Dual Fuel Ready Models

Central Boiler, known for their innovations in wood heating technology, has developed a Dual Fuel Ready model which allows the furnace to be fitted with an optional Fuel Oil, Natural Gas, or Propane burner. The Dual Fuel System has four modes of operation: Wood Only, Clean Start, Dual Fuel Backup, and Fuel Oil/LP/NG. Laboratory test have shown efficiencies over 85% with these fuels. This flexible Dual Fuel system allows you to adapt the furnace to your individual heating needs. The Dual Fuel Ready option allows for easy installation of the oil or gas burner (not included in furnace price).

Four Modes Of Operation

The Dual Fuel Ready models with an optional fuel 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. Wood is a totally renewable resource.

  • Clean Start™: 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.
