Universal Applications: The GFK4 blower kit can be used in universal applications, so long as adequate mounting space is available. 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. Kit includes ball bearing blower, 3-prong power cord, rheostat variable speed control, thermostat, pre-installed neodymium magnets for mounting and noise reduction padding. Comes fully assembled and pre-wired. Assembled and tested in Racine, WI USA. 100% Sealed Ball Bearing – Powerful, Quiet, Superbly Balanced, Energy Efficient and Long Lasting.
