1. Conditions that warrant more combustion air are:
Hardwood pellets
Higher altitudes
Increased heat settings (3- 5)
2. Conditions that warrant less air:
Softwood pellets
Low altitudes
Lower heat settings (2-3)
3. Conditions that warrant even less air:
Softwood pellets
Low altitudes
Lower heat settings (1-2)
Things to watch for:
TOO LITTLE AIR
• Extremely lazy flame
• Extremely black and dirty conditions in firebox
• When extended burn on High Settings, too many pellets in firepot
TOO MUCH AIR
• Flame is aggressive but as time progresses, the flame is barely visible
• Fire disappears in burn pot, shown below, or goes out on low settings
•
Note: Once you have determined the correct air usage for the heat setting and local site
conditions, the air damper control will not need to be adjusted as often. Remember, any
change in site specific conditions will require an adjustment of the air damper.
