Four Modes Of Operation

The Dual Fuel Ready Furnace with burner installed gives the consumer the choice of four different modes of operation.
- Wood:
The most economical choice. The wood mode allows the user to operate the furnace burning only wood. Heating with wood is endorsed by the U.S. Forestry Service and the Union of Concerned Scientists.
- Clean StartT:
This wood burning mode allows the Dual Fuel Burner to operate for a selected period of time in the beginning of each burn cycle to create immediate high temperature in the secondary combustion area of the Ripple Top® and Heat Lock Baffle® firebox design. This mode also provides automatic backup with alternate fuel.
- Dual Fuel Backup:
This mode automatically initiates the Dual Fuel Burner as a backup if the operator does not refuel the furnace with wood.
- Fuel Oil - LP/NG:
This mode allows operation of the furnace when not firing with wood. The Liquid Propane, Natural Gas, and Fuel Oil burners are shipped with a 150,000 BTU rating and may be increased for certain applications.
* Fuel oil must be at proper viscosity to operate correctly.
The Dual Fuel System control knob is located on the side panel pump cover. Pertinent information for the Dual Fuel System is mounted inside the side panel.
