Flagro F-150 Direct Fired Construction Heater 150000 Btu/h

Product Description

The FLAGRO F-150 is a direct fired construction heater rated at 50,000 to 150,000 BTU/h on vapor propane. It operates without a fan or external electricity, making it a self-contained temporary heat source for job sites where power is limited or unavailable. Output is manually adjustable through a regulator, with manifold pressure ranging from 2-1/4 to 20 psi. The unit weighs 32 pounds and ships with a 20-foot hose and an adjustable regulator rated to 20 psi maximum. Licensed contractors and construction crews use this heater to maintain safe working temperatures during cold-weather framing, concrete curing, and interior finishing work.

The F-150 is designed for temporary heating applications on residential and commercial construction sites, as well as maintenance and renovation projects. Its propane-only, fan-free design allows placement in areas without electrical access. The adjustable output range lets operators match heat output to the size of the enclosed space being warmed. Fuel consumption runs from 2.3 to 6.9 pounds per hour depending on the output setting selected.

Installation Notes

This heater should be set up and serviced by qualified personnel familiar with propane appliances and applicable codes, including NFPA 58 for LP-gas storage and handling. Always shut off the propane supply at the cylinder valve before connecting or disconnecting the hose and regulator. Ensure adequate ventilation in the work area when operating any direct fired heater, as combustion consumes oxygen and produces combustion byproducts. Inspect the hose and regulator for damage or leaks before each use and never exceed the 20 psi maximum regulator rating.
