with an accessory mantel, determine whether the power
cord will exit the left side or the right side of the firebox.
Install 1 plastic bushing provided into the 1.5" hole in the

cord into a properly grounded 3-prong wall receptacle near
the firebox.

outlet is not installed in your fireplace, you must install
the GA3555 Outlet kit with cover in your fireplace which
will supply a convenient 3-prong grounded electrical outlet
for your blower. Refer to the installation manual provided
with the model GA3555 accessory for instructions on wir-
ing the duplex outlet.
