Convert the gas control valve by changing out
the valve regulator portion of the gas valve.
1.
Using a TORX T20 or slotted screwdriver, re-
move and discard the three mounting screws,
pressure regulator tower and diaphragm/
spring components (see Figure 13).
2. Insure that the rubber gasket is properly
positioned on the new pressure regulator
assembly. Install the new pressure regu-
lator assembly to the valve using the new
mounting screws supplied with the kit.
Tighten screws securely (approximately
25 in-lbs.) See Figure 14.
3. Install the identication label enclosed
with the gas valve regulator to the valve
body where it can easily be seen (see
Figure 14).

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 propane/
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 15).
2. Replace the injector (see Figure 15) with
the propane/LP pilot injector with the red
stripe.
3. Replace and tighten the pilot line to the
bracket.
4. Continue with step 6 under Natural Gas
Installation, page 5.
Note: Follow the instructions in your hearth
kit owner’s manual under the section, Testing
Burner for Leaks.
