## Description

Heat-N-Glo Heatilator Direct Vent Fan Control Circuit Module Part Number 4021-708 Blower fan controller for Fan Kit GFK-21B, GFK-160B, GFK-4B

Review: Perfect replacement for existing control - The fan control stopped working in my Heatilator gas fireplace. Thought it was the fan but pressing the test button on the fan control , and the fan working fine, had to be something in the controller. It’s a pain to replace but everything is working fine now.
Review: Just what I needed - Perfect, We bought the house 1 years ago and never really looked at the gas stove, I knew the blower not working and I checked to see if I could get it running and it would run only when I bypassed the module. Finally I decided to get it fixed and after a few minutes installing it using my previous module as a guide, it worked great. It turns on the blower after a set time and turns it off after a set time after the has fireplace is turned off. Not sure how well the blower will heat upstairs but it keeps the downstairs just right.
