FINE TUNING THE BURNING OF PELLET FUEL
Combustion Air Shutter:
The combustion air to the burn pot is controlled by the round knob on the right side of the
pellet stove, below the control panel. It is connected to an air shutter inside the stove. To
increase combustion air, push the knob in. To reduce combustion air, pull the knob out.
If the fuel pellets are consumed too fast, giving very brisk bright flames with flame height
fluctuating significantly, the combustion air to the burn pot can be reduced by pulling the
control knob and rod out. Care should be used to not to reduce the burn pot combustion air
too much as to cause a poor, lazy burn that will soot up the door glass.
The air shutter can also be used to slow down the burn rate of pellet fuel on low to prevent
flames in the burn pot from going out. Remember that there is the LOW ADJUST button on
the control panel to make adjustments to the fuel feed on lowest heat level. See LOW
ADJUST button description.
In most cases, the stove operate best with the air shutter wide open, with the rod pushed all
the way in.
Make sure the burn pot is properly seated:
If the burn pot is not properly seated into its holder, combustion air will flow around the burn
pot instead of into the burn pot. This will cause poor combustion, which eventually overfills the
burn pot with unburned pellets and extinguish the flames.
Improper seating of the burn pot will also cause fuel pellets to not fall into the burn pot and/or
bounce outside of the burn pot.
Keep the Burn Pot Clean:
When burning low quality pellet fuel or after long periods of burning, excess ash accumulates
in the burn pot and obstructs the combustion air holes. This is evident by lazy orange flames
that soot up the door glass frequently. Scrape out the ash build up in the burn pot and poke out
any obstructions to the air hole. Keeping the burn pot clean will allow the pellet stove to
operate at its maximum efficiency and lower the overall frequency of maintenance.
