Installation
SLIDER/DAMPER SET-UP:
This is used to regulate the airflow through the pellet
stove. The slider damper should be initially set by a
trained technician using magnehelic.
The slider damper knob is located on the left side of the stove.
The combustion exhaust blower is a variable speed blower
controlled by the heat output button. This blower will decrease
the vacuum pressure inside the stove and as the heat output
button is turned down. The vacuum pressure inside the firebox
will increase as the combustion exhaust blower increases in
speed (higher heat output setting).
If, after long periods of burning, the fire builds up and overflows
the burn pot or there is a build up of clinkers, this would be a
sign that the pellet quality is poor, this requires more primary air,
the slider damper must be pulled out to compensate. Pulling the
slider damper out gives the fire more air.
Figure 30: Efficient Flame.
IMPORTANT: Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge should
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 using a Magnahelic Pressure Gauge to measuring the
pressure in the firebox. The best settings are a reading of approximately 0.11 0.12 inches of
water column (27.4 - 29.9 Pa) on the high fire setting. Some fuels may require higher or
lower settings. The reading can be taken from the ” (3 mm) hole located on the front of the unit
below the ash shelf.
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 (see Figure 30).
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).
