Plug in blower power cord.
a. If your firebox is installed as a freestanding unit with an accessory mantel, determine whether the power cord will exit the left side or the right side of the firebox. Install one plastic bushing provided into the 1.5″ hole in the floor support on the exit side. Install the second bushing provided into the 1.5″ hole in the outer casing through which the power cord will exit (see Figures 5 and 6). Route power cord through plastic bushings and plug the power cord into a properly grounded three-prong wall receptacle near the firebox.
b. If your fireplace system installation is recessed, install one plastic bushing provided into the 1.5″ hole near the middle of the left floor support bracket ( see Figure 6 ).
Route power cord through plastic bushing. Plug the power cord into a properly installed duplex outlet. (If an outlet is not installed in your fireplace, the accessory model GA3555 Outlet Kit with cover can be installed in your fireplace. This will supply a convenient three-prong grounded electrical outlet for your blower. Refer to the installation manual provided with the model GA3555 accessory for instructions on wiring the duplex outlet.)
Note: A qualified installer must make all electrical connections. -
Check to make sure that the power cord and wires are completely clear of the blower wheel and that there are no other foreign objects in blower wheel.

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. In the OFF position, the blower will not operate. In the ON position, the blower will start when the thermostat senses a sufficient increase in firebox temperature (approximately 10 to 20 minutes depending on heat setting).
Note: Your gas logs and thermostat blower will not turn on and off at the
same time. The fireplace may run for several minutes before the blower turns
on.
After the heater modulates to the pilot position, the blower will continue to
run. The blower will shut off after the firebox temperature decreases. Note:
It is safe to operate fireplace with blower turned off. However, the blower
helps distribute heated air from the fireplace. Note: Periodically check the
louvers of the firebox and remove any dust, dirt, or other obstructions.
