CAUTION
Do not turn the screw excessively in the
counterclockwise direction. The screw can
become loose and fall out resulting in a gas leak.
2. Rotate the screw clockwise to decrease and
counterclockwise to increase the flame height.
OVEN PILOT LIGHT
Figure 27: Inline Pilot Adjustment Valve
A. Inline Pilot Adjustment Valve
B. Gas Shutoff Valve
The pilot flame should be:
A. Large enough to completely engulf the tip of
the thermocouple/sensor and make the tip of
the thermocouple/sensor red hot.
B. A sharp, well-defined two-tone blue flame
when burning natural gas.
NOTE:
When burning propane (LP), there may be
a tiny yellow tip to the flame. This yellow tip should
be no more than 10% of the total flame size.
AIR SHUTTER ADJUSTMENT
The efficiency of the burners depends upon a
delicate balance between the air supply and the
volume of gas. When this balance is disturbed,
poor operating characteristics and excessive gas
consumption will occur.
An air shutter on the front of each burner controls
the air-gas mix. With natural gas, the air shutter
will be approximately 50% open. On propane (LP)
the air shutter will be approximately 90% open.
If the flame is soft, lazy, or yellow:
There is not enough primary air. To correct this
condition, rotate the air shutter open until the
burner flame begins to lift from the burner, and
then close the shutter slightly. If this does not
solve the problem, check the burner for
obstructions and clear as necessary.
If the flame is lifting off the burner:
There is too much primary air. Close the air shutter
slightly and retest.
Note:
If grates, hot tops or oven bottoms have been
removed to make shutter adjustments, recheck flame
characteristics with these items in place.
If burner operation still seems poor and other
systems have been checked, refer to NOZZLE
AND ORIFICE CHECK.
