6.Place the blower against lower rear wall of firebox outer wrap- per with the exhaust port directed upward. Align the holes in top mounting tabs of blower with holes in wall of wrapper (see Figure 18, page 6). Using 2 screws provided, mount blower and tighten screws securely.

7.Be certain that all wire terminals are securely attached to ter- minals on blower motor and that the screw retaining the green ground wire is tight.

8.Place control knob provided on plastic control shaft of speed control.

9.Mount the speed control on the front leg of the left floor support bracket using 2 screws provided (see Figure 19). Note: Some remote ready fireplace models have the gas control located near the left floor support bracket. For these models, mount the blower speed control onto the right floor support bracket.

10.Plug in blower power cord.

a.If your fireplace system 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 1 plastic bushing provided into the 1.5" hole in the floor support bracket on the exit side (see Figure 20). Install the second plas- tic bushing provided into the 1.5" hole in the outer casing through which the power cord will exit. Route power cord through both plastic bushings 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 if an outlet is not installed in your fireplace, you must install the GA3555 Outlet kit with cover in your fireplace which will sup- ply a convenient 3-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.
