest.
