Figure 41: Efficient Flame.
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.
• 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.
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).
Taking a reading of vacuum pressure inside the firebox
with a magnehelic gauge can be used to set the slider
for best combustion. The slider damper should be set
only on a hot stove (operating for thirty (30) minutes
or more) by placing a Magnahelic Pressure Gauge in the
firebox. The reading can be taken from the ⅛” (3 mm)
hole located in the front of the firebox under the door
(see Figure 42). The best settings are a reading of
approximately 0.10 inches of water column on the
high fire setting. Some fuels may require higher or
lower settings.
