Flyash will deposit
along sections that
are horizontal
Make sure the cap is free of
debris (especially if it has a
screen that could become
blocked).
Check the vent sections for
creosote accumulation
(indicating a poorly burning
stove). Accumulation
greater than 1/4" must be
removed.
On vertically vented
systems, the dirtiest portion
is often the point where the
vent turns upwards (ex. the
"Tee"). Remove the clean
vent cover and inspect and
clean if necessary.
WHENEVER ANY PORTION OF THE PELLET VENT IS DISCONNECTED, THE JOINTS MUST BE
RE-SEALED WITH RTV 500°F SILICONE SEALANT.

WARNING
10.3.7 CLEAN THE VENT
10.4 IN THE EVENT OF A JAMMED AUGER
Occasionally damp fuel or foreign objects could get jammed in the auger screw. When this occurs it will be
necessary to empty the hopper and/or remove the auger screw from the hopper assembly.
Start by emptying the pellets from the hopper. Sometimes the object causing the auger screw not to turn will be
visible once the hopper has been emptied. If it is necessary to remove the auger screw start by removing both
of the side panels and the rear panel. Locate the auger motor, remove the set screw that secures the motor to
the auger screw. Remove the two hex bolts from the auger housing which will allow the auger screw to slide out.
After you have removed the shaft, inspect it for bent fl ights, burrs, or broken welds. Remove any foreign material
that might have caused the jam. Also, check the auger tube for signs of damage such as burrs, rough spots, or
grooves cut into the metal that could have caused a jam.
