500,000 BTU/h High-Output Heating Performance

The L.B. White FOREMAN® 500 DF 2.0 delivers a rated heating input of 500,000 BTU/h for demanding temporary-heating applications. Its forced-air system provides a rated blower output of 3,457 cubic feet per minute (CFM) and a published heated-air output of 2,350 CFM. The fully welded heat exchanger transfers energy from the combustion process to the circulating air while keeping combustion exhaust separate from the heated supply air. This indirect-fired design is suitable for applications requiring heated air to be distributed into work areas without direct mixing of burner exhaust into the supply stream. Actual heating coverage depends on ambient temperature, enclosure dimensions, insulation, air infiltration, duct configuration, and other site conditions.

Dual-Fuel Indirect-Fired Heating Technology

The L.B. White FOREMAN® 500 DF 2.0 uses a Riello® burner and indirect-fired heating technology to provide high-output supplemental heat. The burner heats the fully welded heat exchanger, while the integrated blower circulates air across the exchanger to deliver heated air into the intended space. Combustion gases are routed through a separate exhaust system rather than being mixed directly with the heated supply air. The dual-fuel configuration operates on liquid propane or natural gas, allowing flexibility where either approved fuel supply is available. Manufacturer-published maximum fuel consumption is approximately 23.0 lb/h for LP and 500 cubic feet per hour for natural gas. The specified minimum and maximum inlet gas pressures are 8 and 13.5 inches water column for both fuel types. Correct fuel selection, supply capacity, inlet pressure, combustion-air provisions, and exhaust installation are essential for safe operation. Follow the current L.B. White owner's manual and applicable fuel-gas codes.
