This kit consists of an extension wire harness for the thermal switch that is used with the blower. On the Vail series of vent free fireplaces, the thermal switch wire is too short to reach properly. As such, the extension harness is clipped in line with the existing harness so that the thermal switch will reach the top of the unit.
