## Questions & Answers

**Q: Will this work on model NB3630I?**
A: I don't know but if you look up your fireplace insert online and match model numbers you should be OK. I also measured the back end of my insert where the fan was to be installed and found there was room. Also looked on YouTube and found installation instructions. The install went reasonably well. In order to make room to slide the fan in to position, I hade to disconnect the gas line. That was the scariest to me but turned out to be very straight forward. Sorry I can't help with the model# match.

**Q: Would you be so kind to let us know whether this item is good enough (quality, compatibility, features, noise) for Heatilator GNBC30 fireplace?**
A: I bought this kit for my Kozi pellet stove and it was easy to install, worked very well and noise level is low.

**Q: On your fan unit it is 7.5" long with motor? My opening on the bottom rear is 7 5/8", so if your unit is 7 1/2" it will bearly make in the area**
A: it need hardware to mount it the tape stripes can not support the weight of the unit . the unit will not sit level

**Q: Is everything in the picture included, such as the ducting?**
A: Everything in the picture is included.  There is no “ducting”, the warm air is blown out through the front of the motor.  I was super easy to install, because I already had an available outlet in the fireplace.
