Step 3. Using a 5/16 in. hex-head nut driver, remove the
two (2) screws securing the control compartment door
to the right side of the appliance.
Step 4. Rotate the control compartment door into the control
compartment and lift it away from the appliance. Set
aside the screws and control compartment door in a
secure location for later reinstallation.
NOTE: For Step 6 through Step 8, refer to the
instructions provided with the SIT valve for more
information.
Step 5. Using a Torx T20 driver, remove and discard the two
pressure regulator mounting screws, the stepper
motor pressure regulator tower, the spring, and
the diaphragm assembly. Properly dispose of all
removed components.

Step 6. Confirm the rubber gasket is firmly attached and
properly positioned on the back of the replacement
stepper motor pressure regulator. Install the new
stepper motor pressure regulator assembly using the
supplied screws. Securely tighten the screws (25 lb-in).
Step 7. Attach the enclosed valve identification label to the
valve body where it can be easily seen.
Step 8. Make stepper motor pressure regulator and valve
electrical connections.
Step 9. Refer to Figure 3 and remove the pilot hood assembly
to access the hex-head pilot orifice. Pull up sharply on
the pilot hood to remove it.
NOTE: Use care to avoid damaging the
igniter assembly. The pilot hood is secured with a
spring clip; do not remove this spring clip.

Step 11. Reinstall the pilot hood by orienting it over the pilot
orifice and pressing down until it snaps into place.
Step 12. Using a 1/2 in. deep socket or open ended wrench,
remove the main burner orifice.
NOTE: Use a 5/8 in. open ended wrench to secure the
orifice holder while removing the main burner orifice.
Step 13. Verify the proper burner orifice size needed
(see Table 1).
Step 14. Using a small amount of pipe thread joint compound
and a 1/2 in. deep socket / open ended wrench, install
the new burner orifice.
NOTE: Ensure propane resistant compounds are
used in propane applications. Do not use pipe joint
compounds on flare fittings. Do not get any pipe joint
compound in the burner orifice.
Step 15. Replace the burner assembly, and ensure the venturi
tube slides onto the main burner orifice.
Step 16. Reinstall the two 5/16 in. screws removed in Step 2.
