This is used to regulate the airflow through the pellet stove.
The slider damper is located behind the left side panel. To open the left side panel, undo the one screw
located in the upper front corner of the cabinet side between the louvers. Also loosen three screws down
the back of the side panel.The combustion exhaust blower is a variable speed blower controlled by the
heat output button. This blower will decrease the vacuum pressure inside the stove and as the heat
output button is turned down. The vacuum pressure inside the firebox will increase as the combustion
exhaust blower increases in speed (higher heat output setting).
The easiest way to make sure that an efficient flame is
achieved is to understand the characteristics of the fire.
• A tall, lazy flame with dark orange tips requires more
air – Open slider (pull out) slightly.
• A short, brisk flame, like a blowtorch, has too much air
– Close slider (push in) slightly.
• If the flame is in the middle of these two
characteristics with a bright yellow/orange, active
flame with no black tips then the air is set for proper
operation.
SPECIAL NOTES:
Pellet quality is a major factor in how the Pellet stove will
operate. If the pellets have a high moisture content or
ash content the fire will be less efficient and has a higher
possibility of the fire building up and creating clinkers
(hard ash build-up).

If the fire should happen to go out and the
heat output indicator has been set on the
lowest setting, the Slider Damper should be
pushed in slightly, decreasing the air in the
firebox.
If, after long periods of burning, the fire
builds up and overflows the burn pot or there
is a build up of clinkers, this would be a sign
that the pellet quality is poor, this requires
more primary air, the slider damper must be
pulled out to compensate. Pulling the slider
damper out gives the fire more air.
Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge can be used to set
the slider for best combustion.
The best settings are a reading of approximately 0.10 inches of
water column on the high fire setting. Some fuels may require higher or lower settings.
The
reading can be taken from the 1⁄8” (3 mm) hole located on the front of the unit below the door and behind
the magnetic ash lip.
