protected by a towel. 
4. Take the logset and all other loose parts out of the
firebox and set them aside in a protected area for 
installation after the venting is complete.

If you are installing the optional convection Fan Kit 
#2960 (FK28), continue here. If you will not install the 
Fan Kit, go to Page 15, Venting System Assembly.
1. The fan kit includes a blower assembly and a 
rheostat assembly connected by a cable. (Fig. 14) 
The blower assembly and the rheostat mount to the 
rear shroud of the stove. The assembly includes a 
‘snapstat’ which automatically turns the fan ON (or 
OFF) above (or below) approximately 109° F (43° 
C). 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.
2. Attach the snapstat assembly to the snapstat brack-
et with two (2) sheet metal screws. (Fig. 13) Remove 
the 1/4-20 x 3/8” hex head bolt installed in the hole 
in the right rear ledge of the firebox. Use that bolt 
to secure the snapstat bracket to the firebox. The 
mounting hole is slotted to allow you to adjust the 
bracket so the snapstat bracket head makes contact 
with the firebox. (Fig. 13)
