Figure 33: Efficient Flame.
SLiDeR/DamPeR Set-uP:
THE SLIDER / DAMPER MUST BE SET AT TIME OF INSTALLATION. A Qualified Service Technician 
or Installer must set the Slider Damper. This is used to regulate the airflow through the pellet stove. The 
slider damper knob is located on the left cab side (see Figure 7). 
If the fire should happen to go out and the heat output indicator has 
been set on the lowest setting, the Slider Damper should be pushed in 
slightly, decreasing the air in the firebox.
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.
Figure 32: Slider / Damper Knob.
• 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 8.
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 when the heat output level 
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).
guiDeLineS foR fine-tuning foR fueL QuaLity:
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.
