9. Cleaning the Hopper
• Frequency:
Monthly or after burning 50 bags of fuel or
when changing fuel type
• By:
Homeowner
After burning approximately 1 ton of fuel you will need to
clean the hopper to prevent sawdust build-up.
A combination of sawdust and pellets on the auger reduces
the amount of fuel supply to the fire pot. This can result in
nuisance shutdowns and mis-starts.
a. The appliance must be in complete shutdown. Allow
the appliance to completely cool down.
b. Empty the hopper of any remaining pellets.
c. Vacuum the hopper and feed tube.
8. Cleaning the Exhaust Path
• Frequency:
Every 25 bags or monthly or more frequently
depending on ash build-up.
• By:
Homeowner
a. Appliance must be completely cool.
b. Open cast hinge face. Remove baffle and right
brick and thoroughly vacuum the area and continue
throughout the rest of the firebox.
c. Replace right brick and baffle and close cast
hinge face.
7. Cleaning Beneath Heat Exchanger
• Frequency:
Monthly or after burning 1 ton of fuel
• By:
Homeowner
a. Be sure the appliance is allowed to cool, has been
unplugged and the exhaust blower is off.
b. A more thorough cleaning is needed to remove the
excess ash that is left behind from the use of the
cleaning rods for the heat exchanger tubes.
c. The ash will be resting on the back of the baffle. This
will require removing the baffle. Refer to
Baffle
on
6. Cleaning Heat Exchanger Chambers & Drop Tube
• Frequency:
Monthly or every 1 ton of fuel
• By:
Homeowner
The amount of ash buildup in the fire pot will be a good
guide to determine how often you should clean the
heat exchangers.
a. Allow the appliance to completely cool down before
pulling the cleaning rods. Turn the thermostat on and
then immediately off to start the exhaust blower on its
cycle time. It will pull fly ash out the exhaust instead
of into the room.
b. Locate the 2 exposed rods directly underneath the
heat exchanger tubes
(Figure 20.1)
.
c. To clean, pull the rods straight out until it stops,
approximately 8 inches (203mm). Slide the rods OUT
and IN a couple of times.
5. Disposal of Ashes
• Frequency:
As needed
• By:
Homeowner
Ashes should be placed in a steel container with a tight-
fitting lid. The container of ashes should be moved outdoors
immediately and placed on a non-combustible floor or
on the ground, well away from all combustible materials,
pending final disposal.
If the ashes are disposed of by burial in soil or otherwise
locally dispersed, they should be retained in the closed
container until all cinders have thoroughly cooled. Other
waste shall not be placed in this container.
Disposal of Ashes
• Ashes should be placed in metal container
with tight fitting lid.
• Ashes should be retained in closed
container until all cinders have
thoroughly cooled.
