Operating Instructions
For less experienced installers or owners a magnehelic gauge can be used to determine the proper
Damper setting. A magnehelic gauge will accurately measure the pressure in your firebox. There is a
small hole on underneath the ash lip on the right side of the firebox front, see figure 31. You
want a reading of .12-.15 WC (30-38 Pa) depending on pellet quality.
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 as the heat level output is decreased.
SPECIAL NOTES:
GUIDELINES FOR FINE-TUNING FOR FUEL QUALITY:
Due to fuel quality the damper and control board trims may need to be fine-tuned to achieve optimal
conditions.
1. If ash builds up in the unit 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 #3).
3. If the fire is going out on low because the airflow is too great, the Combustion Blower Trim can be
lowered one setting at a time.
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 #3).
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 increased.
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 silica ash build-up).
