Damper Operation - All models:
The damper is a plate that helps control the amount of airflow
supplied for combustion. With the damper pushed all the
way in the airflow is at its minimum. As the damper is pulled
out, more air is allowed to flow.
It will be necessary to monitor the appearance of the flame
during the first 4-8 bags of pellets. If your flame is smoky
red/orange with evidence of soot at the top of the flame, you
need more combustion air; pull the damper out one notch
and re-evaluate the appearance of the flame. It may be nec­
essary to continue this process, moving the damper one
notch at a time until proper combustion is attained (the flame
should become yellow and begin to "dance"). If the flame is
"short'' at the higher bum rates, or if the pellets are burning up
in the grate before new pellets are fed into the fire, push the
damper in one notch and monitor the flame. Continue the
process of moving the damper one notch at a time and
evaluating the flame until proper flame appearance is
achieved.
Once the damper has been properly set it should not need
adjusting unless you are changing from a premium grade
pellet to a standard or high ash pellet, in which case the
damper may need to be pulled out to help prevent the accu­
mulation of ash in the grate.
Damper Adjustment Guideline
Lack of Combustion Air
Open damper more to increase combustion air delivery.
Symptoms of insufficient combustion air include; un­
burned fuel, lazy smoky or red/orange flame, excessive
ash or soot, excessive buildup on glass:
Contributing factors:
A. High Altitude - Lack of oxygen
B. Restrictive Venting (elbows, horizontal runs,
cold external chimneys, etc.).
C. Dirty/Poor Quality Fuel.
Excessive Combustion Air
Close damper more for less combustion air. Symptoms
of excessive air include; fuel burns too quickly (results in
smoking or smoldering pellets), white to yellow flame,
etc.
Contributing factor:
A. Venting system providing excessive draft.
