PROPANE/LP GAS CONVERSION
To convert to propane/LP gas, burner inlet
fitting and pilot orifice must be replaced.
Propane/LP burner inlet fitting is supplied
with orifice installed for a 24" log set. If you
have an 18" or 30" set, you must change this
orifice also. See Figure 1, page 5 for product
identification.
Burner Inlet Fitting
1. Remove burner inlet fitting from burner
pan assembly. DO NOT remove orifice
from this fitting. Propane/LP burner inlet
fitting is included in hardware kit (see
Figure 12).
2. Be sure to use correct orifice for your ap-
pliance. The hardware kit included with
this appliance contains two orifices with
a cone-like shape. If you have an 18" set,
orifice for burner inlet fitting is red; for a 30"
set, it is black. If you have a 24" log set,
orifice is already installed inside fitting.
3. For an 18" or 30" set, use a 10 mm socket or
nut driver to remove orifice from propane/LP
burner inlet fitting. Choose the correct orifice
for your log set size and install in place of
orifice you just removed.
4. Using thread sealant (resistant to the ac-
tion of propane/LP gas) on larger end of
fitting, screw burner inlet fitting through
hole and into burner manifold (see Figure
13). Tighten using a wrench.
5 . Follow steps 1 through 12 under Natural
Gas Installation, page 10.
