C. General Maintenance
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, 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 section on
High Ash Fuel Content
Maintenance
on
in this section for more
details on fuels with high ash content.

2. Cleaning Firepot with Cleaning Rod & Firepot
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 appliance.
b.
Locate the fire pot cleaning rod on the right side
of the appliance
(Figure 16.2)
. When you pull the
cleaning rod straight out it will slide open the firepot
floor to allow the ashes to be deposited in the ash
drawer. You will see the light color painted area on
the cleaning rod to let you know the rod is in OPEN
position
(Figure 16.3)
.
c.
Pull the firepot cleaning rod OUT and IN a couple
of times to help shake debris loose. If the rod is
hard to pull, it may be necessary to use your firepot
clean-out tool to chip away material that has built
up on the bottom plate of the firepot and to push
out any clinkers while in the open position.
d.
To close the firepot floor:
slightly raise the cleaning
rod and then push it back into place. If you have
closed the cleaning rod properly (pushed all the
way in) you will not see any of the light color
painted area
(Figure 16.3)
.
e.
Always have the ash drawer in place before pulling
the fire pot cleaning rod, otherwise the ashes will
fall down and fill the outside air opening and the
appliance will produce soot out of the exhaust and
will affect efficiency.
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. 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.
Vacuum out the firebox thoroughly on both sides
of the firebox and the floor and ceiling. 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. See section
on
Disposal of Ashes
c.
Always have the ash drawer in place before pulling
the fire pot cleaning rod, otherwise the ashes will
fall down and fill the outside air opening and the
appliance will produce soot out of the exhaust and
will affect efficiency.
