column:
1. Make sure there is no pressure in the boiler
during the removal of the probes.
2. Remove one probe (using a 7/8” socket), clean
with very ne emory cloth and replace it before
removing another to assure no probe mix-ups

Flame Scanner Adjustments for
Fulton Gas Fired Steam Boilers
Flame detector adjustments are made with the
detectors installed and the burner running. It is essential
to obtain optimum ame signal detection for safe and
continual operation of the control relay
If a detector is inoperable, it may prove the detector is
working and only an adjustment to the ame is needed
to improve the signal.
If the detector is found to be defective, replace.
Adjustments to establish a good signal may include the
following:
• Air damper adjustments in the combustion settings.
• Adjusting gas pressure through the gas regulator.
