Installation
The low burn collar must be set on a hot stove; run the unit on low for 30 minutes, and place a Magnahelic
Pressure Gauge in the firebox (test port is located in the center of the stove just below the door opening).
Set the slider at 0.11” W.C. (30 Pa) for the rebox vacuum and lock the set collar in place (refer to Figure
23). Some fuels may require higher or lower settings.
Figure 25: 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). If this happens, pull the Slider Damper out slightly to increase the
air flow to the fire.
The combustion exhaust blower is a
variable speed blower controlled by
the heat output setting. This blower
will increase or decrease speed as
the heat output button is turned up
or down.
• If the fire should happen to go out
and the heat output indicator has
been set on the lowest setting, the
Slider Damper may need to be pushed
in slightly, decreasing the air in the
firebox. Or the Low Feed Trim can be
adjusted.
• If, after long periods of burning, the
fire builds up and overflows the burn
pot or there is a build up of clinkers,
this could be a sign that the pellet
quality is poor, or the Air to Fuel ratio
is wrong. This requires more primary
air, the slider damper must be pulled
out to compensate. Pulling the slider
damper out gives the fire more air.
