TROUBLE SHOOTING - continued
The 200
o
F High-limit switch has tripped.
• Reset the switch and determine the cause. It is normally a faulty circulation fan. If the circulation fan does not operate,
apply 120 volts directly to the circulation fan. If it still does not operate, replace the circulation fan.
Heater will not shut off.
• If room thermostat is used, make sure it is turned down below the room temperature
• Disconnect one of the wires to the exhaust temperature sensor; the heater should then shut off. Replace sensor
• Depress the ON/OFF button to “OFF”. If the heater will still not shut off, disconnect power to the unit and call your local
dealer for service.
Heater Flame keeps going out on “LOW” setting.
If the fl ame goes out and leaves fresh unburned pellets in the burn pot liner, then the fi re is going out before the unit shuts off.
• On the control panel, use HEAT button to turn the heat level up to the next setting. Poorer quality pellets require a
slightly higher setting.
• If it is on heat level 1, you may also adjust the fuel feeding rate slightly by pressing the Auger Trim button
.
Door Glass has soot buildup at a fast rate and fl ame is lazy with black tips.
• The vent pipe (including air intake) may be dirty or partially blocked restricting air fl ow to the unit.
• The intake butter fl y valve might be set at too low position.(see page 15 )
• Burn pot holes are blocked. Let the unit cool and clean burn pot and burn pot liner (be sure to follow instructions for
disposal of ashes found on page 29)
• Circuit board malfunction. Time the fuel feed light at each setting (after the stove has completed the initial “Start Up”
sequence. Check the timing against the timing chart (found below), if the auger motor runs constantly there is a problem
with the circuit board
• Combustion/Exhaust blower is not operating. Check the combustion/exhaust blower is operating. If not, bypass the
exhaust temperature switch. If the motor operates, replace the exhaust temperature switch. If the combustion/exhaust
blower still does not work, apply 120 volts directly to the exhaust blower motor. If the motor still does not work, replace
the exhaust blower motor.
• Poor fuel quality. The type of pellets being used may be of poor quality. If possible, try a different brand of pellets (refer
to fuel type information on page 3).
