Hardwood Pellets: Weekly or every 3 bags
Alternate Pellets: Daily or every 1 bag
• By: Homeowner
a. The appliance must be in complete shutdown,
completely cool and the exhaust blower off.
b. It may be necessary to use your firepot clean-out tool
to chip away material that has built up on the sides of
the firepot and to push out any clinkers. Larger clinkers
may have to be removed from the top of the firepot.
Corn clinkers can be especially difficult to break up. If
the clinker adheres to the sides of the firepot, you will
need to manually clean the firepot.
c. After cleaning the firepot 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
finished.
