1.Types of Fuel

Depending on the type of fuel you are burning will dictate how often the firepot 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 firepot system will routinely clean the firepot, at shutdown when the wall control is satisfied or the predetermined amount of burn time has elapsed.

3.Cleaning Ash Pan

•Frequency:

Wood Pellet Fuel: Weekly or every 5 bags of fuel

Alternate Fuel: Daily

•By: Homeowner

Locate the ash pan underneath the firepot. Slide the ash pan straight out. Empty into a non-combustible container and re-install ash pan. When replacing ash pan push it back until it catches on the 2 side latches.

See Disposal of Ashes below.

A clinker is formed when dirt, ash or a non-burnable substance is heated to 2000°F (1093°C) and becomes glass- like. Clinkers filling 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 31.1.

2.Auto-Clean System Inspection

•Frequency: Monthly or more frequently depending on fuel type

•By: Homeowner

a.The appliance must be in complete shutdown, completely cool and the exhaust blower off.

b.Inspect the auto-clean springs 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 floor it means the springs have lost their tension and can not keep the floor in the proper position.

This will cause ignition problems and fuel falling into the ash pan. Replace them if that occurs.

c.Inspect the holes in the firepot floor for any debris. They must be kept clear. If you are burning corn, the holes have a tendency to fill with particles which will need to be removed.

4.Ash Removal from Firebox

•Frequency: Weekly or more frequently depending on fuel type or ash build-up.

•By: Homeowner

There must not be any hot ashes in the firebox during cleaning so allow the appliance to completely cool. 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.

WARNING

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.

5.Disposal of Ashes

•Frequency: As needed

•By: Homeowner

Ashes should be placed in a metal container with a tight-fitting lid. The closed container of ashes should be 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 been thoroughly cooled.
