CAUTION
THIS IS A MINIMUM REqUIREMENT FOR SOOT
AND FLY ASH REMOVAL. ASHES SHOULD BE
PLACED IN A METAL CONTAINER WITH A TIGHT
FITTING LID. THE CONTAINER SHOULD BE PLACED
ON A NON-COMBUSTIBLE FLOOR, WELL AWAY
FROM COMBUSTIBLE MATERIALS, PENDING FINAL
DISPOSAL. IF ASHES ARE DISPOSED OF BY BURIAL
IN SOIL OR OTHERWISE LOCALLY DISPERSED, THEY
SHOULD BE RETAINED IN THE CLOSED CONTAINER
UNTIL ALL CINDERS ARE NO LONGER WARM.
• Complete the daily maintenance by checking the seal
on the doors. Look for pellets that may have been left
behind during loading. Check that each of the door seals
are flush with the stove and sealing properly.
WEEkLY MAINTENANCE
• The fire pot and the area around it are cleaned using the
special tool provided with the stove and the ash cleaning
vacuum. It is important to remove any unburned pellets
that may have fallen behind the burn pot.
• To clean the fire pot with the cleaning tool, remove the
fire pot by unscrewing the firepot cleaning rod from the
fire pot. Remove the rod and the firepott. Remove the fire
plate by lifting it out of pot holder (Figure 28). Brush all
of the ash from beneath the fireplate into the ash pan.
• Remove the ash pan and dump the ash into a metal
container.
• Cleaning of the exhaust system will depend upon the
ash and debris content of your fuel. If your fuel has a high
ash content and/or significant debris in it, the exhaust
system will require weekly cleaning. Cleaner fuels will
allow for monthly cleaning of the exhaust system. Clean
out tees in the exhaust system make this task much
easier.
NOTE: A clean unit burns efficiently and will remain
trouble free!
MONTHLY MAINTENANCE
• Remove the top baffle inside the firebox and clean
the fly ash and soot on all exposed parts using a steel
brush and ash cleaning vacuum. The use of a shop-vac
is not recommended. Talk to any authorized dealer for
information about the ash cleaning vacuum.
SEASONAL CLEANING
Once every year you must clean out all of the fuel in the
hopper, firebox area, ash pan and fire pot area. Corn and
pellets can accumulate moisture over the summer months
causing the unit to rust and the fuel to mold.
It is recommended that prior to shutting down the unit in
the spring it is run on the high setting for about six hours to
help clean out the heat exchanger system, venting system
and fire box area.
