The pilot is provided with a natural gas ori-
ce installed. For propane/LP gas you must
remove it and replace it with an propane/LP
orice. The hardware kit contains an pro-
pane/LP orice with a red stripe for converting
the pilot.
1. Gently loosen and remove the pilot line con-
nection from the bracket (see Figure 16).
2. Replace the injector with the propane/
LP pilot injector with the red stripe (see
Figure 16).
3. Replace and tighten the pilot line to the
bracket.
4. Continue with step 3 under Natural Gas
Installation, page 10.

1. Remove burner inlet tting from burner
pan assembly. DO NOT remove orice
from this tting. The propane/LP burner
inlet tting is included in the hardware kit
(see Figure 14).
2. Be sure to use correct orice for your ap-
pliance. The hardware kit included with
this appliance contains two orices with
a cone-like shape. If you have an 18" set,
orice for burner inlet tting is red; for a 30"
set, it is black. If you have a 24" log set,
orice is already installed inside tting.
3. For an 18" or 30" set, use a 10 mm socket
or nut driver to remove orice from pro-
pane/LP burner inlet tting. Choose cor-
rect orice for your log set size and install
in place of orice you just removed.
4. Using thread sealant (resistant to action
of propane/LP gas) on larger end of tting,
screw burner inlet tting through hole
and into burner manifold, see Figure 15.
Tighten using a wrench.
5 . Follow steps 1 through 12 under Natural
Gas Installation, page 9.

After installation is complete and the unit has
been ignited, it may be necessary to adjust
the pilot. Use a small at-head screwdriver to
turn the ow adjustment screw on the manual
control valve (see Figure 17). Turn the screw
counterclockwise to allow more gas to ow
or clockwise to restrict gas ow. Be careful
to limit the turns to 2
1
/
2
from the fully closed
position. Further turning can result in gas
leaking at the adjustment screw and the pilot
ame size will diminish. The proper pilot ow
will result in a strong blue ame between 1/2"
and 1" long.
