Appendix D: Maintenance
/e Alternate Heating Systems Coal Gun
TM
is
designed to provide years of reliable service.
Nevertheless, it is necessary to provide basic service
in order to maintain optimum eIciency and service
from your boiler. We recommend that you have your
authorized Alternate Heating Systems dealer provide
the seasonal preventative maintenance service. If
you decide to provide your own maintenance, the
instructions provided here are to be used as a guide.
Routine maintenance should be performed every
three months on units in continuous operation and
at least once each heating season on residential
installations.
Before the boiler is serviced, shut oD power to
the boiler. /e coal 1re must be completely out. If the
boiler has been actively 1ring, it may take days for
the 1re to go out completely. Make sure the coal pot,
boiler and ash grate are cool.
END OF SEASON CLEANING
Seasonal maintenance of the Coal Gun is simple
but critical to maintaining top performance and
longevity. To clean safely, wait until the 1re has gone
out and ash and water temperatures have cooled to
ambient temperature. If in the process of cleaning
you encounter hot ash or evidence of a still burning
1re, stop and wait as long as needed to be sure the
1re is extinguished and everything has cooled
completely.
Cleaning Exhaust End of Swirl Tube
/e swirl tube heat exchanger vents into the ash
removal cyclone just under the opening for the @ue
connecting pipe. To access this area, disconnect your
@ue pipe from the top of the boiler. With the pipe
removed, loosen the nuts on the Flue Tube Assembly
@ange as seen in the following photo.

When all the nuts are removed, the @ue tube
assembly can be removed as shown below. In come
cases, it will be necessary to pry the @anges apart
using an appropriate tool.
Lifting Out the Flue Tube Assembly
Set the Flue Tube Assembly aside and look down
into the cyclone ash separator. You will see a square
hole located where the boiler swirl tube exits into
the cyclone. You can safely insert brushes and or a
vacuum hose for cleaning through this port. Fly ash
built up just inside this port will restrict air@ow and
