A. The stove and insert have a low limit safety switch located on the housing of the exhaust blower. If the exhaust temperatures
drop below 120°F (49°C) the unit will shut down and will be required to go through a full start up procedure again. You
will see a flashing #3 Error code. The most common cause for this is an empty hopper. This switch should only be by-
passed for testing purposes by a technician.
B. The stove has a high limit safety switch located just below the hopper behind the external body panels. If the temperature
of this switch reaches 200°F (93°C) the auger will stop feeding fuel and the unit will shut down.There will be a flashing
#4 error code. The 200°F (93°C) switch is a manual reset and should only be reset by a service person who can first
diagnose the reason for failure. The two most likely causes are Convection Fan failure or High Limit Switch failure. Either
one needs to be properly diagnosed and rectified. Since this is a safety switch it should never be by-passed for any reason
other than the service technician to test the operation.
