Shutdown Mode
This mode stops the auger fuel feed system and runs the combustion & convection blowers for 10 minutes or
until the stove exhaust cools below 120° F, at which point all electrical components will be off. Shutdown mode
occurs when "OFF" is pressed on the touchpad or from other causes. If this happens unintentionally, find and
correct the cause and press start on the touchpad. (See Section #9 "Troubleshooting")
Hopper Lid Switch
This device is mounted on the right side of the hopper opening. When the hopper door is open, the switch stops
the auger feed system. If the hopper door is left open for more than one minute, the unit will enter shut‐down
mode. If this happens unintentionally, simply close the door and press start on the touchpad.
Vacuum Switch
The vacuum switch ensures that the vacuum of the entire combustion system is maintained. The switch is lo‐
cated on the inner rear wall of the unit and takes measurement from the fresh air intake tube. If the vacuum
switch fails to read adequate negative pressure for more than one minute, the unit will enter shut down mode.
This feature ensures that the stove will not operate with the door ajar or the ash pan tightened incompletely. If
this happens, find and correct the cause and press start on the touchpad. (See Section #9 "Troubleshooting")
Intelligent Temperature Controller (ITC)
The ITC feature of your stove monitors the exhaust temperature and adjusts fuel feed accordingly to maintain
consistent heat output temperatures. In this manner, the ITC is able to regulate stove heat settings with great
accuracy, compensating for variations in fuel such as size and BTU content as well as optimizing fuel efficiency
and preventing over‐firing.
L250 High Limit Switch
Your pellet appliance has a high tem‐
perature limit switch as an added safety
measure if the ITC were to fail. If the
temperature at this location exceeds
250° F, the unit will enter shut down
mode. If this occurs, find and correct
the cause and press start on the touch‐
pad. (See Section #9 "Troubleshooting")
Power Loss Memory
If the power lost during operation, the
stove will stop running and the fire will
extinguish. When the power is re‐
stored, the stove will restart and return
to the heat and fan setting it was oper‐
ating at before power was lost.
