4. Using thread sealant (resistant to the ac
-
tion of propane/LP gas) on larger end of
fitting, screw the burner inlet fitting through
hole and into burner manifold. Tighten
using a wrench.
5 . Follow steps 1 through 12 under
Natural
Gas Installation
, page 5.
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
hardware kit contains an propane/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 13).
2. Replace the injector (see Figure 13) 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

page 5.
Note:
Follow the instructions in your hearth
kit owner’s manual under the section,
Testing
Burner for Leaks
.
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 screw
-
driver to turn the flow adjustment screw on
the manual control valve (see Figure 14).
Turn the screw counterclockwise to allow
more gas to flow or clockwise to restrict gas
flow. 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 flame size will diminish. The
proper pilot flow will result in a strong blue
flame between 1/2" and 1" long.
