Install the Optional Fan - RADVT Series
If you are installing the optional convection Fan Kit #767
(FK6), continue here. It is easiest to install fan kit before
connecting gas line. If you are not installing a Fan Kit, go
to Page 17, Venting System Assembly.
1. The fan kit includes a Blower Assembly and a Rheostat
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 coverplate. The as-
sembly includes a 'snapstat' which automatically turns
the fan On (or Off) above (or below) approximately 109°.
The Rheostat also provides a range of fan speed set-
tings from Off (which overrides the snapstat function) to
High. Unpack and inspect the Blower assembly. Confirm
that the fan spins freely.
