VENTED GAS LOGS
INSTALLATION
Continued
Propane/LP Gas Conversion
To convert to propane/LP gas, the regulator
pressure must be reset. Also, the burner inlet
fitting and pilot orifice must be replaced. The
propane/LP burner inlet fitting is supplied
with the orifice installed for your log set.
Burner Inlet Fitting
1. Remove the burner inlet fitting from the
gas control assembly (see Figure 14).
DO NOT remove the orifice from this
fitting. The propane/LP burner inlet fit-
ting is included in the hardware kit (see
Figure 15).
2. Be sure to use the correct orifice for your
appliance. The orifice kit included with
this appliance contains an orifice in-
stalled in an air mixer fitting.
3. Using thread sealant (resistant to the
action of propane/LP gas) on smaller
end of fitting, screw the burner inlet fit-
ting into the outlet side of the gas con-
trol. Tighten using a wrench.
4 . Follow steps 1 through 14 under Kit As-
sembly, pages 9 and 10.
