Our redesigned Buck MA-5126715 blower fan kit assembly for Buck models FP21, FS21, 51, 74, 261, C22, C75 and C262 is a vastly improved version of the original kit. Features a high-performance 100% ball bearing blower with metal wheels to prevent warping, melting and cracking. Improved high-temperature rated blower extends blower lifespan and improves air flow. We accomplish this through higher temperature rated motor insulation and re-engineered high temp ball bearings. These added features also make for an extremely quiet and well-balanced blower assembly! Adding this blower to your Buck fireplace can significantly improve room air circulation and is easily DIY installed, even after the fireplace has been installed. How to Install the MA-5126715 Blower Kit. Remove access door panel located at bottom of unit. Your motor assembly comes with a bracket already attached to the motor. Align the holes in motor bracket with holes in motor mount. Secure bracket with two 1/2 hex head screws provided. Remove the protective backing off the rheostat indicating label and place the hole in center of label to line up with hole in the right side hearth support as you face the unit. Place label so “OFF” position is at the 8 O’Clock position and “LOW” is at 4 O’Clock position. Mount rheostat by placing it behind hearth support with wires on bottom side. Place plastic sud support with wires on bottom side. Place plastic stud through hole in bracket and secure with rheostat mounting nut. Place indicator knob on plastic stud. Remove strain relief cover from hearth support and discard. Mount power cord strain relief holder in cover mounting holes. Place thermsotat behind “C” clip located under hearth to the right of motor. Use cable tie to secure loose wires. Re-install access door panel. Plug power cord into supply outlet. Place rheostat indicating knob in position desired. When heater reaches temperature, fan will operate at desired speed. NOTE: It may be necessary to clean fan blades for maximum performance. This should be done several times during the heating season to improve blower lifespan. Dust and dirt buildup on fan blades will shorten motor life and restrict air flow, which can damage the motor.
