2. Ash Removal from Firebox
• Frequency:
Weekly or more frequently depending on
ash build-up
• By:
Homeowner
Be sure the wall control screen says OFF and the
appliance is allowed to cool.
There must not be any hot ashes in the firebox during
cleaning.
Frequent cleaning of the ash in the firebox with a vacuum
cleaner will help slow down the build-up of ash in the
exhaust blower and vent system.
3. Cleaning Ash Pan
• Frequency:
Weekly or every 3-5 bags
• By:
Homeowner
a Locate the ash pan underneath the firepot.
b. Slide the ash pan straight out.
c. Empty into a non-combustible container and re-install ash
pan.
d. When replacing ash pan push it back until it catches on
the 2 side latches.
e. Clinkers filling the ash pan will have to be cleaned out
more often than ash.
See Disposal of Ashes.
4. 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 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.
WARNING! RISK OF FIRE!
Keep combustible materials,
gasoline and other flammable vapors and liquids clear of appli
-
ance.
• Do
NOT
store flammable materials in the appliance’s vicin
-
ity.
• Do
NOT
use gasoline, lantern fuel, kerosene, charcoal lighter
fluid or similar liquids to start or “freshen up” a fire in this
heater.
Keep all such liquids well away from the heater while it is in use
as combustible materials may ignite.
WARNING! RISK OF FIRE!
Do
NOT
store fuel:
• Closer than required clearances to combustibles to appli
-
ance.
• Within space required for loading or ash removal
.
C. General Maintenance and Cleaning
1. Auto-Clean System Inspection & Cleaning
• Frequency:
Monthly or every ton (aprx. 50 bags) or
more frequently depending on the type of fuel
• By:
Homeowner
a. Be sure the wall control screen says OFF and the
appliance is allowed to cool.
b. Open the firebox door. Inspect the auto-clean springs:
Fig. 23.1
c. Inspect the holes in the firepot floor for any debris.
• The holes must be kept clear.
d. How often the firepot cleans itself depends on:
• The type of fuel you selected on the thermostat wall
control
• How long the appliance burns before satisfying set point
on wall the control.
• Burning biomass fuels may require a more thorough
cleaning during the burn season.
e. Excessive clinkers will eventually jam the auto-clean
system and generate an error message on the wall
control.
• Inspect for any degradation or deformation
• As the springs heat up and cool down they can lose
tension
• If there is a gap showing above the firepot bottom,
approximately 1/16 inch (1.59mm) or more, it means
the springs have lost their tension
• Lost tension can not keep the floor in the proper
position causing ignition problems and fuel falling into
the ash pan.
• Call your dealer to replace the springs.
