an aqua stat. Turn the dial 20° past the boiler water
temperature. Use an ohmmeter to test the terminals
for continuity. If the contacts are closed before you
turn the dial it should open a9erward. If it is opened
before you turn the dial it should be closed
a9erward. It can be common that the contacts
engage or dis/-5° from the reading of the
temperature gauge due to slow water circulation in
the boiler vessel. If the temperature di:erence is
more than +/-5° than the aqua stat should be
replaced. If there is a discrepancy in the
temperatures, be sure that the temperature gauge is
accurate.
is can be done by testing the boiler water
temperature with a second thermometer or
temperature gauge.
GENERAL CHIMNEY REQUIREMENTS
If the chimney must go through a combustible
wall, be sure to use a metal thimble specially
designed for this purpose.
e proper way to install a
thimble is to cut an oversize hole in the sheetrock
about 6 or 7 inches larger than the thimble. However,
be sure to follow the manufacturer’s directions that
come with the thimble. A metal ring shield is used to
cover the hole.
is way air can circulate and cool
the area around the passageway.
Specific Chimney Requirements for the
Wood Gun™
e Wood Gun™ creates its own dra9; therefore
having su<cient height in the chimney is not an
issue. Excessive chimney height can allow for more
cooling of exhaust gases and lead to condensation
issues. Other aspects of chimney construction that
lead to condensation include use of a masonry
chimney that lacks an insulated liner. Having such a
chimney on the outside of the house compounds this
problem as well. Because of the high e<ciency of the
Wood Gun, and resultant low stack temperatures, it
is important to try to preserve exhaust heat. Always
check with your local building inspector and
insurance agent to assure compliance.
Stovepipe should be sized as follows:
✔
E100 to E180: not less than 6 IN diameter.
✔
E250 to E500: not less than 8 IN diameter.
Never decrease the cross-sectional
area of the stovepipe/chimney
because the velocity of the exhaust
will increase thus increasing the
likelihood of particle discharge in
the exhaust
Using larger diameter stovepipe is generally not a
problem. It is a good practice to run as long a vertical
pipe as you can, coming o: of the cyclone. You will
want to avoid having an elbow or “T” immediately
above the cyclone. Provision must be made for
disassembly and cleaning. Excessive weight of pipe
placed on the cyclone must be avoided. Utilize
ceiling, roof or other supports to avoid adding too
much weight to the top of the cyclone.
Never use a prefabricated chimney
connected directly to the ash
recovery cyclone and leading to the
outside without any elbows or
cleanout T-joints.
Having adequate combustion air is critical to
boiler performance. is means that there must be
either enough air in ltration to supply the boiler
with combustion air, or other means must be put in
place to provide this makeup air.

doors and windows. In well-insulated homes it may
be necessary to provide additional outside air into
the home. It is possible to duct outside air directly to
