:
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION. This is used to regulate the
airflow through the pellet stove.
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, refer to Figure 7.
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.
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).

UALITY
:
Due to fuel quality the slider damper and control board trims may need to be fine-tuned.
1. If the unit builds up on all settings, the slider damper rod should be pulled out in small increments to
give the unit more air.
2. If the unit has excesses ash build-up in the liner on the lower feed settings, the Combustion Blower
Trim should be increased one setting at a time until the problem improves (Factory Setting is #2).
3. If the fire is going out on low because the airflow is too great, the Combustion Blower Trim can be
lowered to the #1 setting.
4. If the stove has excesses ash build-up in the liner on the higher settings the Feed Rate Trim should be
trimmed down a setting at a time until the problem improves (Factory setting is #4).
5. If you need more heat and the fuel has long pellets, the majority are over 1” (2.5cm) in length, the
Feed Rate Trim can be moved up to the #5 setting. NOTE: Only do this if the fuel burns without
building up.
