    FK4 Blower for Heatilater GNDC33 fireplace

    Posted by D Williams on 16th Nov 2020

    Arrived in a couple of days after ordering. Fits like a glove (a snug glove) but there is room to spare,by just a hair. If you have forearms like Popeye, you might need to recruit a thin armed assistant, but the directions were good, and I could probably install the next one in 45 minutes after plowing through the learning curve on this one. You can hear the blower if its on full, so I set mine at about 70% for my sweet spot. Very good product; I should have done it years ago.

    Arrived on time, easy to install, and fairly quiet. Just in time for the cold weather.

    This fireplace blower for my gas fireplace is working great... I moved into my townhouse last winter and realized at that time that before it got cold again this winter, I needed 2 things, to have my fireplace cleaned and serviced and get a blower on the fireplace. I had the serviceman install the kit which arrived 2 days after I ordered it! Super fast! It was an easy install and I absolutely love the heat coming out from the fireplace instead of just rising up to the ceiling. Some people said the fan was noisy, but it is easily adjustable by the control if you need to turn the fan speed down. I found a happy medium and haven't needed to adjust. I can have the volume of the tv or radio at a normal level and can hold conversations without having to raise voices. The gal on the phone who helped me decide which kit I needed for my fireplace was super helpful, courteous, and polite. She took my order, sent me a confirmation and a tracking number. I was completely satisfied with this company and will recommend it to others if they ask where I got my fireplace blower.

    Easy to following instructions and installation, only downside is the blower noise level at full speed. Have been operating a half speed with good results and very tolerable blower noise level

    Great blower, needs a little engineering.

    Posted by Jim on 25th Dec 2012

    The blower sits about 1" below where the air needs to circulate: therefore a lot of the air circulated in the bottom compartment and did not circulate around the fire box. I added a small piece of sheet metal angle held in place with some aluminum duct tape to close off the gap. Works really well now.
