Oxford Direct Vent / Natural Vent Gas Heater

Install the Optional Fan

If you are installing the optional convection Fan Kit
#2767 (FK26), continue here. If you are not installing a
Fan Kit, go to Page 15, Venting System Assembly.
1. The fan kit includes a Blower Assembly and a Rheo-
stat Assembly, connected by a cable. (Fig. 12) The
Blower Assembly mounts to the bottom rear of the
stove, and the Rheostat mounts to the valve cov-
erplate. The assembly includes a 'snapstat' which
automatically turns the fan On (or Off) above (or
below) approximately 109°. The Rheostat also pro-
vides 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.
WARNING
This appliance is equipped with a three-prong
(grounded) plug for your protection against shock
hazard and should be plugged directly into a prop-
erly grounded three-prong receptacle. Do not cut or
remove the grounding prong from this plug.
