WARNING: Failure to position the parts in accor-
dance with these diagrams or failure to use only
parts specifically approved with this heater may
result in property damage or personal injury.
Replace Pilot Orifice
1. The pilot hood is held in place by spring pressure.
Remove the hood by pulling it directly up from the
pilot bracket. (Fig. 43)
2. Insert a 3/32” (4mm) Allen wrench into the hexago-
nal keyway of the injector (Fig. 43) and rotate it
counterclockwise until it is free of the injector jour-
nal. (Fig. 43)
4. Insert the Allen wrench into the end of the injector.
Insert the injector into injector journal, and rotate the
injector clockwise until a torque of 9 in/lbs. is
achieved. Replace the pilot hood by aligning the tab
on the base of the hood with the slot in the side of
the pilot journal. Push the hood down, directly onto
the pilot bracket. (Fig. 43) The hood must sit
squarely on the bracket for proper operation. Check
to insure the hood is properly seated onto the pilot
bracket.
Convert Valve to LP
1. Using a Torx T20 bit or slotted screwdriver, remove
and discard the three (3) pressure regulator mount-
ing screws (A), pressure regulator tower (B) and
diaphragm (C). (Fig. 45)
2. Insure the rubber gasket (D) is properly positioned
and install the new HI/LO pressure regulator assem-
bly to the valve using the new screws (E) supplied
with the kit. Tighten screws securely. (Fig. 46)
3. Install the enclosed installation label (F) to the valve
body where it can easily be seen.
4. Apply gas to system and relight appliance according
to manufacturer’s instructions.
5. With the main burner “ON”, test the new pressure
regulator assembly for leaks using a soap solution.
