B. General Maintenance and Cleaning
1. Types of Fuel
Depending on the type of fuel you are burning will dictate
how often you have to clean your fire pot.
If the fuel you are burning has a high dirt or ash content or
you are burning shelled field corn, it may be necessary to
clean the fire pot more than once a day.
Dirty fuel will cause clinkers to form in the fire pot. A clinker
is formed when dirt, ash or a non-burnable substance is
heated to 2000°F (1093°C) and becomes glass-like. See
page 34 in this section for more details on fuels with high
ash content.
2. Cleaning Fire pot with Cleaning Rod & Fire pot
Clean-Out Tool
•
Frequency: Daily or more often as needed
•
By: Homeowner
a. The appliance must be in complete shutdown and cool
and the exhaust blower off. If you are just cleaning the
fire pot, there is no need to unplug the insert.
b. Pull fire pot cleaning rod OUT and IN a couple of times
to help shake debris loose. If rod is hard to pull, it may
be necessary to use your fire pot clean-out tool to chip
f i r e - p a r t s . c o m
away material that has built up on the bottom plate
of the fire pot and to push out any clinkers. Larger
clinkers may have to be removed from the top of the
fire pot. Corn clinkers can be especially difficult to
break up.
c. The fire pot floor plate must be fully closed when
finished (Figure 19.1).
WARNING
Fire Risk.
•
NEVER pull fire pot cleaning rods or
cleaning slide plates when appliance is
operating. Hot pellets may fall into ash pan
and may start a fire or have mis-starts due
to lack of vacuum.

a. There must not be any hot ashes in the firebox during
cleaning so allow the appliance to completely cool.
Frequent cleaning of the ash in the firebox will help
slow down the build-up of ash in the exhaust blower
and vent system.
b. Plug in your appliance, if unplugged, and turn the
thermostat on and immediately shut it off to start the
exhaust blower on its cycle time. It will pull fly ash out
the exhaust instead of into the room.
c. Open door. There are 2 cleaning slide plates to the
left and right of the fire pot with finger holes. Pull both
slide plates out and sweep the remaining ash from the
firebox into the 2 open holes. A paint brush works well
for this. Close slide plates.
d. This ash is deposited in the same ash drawer as the
fire pot debris. The ash drawer should be emptied
every time you clean the firebox. Remember to place
the ash and debris into a metal or non-combustible
container.
e. The 2 cleaning slide plates must be fully closed when
cleaning is complete.
4. Cleaning Ash Drawer
•
Frequency: Weekly or every 5 bags of fuel
•
By: Homeowner
Locate the ash drawer underneath the fire pot and slide
the ash drawer straight out. Empty into a non-combustible
container and re-install ash drawer.
WARNING
Fire Risk.
•
The cleaning slide plates must be fully
CLOSED when appliance is operating. Hot
pellets may fall into ash pan and start a fire.
5. Disposal of Ashes
•
Frequency: As needed
•
By: Homeowner
Ashes should be placed in a metal container with a tight-
fitting lid. The closed container of ashes should be placed
on a non-combustible floor or on the ground, well away
from all combustible materials, pending final disposal.
If the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the closed
container until all cinders have been thoroughly cooled.
WARNING
Disposal of Ashes.
•
Ashes should be placed in metal container
with tight fitting lid.
•
Ashes should be retained in closed
container until all cinders have thoroughly
cooled.
