Maintaining the Heater

Proper maintenance of the heater is important to
insure reliable, efficient and safe operation of the
heater. Proper maintenance will also help insure longer
service life of the heater. There are weekly, monthly
and end of season maintenance procedures which need
to be understood and followed.
9.1 Weekly Maintenance
9.1.1 Fire Chamber Ash Bed.
During normal use ash will accumulate along the
bottom sides of the fire chamber. If left untouched this
ash will pile up high enough to plug the primary air
delivery holes. This ash needs to be stirred and moved

away from the walls and primary air holes regularly
using the Large Ash Tool (Section 8.1). If the ash at
the bottom of the fire chamber builds up more than
3-4 inches the access ash should be removed with the
ash shovel. When removing ash always leave at least 2
inches of ash at the bottom of the fire chamber. This
helps protect the fire brick from damage during the
wood loading process. (Review diagram 9.1-Primary
Fire Chamber Ash Removal)
9.1.2 Secondary Chamber Ash Removal
During normal use ash will build up in and around
the secondary burn chamber and needs to be removed
periodically.
IMPORTANT!
Weekly, run the Large
Ash Tool along the
bottom sides of the
firechamber to break
up the ash. Move the
ash away from the sides
and towards the middle
of the firechamber.
