Operating Instructions
The easiest way to make sure that an efficient flame is achieved is to understand the characteristics of
the fire.

:
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.
• 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, adjusting the air to fuel ratio.
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).
