Maintaining & Servicing Your Appliance
Figure 26.2 - Large Clinker
B. General Maintenance
1. Types of Fuel
Depending on the type of fuel you are burning will dictate how
often the fi repot cleans itself. If the fuel you are burning has
a high dirt or ash content or you are burning other biomass
fuels, it may be necessary to do a more thorough cleaning
during the burn season. The auto-clean fi repot system will
routinely clean the fi repot at shutdown when the wall control
is satisfi ed or the predetermined amount of burn time has
elapsed. A clinker is formed when dirt, ash or a non-burnable
substance is heated to 2000°F (1093°C) and becomes glass-
like. Clinkers fi lling the ash pan will have to be cleaned out
more often than ash. Excessive clinkers will eventually jam
the auto clean system and generate an error. Figure 26.2.
3. Cleaning Firepot with Firepot Scraper
• Frequency: As needed
• By: Homeowner
• Task:
a. The appliance must be in complete shutdown and cool
and the exhaust blower off.
b. It may be necessary to use your fi repot scraper to
chip away material that has built up on the sides of the
fi repot and to push out any clinkers. Larger clinkers
may have to be removed from the top of the fi repot.
Corn clinkers can be especially diffi cult to break up.
c, After scraping the fi repot and inspecting the holes, turn
off the power and then restore the power. The auto
clean system will then clean itself.
d. The firepot floor plate must be fully closed when
fi nished.
Shock and Smoke Hazard
• Proper Shutdown Procedure must be followed.
• Smoke spillage into room can occur if appliance
is not cool before unplugging.
• Risk of shock if appliance not unplugged before
servicing appliance.
CAUTION
A. Proper Shutdown Procedure
2. Auto-Clean System Inspection
• Frequency: As needed
• By: Homeowner
• Task:
a. The appliance must be in complete shutdown and
cool.
b. Inspect the auto clean rails for any degradation or
deformation. As the rails heat up and cool down there
may be some sagging of the rails. Replace them if
that occurs.
c. Inspect the holes in the fi repot fl oor for any debris.
They must be kept clear. If you are burning corn, the
holes have a tendency to fi ll with particles which will
need to be removed.
1. Set the thermostat wall control to “OFF” in AUTOMATIC/
MANUAL SETTINGS screen and let the appliance com-
pletely cool. Figure 26.1. The exhaust blower must be
off before you can unplug the appliance before servic-
ing.
2. Smoke spillage into the room can occur if the appliance
is not cool before unplugging.
3. There is a risk of shock if the appliance is not unplugged
before servicing the appliance.
