ORIFICE CONVERSION
1. From Natural Gas To LP/Propane Gas:
a. Change the appliance pressure regulator from
natural to LP setting. (See figures 10, 11 or 12).
b. Screw the burner orifice hoods down tight against
the pins. (See figure 13B). Use care to not over
tighten. Over tightening can damage the coaxial
pin inside the orifice hood.
NOTE: On units using Eaton Oven Safety Valve,
screw the valve orifice hood down tight against the
valve body. (See figure 13D). It is important that
the hood be turned down as far as it can go to
insure that complete conversion has occurred.
c. Adjust burner air shutter to the widest opening that
will not cause the flame to lift or blow off the burner
when cold.
NOTE: Correctly adjusted sealed burners, can
have flames that will lift or blow without a pot over
the burner. These should be adjusted with a pot in
place.
2. From LP/Propane Gas To Natural Gas:
a. Change the appliance pressure regulator from LP
to natural setting. (See figures 10, 11 or 12).
b. Screw the burner orifice hoods away from the pins.
(See figure 13A). Approximately 1 1/2 to 2 turns.
NOTE: On units using Eaton Oven Safety Valve,
screw the burner orifice hoods away from pin (see
figure 13C). Approximately 1 1/2 to 2 turns.
c. Adjust burner air shutter to the widest opening that
will not cause the flame to lift or blow off the burner
when cold.
NOTE: Correctly adjusted sealed burners, the
flame will lift or blow without a pot over the burner.
These should be adjusted with a pot in place.
