hold the Feed Rate Trim button down and press the Heat Level up or

down buttons to adjust the setting.

5. COMBUSTION BLOWER TRIM BUTTON: Used to change the

Combustion Blower trims in 5 volt increments for all feed settings until

it reaches line voltage. When this button is pressed, all the light will

AUTOMATIC SAFETY FEATURES

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.

The most common cause for this is an empty hopper. This switch should only be by-passed for testing purposes by a technician.

The stove and insert have 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 as the exhaust temperatures drop below 120°F (49°C), the unit will shut down.

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.
