CARE AND OPERATION
DAMPER OPERATION
The damper is a plate that helps control the amount of
airflow supplied for combustion. With the damper pushed
in all the way, the airflow is at its minimum.
damper is pulled out, more air is allowed to flow.
It is very important to preset your damper prior to burning
your pellet stove.
The Damper Control is located on the right side of the
stove. The damper should be pushed all the way in
toward the stove during initial operation. It may need
to be manually adjusted outward depending on the type
of pellet fuel being burned. The damper control adjusts
the amount of combustion air to the UltraGrate. When
the damper has been correctly adjusted, you will observe
a brisk, yellow-to-whitish flame. Fuel should not "pile-up"
in the grate. The proper air settings will vary from stove
to stove due to installation, altitude, and the fuel being
burned.

DAMPER ADJUSTMENT: 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 combus-
tion air; pull the damper out slightly and re-evaluate the
appearance of the flame. It may be necessary to con-
tinue this process, moving the damper outward incre-
mentally until proper combustion is attained (the flame
should become yellow and begin to "dance").
flame is "short" at the higher burn rates, or if the pellets
are burning up in the grate before new pellets are fed
into the fire, push the damper slightly inward and monitor
the flame. Continue the process of moving the damper
incrementally 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 pre-
vent the accumulation of ash in the grate.
DAMPER ADJUSTMENT GUIDELINE
Lack of Combustion Air: By opening the damper, this
will increase combustion air delivery. Symptoms of insuf-
ficient combustion air include; unburned fuel, lazy smoky
or red / orange flame, excessive ash or soot, excessive
buildup on glass, fuel may "pile-up."
Contributing factors:
•
High Altitude – Lack of oxygen
•
Restrictive Venting (elbows, horizontal runs,
cold external chimneys, etc.).
•
Dirty / Poor Quality Fuel.
Note: Excessive amounts of fly ash built-up in the grate,
clinkers in the grate or leakage of air (if the grate is not
properly seated) will starve the fire for air. See Routine
Maintenance, on pages 18 and 21 for information on
cleaning the stove.
Excessive Combustion Air: By closing the damper, this
will reduce combustion air delivery. Symptoms of excessive
air include; fuel burns too quickly (results in smoking or
smoldering pellets or pellets burn up before new pellets are
fed), white to yellow flame, etc. If the damper is open too
much, the burning pellets will lift off the grate and fly up
into the air much like popping corn does.
Contributing factor:
•
Venting system providing excessive draft.
Correct Combustion Air / Proper Burn Characteris-
tics: When the damper is correctly set, the burning pel-
lets should move (wiggle) around slightly and the flame
should be bright yellow and "dance."
Pellet Feed / Pellet Size:
The pellet feed system is designed to handle a wide
range of pellet sizes up to a maximum of 5/16" diameter.
Different pellets may feed at considerably different rates.
You may notice a difference in the burn if you change
pellet fuel sizes. The longer the pellet, the slower it will
feed and vice versa. If the stove will not stay burning at
the minimum fuel feed setting, those particular pellets
may not be feeding fast enough. If this happens, reduce
the amount of combustion air by adjusting the damper
(see Damper Adjustment on this page).
