    Easy to install.

    Posted by Kris on 9th Mar 2021

    Just installed this myself. It was pretty straightforward, also I found a very helpful video on YT. Instructions included were helpful especially with the YT video. Blower worked well, It definitely helps move heat from around the fireplace but it’s nowhere near as much heat as with a regular wood burning fireplace. Definitely worth it for our family.

    Quick delivery once my order was made. Installation was a breeze, all required electrical connections were included for my application. Up and running within 30 minutes. I run the fan on medium low because of the fan hum at higher speeds. My wife is very satisfied with how much warmer our family room is when the blower is on and moving warm air into the space. She has opined that, "You should have done this sooner!"

    Great Blower Add-on

    Posted by Chuck on 4th Dec 2020

    Almost brought a cheap one from Amazon. This one is much better with all the wiring kit and no thermal switch, and the I really like the preset timer for the blower, turns "on" after 7 min of the fireplace fire up and "off" after 12min , one less remote or switch to deal with

    Love how this works. It was simple enough to hook up and half of the price to have someone come install it.

    Was having a smell in the house when I used my fireplace and found out it was due to the heat from the fireplace was warming up the mantel and making the urethane smell. Installed the fan and all is good. Installation was very easy and the house is warmer and no smell.

    Fireplace Blower Kit GFK4B

    Posted by Ted Cam on 7th Oct 2019

    Great product for a good price! DO NOT BUY THE CHEAP VERSIONS OF THIS ON AMAZON! Watch the video that compares this to the cheap competitors and see for yourself. The directions were good, not great, but I read through all of the directions before I started the test fit dry run. Once the test fit was complete, I set up the removable plastic strips to have a small bend that allows you to grip it with two fingers while your arm is extended into the back of the fireplace. I positioned the fan in the back center as instructed. Just watch your left side where the motor is located, so that it does not touch the walls and cause vibration. I set it on Low due to the fan motor noise. This setting is the quietest and still blows air into the room. I had to plug the unit I to the AUX plug instead of the Fan plug so that the fan will operate for 12 minutes after you switch off the fireplace and Main Gas. Works as they advertise. 4 stars instead of 5 due to the fan noise and lack of color pictures in the directions! Thank you my fireplace!

    Looked around and read reviews for various models. This ll”looked” to be a much better quality fan than the others. It was a little bit more expensive but well worth the few extra dollars. Easy to install and instructions were pretty good and not difficult to follow. I would highly recommend this fan.

    Fireplace blower for Heatilator fireplace

    Posted by Carol Pharr on 24th Dec 2018

    It was a lot harder to install than other reviewers had said but the people at My Fireplace Blower provided excellent technical support and were just wonderful to work with. Once my friend finally got the blower installed, it works great.

    GFK4B Fan Kit

    Posted by Tom Frank on 29th Nov 2018

    The fan kit was pretty easy to install. My gas connection was on the left side with the fireplace controller electronics module on the right. There would have been a little more room to maneuver the fan unit on the left, but I didn't want to disconnect the gas supply if I didn't have to. After moving the existing wiring to the sides, I was able to get the fan unit into the fireplace with a slow, methodical, turning and turning the fan unit as I slowly guided past obstructions. Once it was in place, the wiring was straight forward and simple based on the instructions that came with the unit. Perhaps I was lucky, but my Heatilator fireplace had a small pre-drilled hole in the metal bottom near each front corner where the two ground wires from the fan kit could be easily screwed into place.connect . The fan works very well, although the fan noise is a bit more than I like at it two highest settings, so I just run it in the second lowest speed, which seems to be adequate for the where I live. At least I know there is some reserve capacity if it got really cold and I want more room heating. I'm very pleased with the quality and performance of this fan kit.
