maintenance
CAUTION: Cleaning of the heat exchangers, flue pipe,
chimney, and combustion blower fan, is especially
important at the end of the heating season to minimize
corrosion during the summer months, caused by
accumulated ash.
The tabs go into the slots on the baffle and the latch flips
downward to seal at the angle. Lift the latch and lift the baffle
off of the tabs for removal. Ashes from the heat exchange
tubes can be cleaned from this area. Sliding the firebrick
from one side to the other will allow more space for baffle
removal.
Cleaning
To maintain maximum heating efficiency, this cleaning
should be performed weekly during the burn season. The
frequency of this cleaning will be directly related to the quality
and quantity of fuel being consumed. Keep in mind that the
cleaner the heat exchanger tubes are kept, the higher the
heat transfer efficiency will be.
Due to the ease of restarting, it is recommended that the
boiler be turned
OFF
for an hour before cleaning.
Start by removing the two firebox baffles as shown above, then
reinstall the ash pan. Next, remove the top heat exchanger
cover to expose the heat exchanger tubes. Vacuum this upper
exhaust chamber. Some of the tubes contain a spiral baffle
which you can use as a cleaning device. Simply work the
spiral up and down, approximately 6 inches, to scrape the
inside surface of the heat exchange tube(s). The removed
debris will fall to the ash pan and on the angled chamber of
the firebox. Once all tubes are cleaned, remove the ash pan
and clean the remainder from the angles.
With a wisp brush, paint brush or a soot vac, clean the firebox
walls and any fly ash that has accumulated in the burnpot,
or burnpot opening. At this time you can scrape and clean
the burnpot and fines cleanout area.
Inspect all sealing gaskets to ensure a proper seal and re-
install all components removed for cleaning.

Firebox Baffle Removal
Note: The firebox baffles (#1-10-232052) are considered
to be a consumable item. Check for signs of warping or
damage, and replace if necessary.
CAuTION: For your safety, do not vacuum hot ashes or
embers. Some portions will remain hot, long after shut-
down. wear gloves to protect skin from burns.
Install the Cleanout Cover Lift Handle by using the spring latch
holes. Install one end of the Cleanout Cover Lift Handle into the
back spring latch hole while the other side gets placed into the one
positioned on the opposite side as pictured below.
Pull upward slowly
After the Clean Out Cover has been removed you can now remove
the spirals. Using the Spiral Removal Tool, clamp through the
opening located at the top of each spiral and slowly pull upward
as shown below.
