Open lower louver panel or remove for
easier access.
2.
Place the blower against the lower rear wall
of firebox outer wrapper with the exhaust
port directed upward. Align the holes in
the top mounting tabs of blower with holes
in wall of wrapper (see Figure 31). Using
the two screws provided, mount blower
and tighten screws securely.

Be sure to securely attach all wire ter-
minals to terminals on blower motor
and that the screw retaining the green
ground wire is tight.

Remove screws securing the plate con-
taining the ON/OFF switch to the bot-
tom of the firebox and set aside.

" hole in the outer cas-
ing through which the power cord
will exit. Install the second plastic
bushing provided into the floor sup-
port bracket if exiting through the
right side (see Figure 33). Route
power cord through (both) plastic
bushing(s) and plug the power cord
into a properly grounded 3-prong
wall receptacle near the firebox.
b. If your fireplace system installation
is recessed and/or pre-wired, a
qualified installer must make all elec-
trical connections for the outlet kit
included with the fireplace.

Check to make sure that the power cord
is completely clear of the blower wheel
and that there are no other foreign ob-
jects in blower wheel. Turn blower on
and check for operation. Turn blower

wise before continuing.
