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 slider damper should be set only on a hot
stove (operating for thirty (30) minutes or more) by placing
a Magnahelic Pressure Gauge in the firebox. The reading
can be taken from the ⅛” (3 mm) hole located in the front
of the firebox under the door (see Figure 42). 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.

:
Due to fuel quality the slider damper and control board trims
may need to be fine-tuned.
• 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.
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.
