INITIAL SETUP
1
2
Slide open or close the damper as needed to obtain a
fire that is brisk enough to carry ash out of the grate, but
not so brisk that it carries whole pellets out as well; this is
known as popcorning.
Normally, you should find that the damper will need to be
1/4” to 1/2” open. This may vary with length of vent run,
pellet quality and elevation. The best way to set this is at
feed rate #4. Adjust the damper rod 1/8” at a time, letting
the stove burn for 1-2 minutes per adjustment, until pop-
corning ceases.
Popcorning is the result of incorrectly set air flow, causing fresh
unburned pellets (or barely ignited pellets) to be carried out of
the burn grate and into the ash bin by high air flow. This occurs
before more pellets have fallen into the burn grate (ie. It’s AIR
that carries the pellets out, not the impact of newly dropped
pellets. See SPARKING). A pellet that has been ‘popcorned’
out of the burn grate can glow for anywhere from several
seconds to several minutes.

AIR INLET DAMPER
DEFINITIONS
POPCORNING
Sparking occurs from the impact of fresh pellets being dropped
into the burn pot and knocking parts of burning pellets out. Also,
the natural burning of wood can create sparks. Sparks will glow
in the ash bin generally for several seconds before burning out.
SPARKING
PLEASE NOTE:
Sparking is normal. Popcorning can be
remedied by following step 2 above.
It is critical for the correct operation of your stove that the burn grate, air
inlet damper, combustion fan speed and fuel rate be set correctly!
START THE APPLIANCE AS PER THE LIGHTING INSTRUCTIONS.
The igniter light MUST be off in order to begin further adjustments; this
can take from 10-15 minutes to occur. Let the stove run until the
igniter light goes off, then push the START / FEED RATE button several
times until feed rate #4 LED lights up. Let stove run for 10-15 minutes.
Now you will adjust the air inlet damper. This will have to be set
because the factory must be able to accomodate a wide range
of installations and elevations as well as fuel length and quality.
