for cleaning. Long handled brushes and the AHS
Swirl Tube Scraper are good tools to have ready at
hand for this. /e following photo shows the Swirl
Tube Scraper for the S130 Coal Gun in use. It
features a curved scraper head that matches the
curvature of the heat exchanger.
Swirl Tube Scraper
When you are 1nished scraping the surfaces,
vacuum the loose material out of the 1re tube and
swirl tube. In cases of severe build-up or neglect,
more than one scraping and vacuuming cycle may be
needed.
Vacuuming Heat Exchanger
When you are 1nished cleaning the rear of the
heat exchanger, reinstall the fan assembly to the
boiler. Use a bolt tightening pa ern as shown in the
following photo and no more than 15 – 20 lb-feet of
torque. Using too much torque will result in crush
damage to the ceramic heat shield.
Reinstall Fan Assembly
Remember that cleaning of the heat exchanger,
@ue pipe and chimney is especially important at the
end of the heating season to minimize corrosion
during the summer months caused by accumulated
ash. If your boiler is in a damp location, use any
means available to reduce moisture in the area and
humidity in the air. A heat source inside the 1re tube
of the boiler will help dry moisture inside the 1re
side and heat exchange surfaces. A piano heater or
40 wa incandescent rough surface light bulb are
good for this task. Any free moisture will readily
combine with residual @y ash and create sulfuric
acid. /is will cause rust and scale build-up on metal
surfaces exposed to this combination.
CLEANING COAL POT, FEED TUBE AND
GRATE
Remove and clean the ash pan. Remove
remaining coal from the hopper, coal pot and grate.
Examine all areas for damage and clean as needed.
Remove grate linkage arm and manually move grate
back and forth to check bearing condition.
Reassemble grate arm. Lubricate grate chain (if so
equipped) with chain oil and check sprockets for
wear.
Other routine maintenance items include:
•
Drive belts (belt drive units only) and roller
chains (if so equipped) should be inspected
and tightened if necessary. To adjust drive
belt tension and alignment, loosen motor
mount bolts (belt drive units only) and slide
motor so as to aDect proper tension and
