Vermont Casting 3349, 3340, 3356 4409 410, 3355 manual Remove/replace rear shroud

Radiance Natural Vent Gas Heater

1.The fan kit includes a Blower Assembly and a Rheostat Assembly, connected by a cable. (Fig. 10) The Blower Assembly mounts to the bottom rear of the stove, and the Rheostat mounts to the left side of the valve. The assembly includes a 'snapstat' which automatically turns the fan On (or Off) above (or below) approximately 109˚F. The Rheostat also provides a range of fan speed settings from Off (which overrides the snapstat function) to High. Unpack and inspect the Blower assembly. Confirm that the fan spins freely.
