:
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION.
A Qualified Service Technician or Installer must set the Slider Damper.
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 slider damper knob is located on the left cab side (see Figure 5).
Figure 5: Slider / Damper Knob.
• 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). If this happens, pull the Slider / Damper out slightly to increase the
air flow to the fire.
