PILOTS:
Units With Standing Pilots
The pilot adjustment is part of the combination control valve located just behind the lower front access door. It
is located just to the left of the pilot tube on the inlet (top) side of the gas valve. (See wiring diagram or
pictures.) Remove the large screw on the left side of the pilot tube outlet. Below this screw is a slotted
adjustment screw.
The front burner shield should be removed to see the pilot. The pilot should be adjusted to a blue flame with a
slightly yellow tip capable of keeping the safety control open.

Replace the burner shield and screw after adjustment.
Units With Electronic Ignition
The pilot adjustment is part of the combination control valve located just behind the lower front access door. It
is located on the center left side of the control (see wiring diagram or pictures), just below the large slotted
screw head. Remove the large slotted screw; below this is a second slotted adjustment screw.

THERMOSTAT:
The thermostat adjustment should not be changed. Check the following before changing the thermostat:
1.
With kettle cold, the pressure on the pressure gauge should read 25 to 30 inches mercury column vacuum. If
not, see " Re-establishing Vacuum" section.
2.
The pressure switch is not set too high or too low and causing the out of adjustment condition. A voltmeter
should be used by a properly trained serviceman to determine if the pressure switch or thermostat is actually
cycling the burners. If the pressure switch is found to be the problem, see "Pressure Switch" section.
