Fireplace owners, want to get more heat from your unit without cranking up the thermostat? This GFK21 blower fan kit is exactly what you need! Designed as a direct replacement for Heatilator fireplaces, this kit includes everything required for installation: the blower unit, power cord, variable speed control, magnetic thermostat, wiring harness, and even Velcro mounting strips. The blower moves 80 CFM of air, efficiently circulating warm air throughout your room instead of letting it all go up the chimney. The variable speed rheostat lets you control airflow exactly how you want it, while the magnetic thermostat automatically turns on when the fireplace reaches about 120°F. Compatible with numerous Heatilator models including EDV3633, ND3630, GNRC30, and many others. Installation is straightforward with the included instructions, and the foam pads help reduce vibration noise. Not only does this make your fireplace more effective at heating your space, but it can actually help lower your energy bills too. Stop wasting heat and start enjoying a cozier, more efficient fireplace experience today!
