Changing Pilot Orifice
The pilot is provided with a natural gas ori-
fice installed. For propane/LP gas you must
remove it and replace it with an propane/LP
orifice. The hardware kit contains an pro-
pane/LP orifice 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).
Figure 16).
3. Replace and tighten the pilot line to the
bracket.
4. Continue with step 3 under Natural Gas

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.

Pilot Flow Adjustment
After installation is complete and the unit has
been ignited, it may be necessary to adjust
the pilot. Use a small flat-head screwdriver to
turn the flow adjustment screw on the manual
control valve (see Figure 17). Turn the screw
counterclockwise to allow more gas to flow
or clockwise to restrict gas flow. Be careful
to limit the turns to 2

leaking at the adjustment screw and the pilot
flame size will diminish. The proper pilot flow
will result in a strong blue flame between 1/2"
and 1" long.
