SLIDER/DAMPER INSTALLATION INSTRUCTIONS
This is used to regulate the airflow through the pellet stove.
A Qualified Service Technician or Installer should set the Slider Damper.
The Slider Damper has been pre set at the factory. However, during installation this slider damper might require
further adjustment depending on type of installation or fuel quality.
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 knob,(Dial a Fire). This
blower will decrease the vacuum pressure inside the stove and as the heat output knob is turned up. The vacuum
pressure inside the firebox will increase as the combustion exhaust blower increases in speed.
If the fire should happen to go out and the Dial A Fire 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 over flows the burn pot or there is a build up of clinkers This
would be a sign that the pellet quality is poor and 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 see the characteristics of the fire.
•
A tall and lazy flame with dark orange tips requires more air – Open slider / damper up.
•
A short and brisk flame, like a blowtorch, has too much air – Close slider / damper down.
•
If the flame is in the middle of these two characteristics with a bright yellow/orange, active flame 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.
