Our GFK21B Blower Fan Kit is designed for Heatilator 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).

    Most Excellent Improvement

    Posted by Frank on 19th Mar 2015

    After checking around for local supplier, $$$, I went on line and culled MyFireplaceBlower out from the low bidders and called to confirm the unit I needed, very helpful, and ordered then. Received it in short order and installed it myself within an hour. The hardest part was cleaning out the lower vent space, which previous owner never thought to do! The unit works great and once our condo is up to temp we lower the stat and the heatilator will hold the temp on cool rainy days, and my bride can now 'warm' up in front of it after walking the dogs. +++ The other item that comes w that makes the job very easy to install, is having the wiring harness, together and ready to hook-up. We leave it at about 1/3 power and it is quiet enough to have on all day without a big distraction and we do appreciate the added warmth! The vidio is also helpful to simplify the task. Quality unit!

    GFK21 Blower Unit

    Posted by Richard Goodman on 2nd Mar 2015

    This was a very easy unit to install and the direction that came with the unit made it quite easy. The unit is not too noisy in even mid to high speed. I would recommend this to anyone that is thinking of installing one.

    GFK21 Blower Review

    Posted by Mike on 4th Dec 2014

    This blower is just what I needed. Somewhat challenging to install if you already have the piping and wiring to the fireplace installed, but not impossible - I did it myself. Blower works well, helps distribute heat out of the firebox, and is not that loud. It can be heard though, if there is no other noise in the room. I have it set on a lower setting as not to blow out all the heat at once. It does take a bit to activate the sensor to kick the motor on, so be patient. The blower runs a while after the fireplace is off too, this is normal. Good Product for the money. It was twice as much at the fireplace shop.
