WARNING

This appliance is equipped with a three-prong (grounded) plug for your protection against shock hazard and should be plugged directly into a properly grounded three-prong receptacle. Do not cut or remove the grounding prong from this plug.

Install the Optional Fan

If you are installing the optional convection Fan Kit #2767 (FK26), continue here. It is easiest to install fan kit before connecting gas line. If you are not installing a Fan Kit, go to Page 16, Venting System Assembly.

1.The fan kit includes a Blower Assembly and a Rheo- stat Assembly, connected by a cable. (Fig. 15) The Blower Assembly mounts to the bottom rear of the stove, and the Rheostat mounts to the valve cover- plate. The assembly includes a ‘snapstat’ which au- tomatically turns the fan On (or Off) above (or below) approximately 109˚. 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.
