If your fireplace blower has given up, this Hongso GFK4 replacement kit has everything you need to get your heat circulating again! This complete package includes the blower unit itself with ball bearings for smooth operation, a 3-prong power cord, connecting wires, rheostat and thermostat controls, plus Velcro mounting strips and installation instructions. The blower measures 12.5 inches long, 3.73 inches wide, and 3.23 inches high with a 9.5-inch flange opening - so definitely measure your old unit to make sure it fits before ordering. It's compatible with Heatilator, Majestic, Vermont Castings, Monessen, CFM, Northern Flame, and Rotom models among others. The motor runs at 2050 RPM, moves 118 CFM of air, and uses just 31 watts of power. Important note: this blower has a safety feature where it won't start until the thermodisc heats up to about 120°F, so don't panic if it doesn't kick on immediately. Installation is pretty straightforward if you're handy, but always consult your owner's manual too. The aluminum and galvanized steel construction ensures durability, and the insulation is rated for temperatures up to 392°F. No wall switch needed - the included controls handle everything. Much cheaper than buying a whole new fireplace insert, and way more efficient than relying on natural convection alone. Your living room will feel so much warmer with this blower pushing all that heat into the room instead of letting it escape up the chimney!
