COMBUSTION AIR ADJUSTMENT
Combustion air can be adjusted by rotating the air shutter to close / open the air duct. Air adjustment is critical
for proper combustion and stove efficiency.
Adjust the shutter so the flame is bright yellow in appearance and is actively moving (not lazy). Dark flames,
smoke or black tips on the flame is an indication of too little air.
If the flue configuration is tall, over 15 feet, the shutter should be closed more than a shorter vent since the
higher flue will naturally draft the stove and increase the intake air velocity and volume. This can cause the
pellets to be blown out of the firepot and the efficiency of the stove will decrease due to the heat going up the
flue instead of through the heat exchanger.
