WARNING
Extreme caution must be exercised
when checking a failing transformer.
They are capable of producing very
high voltages which may result in
personal injury and death.
3. With microampmeter in place, turn power to the panel ON.
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 orifi ce plug into
the scanner eye area.
5. Repeat steps 1 - 3 until a reading of #1 or less is achieved on the
microampmeter.
6. Turn power OFF. Hook the wire up again, and turn power ON. Start boiler
to ensure the safety light is off .
Procedure for Removing/Cleaning the Burner
Perform the following steps:
1. Remove all bolts that connect the transition elbow to the burner plate, and
to the scroll tube.
2. Pull burner out of unit by fl ange.
3. Inspect burner and wipe off (do not scrub or use wire brush) any soot or
foreign material that may have accumulated. If available, use compressed
air to clear the burner. Wipe out the inside of the burner with a clean cloth.
4. Reverse removal steps for reinstallation of the burner assembly.
5. Test fi re the boiler and use a combustion analyzer to ensure that the fuel/
air ratio is set correctly throughout the range. Refer to the Fulton factory
test fi re sheet for combustion settings.
Procedure for Soot Cleaning
Perform the following:
1. Determine if fl 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 fl 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 fl ue cover plates.
3. Using a wire brush, carefully remove soot from fl 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.
6. Replace clean-out plug carefully so as not to damage insulation.
