Figure 14 - Installing Propane/LP Pilot Orifice
Pilot Injector
Changing Pilot Orifice
The pilot is provided with a natural gas orifice installed. For
propane/LP gas you must remove it and replace it with an propane/
LP orifice. The accessory hardware kit contains an propane/LP
orifice with a red stripe for converting the pilot.
1. Gently loosen and remove the pilot line connection from the
bracket (see Figure 14).
2. Replace the injector (see Figure 14) with the propane/LP pilot
injector with the red stripe.
3. Replace and tighten the pilot line to the bracket.
4. Continue with step 3 under Natural Gas Installation, pages 7
and 8.

Propane/LP Gas Conversion
To convert to propane/LP gas, the burner inlet fitting and pilot orifice
must be replaced. The propane/LP burner inlet fitting is supplied with
the 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 3 for product
identification.
Burner Inlet Fitting
1. Remove the burner inlet fitting from the burner pan assembly.
DO NOT remove the orifice from this fitting. The propane/LP
burner inlet fitting is included in the hardware kit (see Figure 12).
2. Be sure to use the correct orifice for your appliance. The hard-
ware kit included with this appliance contains two orifices with
a cone-like shape. If you have an 18" set, the orifice for the
burner inlet fitting is red; for a 30" set, it is black. If you have
a 24" log set, the orifice is already installed inside the fitting.
3. For an 18" or 30" set, use a 10mm socket or nut driver to re-
move the orifice from the propane/LP burner inlet fitting.
Choose the correct orifice for your log set size and install in
place of the orifice you just removed.

4. Using thread sealant (resistant to the action of propane/LP gas) on
larger end of fitting, screw the 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, pages
