Flagro F-1500T Forced Air Construction Heater 1500000 Btu/h

Product Description

The FLAGRO F-1500T is a direct-fired, forced air construction heater rated at 1,500,000 BTU/h and built for heavy-duty temporary heating on job sites and large work enclosures. It operates on propane or natural gas with electronic direct spark ignition and a flame safety control system for reliable, monitored combustion. The 1 HP fan motor delivers 7,000 CFM of heated air output. This unit is built for HVAC mechanics, construction crews, and temporary climate contractors working in large commercial, industrial, or infrastructure applications where high-output heat is required.

The F-1500T is intended for temporary heating of large structures including construction sites, hangars, warehouses, tents, and industrial enclosures. Its dual-fuel capability allows field crews to connect to whatever fuel supply is available on site. A hi/low thermostat control allows operators to manage heat output across varying ambient conditions. The stackable, portable design simplifies transport and staging on active job sites. Low-fire output is rated at 650,000 BTU/h, giving operators meaningful turndown range for smaller or partially enclosed spaces.

Compatibility

Designed for use with propane (LP) or natural gas supply systems on temporary construction heating applications. Fuel connections are compatible with vented regulator model B31R1.25. Installation must conform to local codes or, in the absence of local codes, ANSI Z223.1/NFPA 54 for natural gas and ANSI/NFPA 58 along with CSA B149 for propane.

Installation Notes

Installation and commissioning should be performed by a qualified gas fitter or licensed HVAC technician familiar with temporary heating equipment and applicable fuel gas codes. Shut off and disconnect the fuel supply before making or breaking any gas connections. Ensure adequate combustion air and ventilation for the occupied or enclosed space per local authority requirements. When storing the unit indoors, disconnect all fuel supply lines at the source per manufacturer and code requirements.
