Our GFK4B Blower Fan Kit is designed for Heatilator and other fireplaces to circulate air around the firebox and enhance heat output. This complete fireplace blower kit offers a low cost solution to push heat created by the fireplace into your living space.

A speed control module with timer circuit is included with the blower kit which automatically turns the fan ON / OFF at preset times and is equipped with a Speed Button to provide a quiet airflow at the desired speeds. The timer circuit will delay fan operation; by automatically turning ON the fan 7 minutes after the main flame has been turned ON (After the fireplace has warmed up) and turning the fan OFF 12 minutes after the main flame has been turned OFF (After the fireplace has cooled down).

    Easy to install, fairly priced, and works as advertised. I recommended this to my neighbor and he bought and installed the same unit. Great product!

    Love it!

    The blower works great and throws out some serious heat from my gas fireplace. The only downside is that it’s a bit loud when set on the higher levels. Also, the illustrations on the instruction could be improved to show exactly what the “piggyback” wire is and how it’s installed. Not clear at all for someone who has never used a piggyback wire before.

    Super easy. This was a refit of a blower that had aged out. Exact fire replacement made this an easy project!
