7. Change the Air Shutter position: Lift the shutter tube
up in its hinge pin slots and turn the tube over, so that
the appropriate fuel type indicator (LP or NG) is orient
-
ed facing you. See fig. 17. Push the shutter all the way
back over the burner orifice.
8. Change the Pilot Orifice. Pull the Pilot Hood off of
its base. It will snap by the retainer clip shown in Fig.
15. Using a 4 mm hex key, unscrew the pilot orifice.
Replace it with the orifice from the kit. Be sure the new
orifice is tightly secured to prevent gas by-pass leakage.
Replace the pilot hood. Use a small, spade screwdriver to pry
back the retainer clip and re-insert the head onto the base
.9. Reinstall the burner, engaging it within the air shut-
ter. BE CERTAIN THE BURNER IS LEVEL AND SECURELY
SEATED ON THE BURNER RETAINER. Properly located, it
should not be able to move to the right or left.
10. Replace the variable regulator on the gas control valve.
Remove the TruStart switch faceplate and move the
assembly out of the way to access the regulator. Using
a Torx T-20 screwdriver, remove the two screws from
the regulator tower on the front of the valve as shown
in fig. 18.
11. Remove the regulator tower and the rubber diaphragm.
12. Install the new regulator tower from the kit. Be sure
that the gasket is properly positioned and tighten
screws securely.
13. Apply the conversion notice labels to the appliance
so that they can be seen by any person that may be
servicing the unit.
• Label “A”: Apply to the floor of the valve compartment.
• Label “B”: Apply to the Rating Plate.
• Small valve sticker: Apply to valve body.

14. Use an electronic gas detector or soap solution
to test for leaks at the pilot head and all gas line
joints.
NEVER USE AN OPEN FLAME TO CHECK FOR
GAS LEAKS.
