    Doesn't go into NDV3630i without a fight...but I like it now that it's in.

    I had to take the motor off of the blower to get it under the firebox, then reattach it when almost in position.

    Fireplace blower

    Posted by Rand on 24th Dec 2018

    I recently purchased a blower for my fireplace and installed it myself. After going online and looking at the information your company provided I was confident the job would go fairly well. I was very pleased with the instructions and how easy it was to install and the performance of the fan is fantastic I cannot say enough about the product and your company. Thank you very much

    Blower Fan Control Unit

    Posted by Otto Miller on 18th Jun 2018

    My fan control unit was not working when I received it. I contacted the company and they sent me out a replacement unit free via second day postage. I received the replacement unit and it works fine. I was also provided a pre-paid postage to return the old unit which I did. Great customer service.

    Easy to follow instructions & illistrations. Had to disconnect the gas supply line to the gas valve to allow easy installation of the blower motor. I like the choice of blower fan speeds.

    Easy to install and works great. Variable speed is a nice feature. Nice to capture more heat from the fireplace.

    very good company support.

    Posted by A Customer on 21st Sep 2013

    Company was very helpful helping when I did the install. The jumper for the power strip inside cabinet was not in the instructions. I will also install a jumper for the temp switch because with the gas fireplace there is not much of a heat up period and the heat and power to the fan goes away when I shut off the wall switch. I want to have the fan go on and off with my wall switch. The fan is not very powerful but have not had cold weather to try it out yet. Thanks to the phone help your company gave me. ---------------------------------------------- Response From: MyFireplaceBlower- We have revised the instructions including detailed pictures and diagrams which include the jumper wire. This fan is the smallest fan we offer, this is the fan which is provisioned by Heatilator for this fireplace model.
