    Product works exactly as described. Installation was straight forward as detailed instructions were provided with the product. Wish I would have purchased one of these sooner.

    Blower kit

    Posted by Peter on 3rd Sep 2018

    Easy install. Louder than expected but has multiple speed settings so I slowed it down to reduce the noise. I have heard from others these don’t last long and get louder and squeaky after a while. Time will tell so can’t give it 4 stars yet.

    Easy install, detailed instructions and videos

    Posted by Marshall on 19th Jan 2018

    I went with this brand because it had the exact model of my gas fireplace, they had installation videos and included EVERYTHING needed to get the job done. I had this finished in less then an hour. That includes cleaning out the dust and carefully reading the instructions!

    Good product

    Posted by Unknown on 16th Jan 2018

    I recently installed the GFK4B fan kit on our gas fireplace. It now allows me to get more heat into the room instead of sending it all out the chimney. It is a quick and easy installation and works as advertised. The only negative feedback I can give is I feel the fan is a little noisy It it was quieter I would have given it 5 stars

    Easy to install/ directions are spot on/ real quiet at medium speed/ have installed many different blowers in my trade,and this one is definitely supreme over the rest. Planning on installing more , as I get more work. Great people to deal with too. Thank you Mike

    I installed this in a Heatilator NVD4236i. This fan kit is very easy to install and works great. Instructions are easy to follow. Highly recommend this product.

    Blower fan

    Posted by Johnny on 26th Nov 2015

    It was very easy to install, but I am disappointed in the performance. It does not seem to push out the warm air from the fireplace that I hoped it would and not as quiet as I was hoping. It is the model that was required for the model of my fireplace. Price was right but wish there had been more options or more info to go off of. ------------------------------------------ MyFireplaceBlower Response: Feel free to contact us to double check this blower is installed correctly and we can go through some trouble shooting techniques.
