If your fireplace has a junction style outlet with a “FAN”, “REM/AUX” and “TRANS” outlet, please use the “REM/AUX” outlet, which both have constant power. The “FAN” outlet has switched power and requires a jumper wire to make hot.If the blower isn’t turning on, your thermostat is likely not getting hot enough and may need to be re-positioned. Feel free to send us a direct message and we can help troubleshoot any issues you’re having with the blower.

Review: Excellent Blower Fan - For those with the issue of not having Velcro, the manufacturer no longer uses Velcro and instead uses a magnetic attachment. It works great! No need to fumble with Velcro! Packaged very well and super easy to install. My first day and it works great!
Review: Super quiet and easy to install. - This was super easy to install and fit perfectly. At first I was irritated because I thought it wasn’t turning on until I felt the heat blowing out. The entire time it was actually on but was extremely quiet. Great product and well worth the money.

## Questions & Answers

**Q: Heatilator told me that i need the GFK4B model. This one does not say B. Do you have the B?**
A: Hi Mike,  great question.  Our GFK4 is essentially the same thing as the GFK4A or GFK4B.  The "A" stood for automatic, which meant the kit included a thermostat.  The "B" was used by some brands to indicate that a timer feature was added to the kit, but most manufacturers use "A" and "B" synonymously to mean that the blower kit is automatic.  Our GFK4 covers all examples, so if Heatilator recommended the GFK4B, our GFK4 will work wonderfully.  If you have any additional questions, just let us know.

**Q: i have a lopi berkshire gas stove. i would like to install a fan. will this unit gfk4 fit in my stove? how many sones???  thank you**
A: Bob, if you have 3.5 inches of clearance between the bottom of the lower opening and the top of that same opening you should be able to get this in.  You will have to remove anything that is in the bottom of the stove except the gas valve itself.  That means the electrial unit that is there and the gas line that feeds the burner unit.  Not too bad if you are comfortable with doing it, but if you are uncomfortable with removing gas lines, etc. someone else should do this for you.  It takes about 45 minutes from start to finish.

**Q: Is this correct for the Heatilator nb4842 model?**
A: Yes, the GFK4 is the correct blower kit for the NB4842 model!  Regards, Jason

**Q: Will the fit the Desa International fireplace v42ps-a??**
A: Yes, this will fit the V42, but we typically use the larger BKT blower kit on these models.  I do have the BKT blower kit available here on Amazon, so let me know if you have any questions.  Regards, Jason

### ⭐⭐⭐⭐ Works Ok
*by D***. on January 1, 2013*

I have one in our fireplace, I installed this one in a friend's fireplace, and two other friends each have one similar to this also. They are well built units and work well. I also want to mention that the support from "fireplaceblowers" is excellent. They promptly answered questions by email and were available by phone as advertised on their website. My installation is good but my friend's installation had an issue. These work by placing the blower below and at the back of the firebox so it blows air up the back air gap and out the top grill. The issue is my friend's fireplace has a much larger air gap (3" vs 1" in my fireplace) along the sides of the firebox which allowed a lot of the air to go down the sides to the bottom instead of out the top grill and thus recirculate into the blower. This heated up the gap under of the fireplace box which should have been cooled by incoming air. Fireplaceblowers immediately answered my phone call but, unfortuneately, did not have a ready solution. However, being able to discuss it with them helped as I devised a solution. I bought a 3x3 ft sheet of galvanized steel at Lowes, cut two 2.75 inch strips and put one strip in each air gap along the sides of fireplace to restrict the air flow along the sides. I left the 0.25 inch gap to allow side air flow if the fireplace is run without the blower. I also tested this reduced air gap to ensure I did not overheat anything but since the 3" air gap is still there, the only thing is a slight restriction of a thermally driven flow. Without an exact sketch of how I placed these sheet strips, I hope you get the idea. This worked to restrict downward side air flow, recirculating air along the sides is minimal, and good warm air is flowing out the top grill.
