C. General Maintenance and Cleaning
1.
Types of Fuel
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, it
may be necessary to clean the fire pot more than once a
day.
Dirty fuel will cause clinkers to form in the firepot
(Figure 18.1)
. 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 Fuel Content
Maintenance
for more details on different types
of fuels.

need to unplug the insert.

Ash Removal from Firebox
• Frequency:
Every 5 bags or 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.
The firebox ash should be removed every time the
exhaust path is cleaned. 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. Remove ash with an ash vacuum or whisk
broom and small dust pan.
d. This ash is deposited in the same ash pan as the fire
pot debris. The ash pan should be emptied every time
you clean the firebox. Remember to place the ash
and debris into a metal or noncombustible container.
e. The cleaning rods must be fully closed when cleaning
is complete; see
Disposal of Ashes
4.
Cleaning Ash Pan
• Frequency:
Weekly or every 5 bags of fuel
• By:
Homeowner
Empty into a non-combustible container and re-install ash
pan; see
Disposal of Ashes
on
b. Pull fire pot cleaning rod OUT 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 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 18.2)
.
