second setting.

Allow the furnace to run for 24 hours, then evaluate heat delivery to the space, the level of fuel in the
burn pot, and visible emissions before making adjustments to the combustion air and/or Variable BTU
timer. Adjust the Variable BTU timer and combustion air damper so that the space is being adequately
heated while at the lowest Variable BTU Timer setting that keeps the fuel level in the burn pot between
halfway and completely full and the combustion air damper open the least amount that produces no
visible emissions from the vent.

Low Fire

Adjusting the on and off cycle time settings on the low fire timer controls the amount of fuel fed to the
firepot during the low fire mode of operation. The initial setting of this low fire timer is 12 minutes
“OFF” and 2 minutes “ON”.

After approximately 24 hours of operation, the timer “ON” and “OFF” time can be adjusted to reduce
the amount of fuel consumed during this “low fire” mode of operation, while maintaining a fire during
extended period of time during which the furnace is idle.

Initial Settings

The pilot (Low Fire) timer is preset at the factory at 12 minutes “OFF” (green indicator) and 2 minutes
“ON” (red indicator). Further adjustment can be made with user experience.

The variable BTU timer relay controls the auger drive rate. It comes set from the factory at 30 seconds
ON (red indicator) and 30 seconds OFF (green indicator). Allow the furnace to run for 24 hours, then
evaluate if adjustment is necessary.

When using premium wood pellets, start with the combustion air damper approximately 1/3 open.  For
other types of fuel, start with the combustion air damper approximately 1/2 open.  Allow the furnace to
run for 24 hours, then evaluate if adjustment is necessary.

This furnace is equipped with an automatic/manual fan switch. Use of the manual setting while the
furnace is in operation may cause the furnace to shut down automatically due to the low temperature
control. The manual position may be used for summer operation.

Power Failure Considerations

In the case of a short period power outage, the furnace will continue to burn the fuel in the burn pot
and will resume normal operation when power is restored.

If the power outage is for an extended period of time, the fuel in the burn pot will be consumed and
the fire will extinguish. Should that occur, refer to the Burner Lighting (found on page 26) to restart
the furnace.
