mode. Burning corn in thermostat mode is difficult due to
the nature of the ash or “clinker.” This solid mass of ash
will not be blown out of the firepot during reignition and
may not get hot enough to light.
It is recommended when operating the stove in the thermostat
mode, to use the lowest range to keep up with the room
temperature loss. This keeps the stove from going in and out of
standby and ignition, preventing fuel pileups and loss of fire.
At anytime during normal operation you may press the
OFF button to safely shut down the stove.
IMPORTANT:
NEVER UNPLUG YOUR STOVE WHILE THERE IS FUEL
BURNING IN THE STOVE. The stove is designed to exhaust
smoke through the vacuum created by the combustion fan.
Doing so will cause combustion fan to stop and smoke will
enter the room through air intake holes.
