Propane/LP Gas Conversion
To convert to propane/LP gas, burner inlet
fitting and pilot orifice must be replaced. The
propane/LP burner inlet fitting is supplied with
orifice installed for a 24" log set. If you have an
18" set, you must change this orifice also. See
Figure 1, page 4, for product identification.
Burner Inlet Fitting
1. Remove burner inlet fitting from burner
pan assembly (see Figure 12). DO NOT
remove orifice from fitting. Propane/LP
burner inlet fitting is included in hard-
ware kit (see Figure 13).
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. If
you have a 24" log set, orifice is already
installed inside the fitting. The black orifice
f i r e - p a r t s . c o m will not be used in any multi-side unit and
may be discarded.
3. For an 18" 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 action
of propane/LP gas) on larger end of fitting,
screw burner inlet fitting through hole
and into burner manifold. Tighten using a
wrench.
5 . Follow steps 1 through 12 under Natural
Gas Installation, page 8.

Changing Pilot Orifice
The pilot is provided with a natural gas ori-
fice installed. For propane/LP gas you must
remove natural gas orifice and replace it with
a propane/LP orifice. The hardware kit con-
tains a propane/LP orifice with a red stripe for
converting pilot.
1. Gently loosen and remove pilot line connec-
tion from bracket (see Figure 14).
2. Replace injector (see Figure 14) with
propane/LP pilot injector with red stripe.
3. Replace and tighten pilot line to bracket.
