Guidelines For Fine-Tuning For Fuel Quality - Enviro Mini 2 Operator's Manual

Operating Instructions
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 silica ash build-up).
Overfiring should not occur if stove is operating properly, if stove looks like it is buring unusually high
turn off the unit with the power button, DO NOT unplug. There is a built in safety switch if unit gets too
hot from overfiring it will shut down automatically.

Due to fuel quality the slider damper and control board trims may need to be fine-tuned.
1. 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).
2. 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.
3. 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).
4. 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.
