Your pellet Stove has the following safety features:
A. The stove will shut off when the fire goes out and the exhaust temperature drops below 120°F
(49°C).
B. The stove has a high temperature safety switch. If the temperature on the hopper reaches 200°F
(93°C), the auger will automatically stop and the stove will shut down when the exhaust temperature
cools. If this happens, call your local dealer to reset the 200°F (93°C) high limit switch. ALSO FIND
THE REASONS WHY THE UNIT OVERHEATED.
C. The unit has a convection fan control over-ride. This function causes the convection fan to reach its full
speed when the temperature at the back of the firebox reaches 160°F (71°C). This is a normal safety
feature of your unit. To compensate for the fan cycling action that may occur, turn up the blower
control proportionately to the heat output.
D. If the power goes out, the unit will stop running. When the power comes back on, the stove will not
restart unless the exhaust temperature is still above 120°F (49 °C).

positions.
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 the fire should happen to go out and the Dial-A-Fire has been set on the
lowest setting, the Slider Damper should be pushed in slightly, decreasing the
air in the firebox or the Dial-A-Fire can be turned up slightly.
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.
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.
Taking a reading of vacuum pressure inside the firebox with a magnehelic gauge
can be used to set the slider for best combustion. The best settings are a
reading of 0.12 to 0.13 inches of water column (30 Pa) on the high fire
setting. Some fuels may require higher or lower settings. The reading
can be taken from the 1⁄8” (3 mm) hole located on the front of the unit below
the door and behind the magnetic ash lip.
