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).
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.
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).
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.

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.
