GAS CONTROL VALVE CONVERSION
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 identification label enclosed
with the gas valve regulator to the valve
body where it can easily be seen (see
Figure 14).

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 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 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.
Pilot Flow Adjustment
If pilot flow is weak adjustments can be made
with the pilot adjustment screw. The screw is
located below the wire harness on gas valve
body (see Figure 14).
