Shaft Operating the Blower
Light your gas appliance with the blower
off. After about 15 minutes, turn the blower
on to deliver heated air at the top louvers.
The blower features a variable control which
allows you to select the speed you desire.
Note: Periodically check the louvers of the
firebox and remove any dust, dirt, or other
obstructions.
7. Plug in blower power cord.
a. If your firebox is installed as a free-
standing unit, determine whether the
power cord will exit the left side or the
right side of the firebox. Install 1 plas-
tic bushing provided into the 1
1 /
2
" hole
in the floor support on the exit side.
Install the second plastic bushing pro-
vided into the 1
1 /

" hole in the outer
casing through which the power cord
will exit (see Figure 11). Route power
cord through both plastic bushings
and plug the power cord into a 3-
prong grounded wall receptacle near
the firebox.
b. If your firebox installation is re-
cessed and/or pre-wired, see Built-
In Installation of Blower Accessory,
