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.
DAILY MAINTENANCE
• Surfaces on the front of the stove will be extremely
hot during operation. Always wear heat resistant
gloves to perform periodic maintenance.
• Remove heat shield. Using a wooden stick, tap the side
heat exchangers that are located on the left and right
sides of the firebox. When you open the door, they are
located directly inside to the left and right. When you
tap the sides with the wooden stick the loose fly ash will
drop out of these holes.
• Inspect inside stove for excessive ash build up. You will
learn some fuels produce more ash than others.
WEEKLY MAINTENANCE
• 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. Remove the exhaust pipe from the back of the
stove and remove any ash that may have collected in
the pipes. Replace the pipes to the stove and seal with
high temperature seal tape. If you have installed proper
clean out tees you will not have to take the chimney
sections apart.
NOTE: A clean unit bums efficiently and will remain
trouble free!
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
any ash 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 firebox area.
When the unit is cleaned out, empty the hopper, take the
venting apart and clean out the fly ash, rinse and let dry.
Take the draft blower off and clean out all areas such as
back heat exchanger and lubricate the auger, auger tube,
and fire pot area. (Something like vegetable spray works
great to coat the inside of the unit and the moving parts).
Clean the glass, doors and outer cabinet so that you are
ready for the next heating season. Use of a wet/dry vacuum
makes the clean out easier and faster.
