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, 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 High Ash Content Maintenance
on page 22 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.
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 (See page 10).
— 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.
c. The fire pot floor plate must be fully closed when
finished (Figure 19.2).
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.

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.
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 (Disposal of Ashes on
page
20).
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.
