C. General Maintenance and Cleaning
1. Types of Fuel
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
(Figure 19.1)
. A clinker is formed when dirt, ash or a
non-burnable substance is heated to 2000°F (1093°C)
and becomes glass-like. See
Section C. High Ash Fuel
Content Maintenance on page 15
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.
3. Ash Removal from Firebox
• Frequency:
Weekly or more frequently depending on
ash build-up
• By:
Homeowner
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.
See Disposal of Ashes.
4. Cleaning Ash Drawer
• Frequency:
Weekly or every 5 bags of fuel
• By:
Homeowner
Empty into a non-combustible container and re-install ash
drawer.
See Disposal of Ashes.
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.

NOTE:
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.
c. If rod is hard to pull, it may be necessary to use your
fire pot clean-out tool to chip 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.
d.
The fire pot floor plate must be fully closed when
finished
(Figure 19.2).
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.
