360,000 BTU/h High-Output Heating Performance

The L.B. White Journeyman® 360 Oil provides a maximum heating input of 360,000 BTU/h (105.5 kW), making it suitable for demanding temporary-heating applications. Its 2,000 CFM forced-air system distributes heated air through the discharge outlets to help warm construction and industrial work areas. The indirect-fired design transfers heat through a heat exchanger while routing combustion gases through a separate exhaust system. This arrangement helps prevent direct mixing of combustion exhaust with the heated supply air. Actual heating coverage depends on enclosure size, insulation, ambient temperature, air infiltration, duct arrangement, and other site conditions.

Indirect-Fired Diesel Heating Technology

The L.B. White Journeyman® 360 Oil uses an oil-fired combustion system designed for #1 or #2 diesel fuel. The burner heats the internal heat exchanger, while the integrated blower circulates air across the exchanger to deliver heated air into the intended space. Combustion products are discharged through a separate flue rather than being mixed directly with the heated supply air. This configuration is useful for approved temporary heating applications where separation of combustion exhaust from the heated air is required. The published pump pressure is 170 PSI, and the specified burner nozzle is 1.75 x 60B. Follow the manufacturer's instructions for fuel selection, combustion-air requirements, exhaust installation, and safe operation.

2,000 CFM Airflow & Ducted Heat Distribution

The L.B. White Journeyman® 360 Oil provides a rated airflow of 2,000 cubic feet per minute (CFM) for distribution of heated air. Its ductable configuration supports delivery of heat to designated work areas through compatible ducting. L.B. White specifies that the heater can accommodate duct lengths of up to 100 feet per discharge opening, provided the installation does not exceed the maximum static pressure of 0.5 inches water column per opening. When only one outlet is ducted, the other outlet must remain open. Blocking an outlet to extend duct length beyond the manufacturer's limit is not permitted because excessive static pressure can trip the high-limit switches. Use approved ducting and maintain unobstructed airflow in accordance with the current owner's manual.
