4. During the ignition trial period, determine if the microampmeter exceeds
#1. If yes, it is likely picking up ignition interference and realignment is
necessary. It may be necessary to place a reduced scanner ori ce plug into
the scanner eye area.
5. Repeat steps 1 - 3 until a reading of #1 or less is achieved on the

air ratio is set correctly throughout the range. Refer to the Fulton factory
test re sheet for combustion settings.
Procedure for Soot Cleaning
Perform the following:
1. Determine if ues are dirty by checking stack temperature with a stack
thermometer. If temperatures are in excess of 600 F (315 C) while the boiler
is operating, the ues are likely dirty/restricted in some other manner.
NOTE: Usually soot cleaning is performed annually, unless the burner setting has
been altered and excessive soot has been produced as a result.
2. Remove burner and ue cover plates.
3. Using a wire brush, carefully remove soot from ue passages.
4. Clean out plug at lowest part of unit and clean passages between ribs and
bottom of combustion chamber.
5. Remove all soot with a vacuum cleaner. This may be carried out from the
top and via the inspection doors at the bottom.
