CONVERSION INSTRUCTIONS
Burner Orifi ce Conversion
1. Using a #10 short phillips screwdriver, remove top mounting screw
holding pilot burner shield in place
(see
Figure 4
)
.
2. With
orifi ce mount exposed, use a 7/8” open-end back-up wrench
on 3/8” fl are adaptor and remove 3/8” fl are fi tting at the end of 3/8”
fl are adaptor. This will prevent spinning and damage to the fl exible
tube
(see
Figure 4
)
.
3. Using the 7/8” wrench, remove the remaining orifi ce assembly from
the burner tube.
4. Separate the 3/8” male fl are adaptor from the existing natural gas
orifi ce fi tting and save for later reassembly.
5. Thread the propane/LP gas orifi ce into the propane/LP gas air-mixer
fi tting using a 3/8” deep socket driver.
NOTE
: LP gas airmixer fi tting
has six (6) holes. The natural gas fi tting has no holes.
6. Apply a light amount of propane/LP resistant sealant to both threaded
ends of LP air-mixer fi tting.
7. Thread large threaded end of propane/LP air-mixer fi tting into burner
tube and tighten with 7/8” wrench until fl ange is fully-seated into
bracket.
8. Replace 3/8” fl are adaptor onto exposed thread on propane/LP
gas air-mixer fi tting. Use 7/8” back-up wrench on fi tting to prevent
turning burner tube.
9. Retighten fl are fi tting on fl exible manifold tube with the 3/4” open-
end wrench and 7/8” back-up wrench.
10. Reattach pilot shield onto burner bracket with screw removed in
step 1.

Gas Control Valve Conversion
Convert the gas control by swapping out the valve regulator portion of
the gas valve.
1. Using a Torx T20 or slotted screwdriver, remove and discard the
three mounting screws, pressure regulator tower, and diaphragm/
spring components
(see
Figure 5
).
2. Ensure that the rubber gasket is properly positioned on the new pres-
sure regulator assembly. Install LP pressure regulator assembly to
valve using the new mounting screws supplied with the kit. Tighten
screws securely (@ approximately 25 in-lbs.)
(see
Figure 6
).
3. Install
the
identifi cation label enclosed with the gas valve regulator
to the valve body, where it can easily be seen
(see
Figure 6
)
