Flagro FVNP-750 Indirect Fired Dual Fuel Heater 750000 Btu/h

Product Description

The FLAGRO FVNP-750 is a 750,000 BTU/h indirect fired, dual fuel construction heater built for large-scale temporary heating on industrial and commercial job sites. It operates on natural gas or propane and delivers 7,000 CFM of heated airflow through a 16-gauge 304 stainless steel heat exchanger. The indirect fired design keeps combustion gases fully separated from the heated air stream, making it suitable for occupied work areas, enclosed structures, and applications requiring clean air delivery. Power requirements are 208-230 volts, single phase, at 18 amps. Licensed HVAC technicians and industrial heating contractors are the primary installers.

The FVNP-750 is designed for large temporary heating applications including construction sites, industrial facilities, warehouses, aircraft hangars, and event tents. It produces a 130 degrees F temperature rise at 7,000 CFM, supporting effective heat delivery across spaces up to approximately 37,500 square feet depending on ceiling height, insulation, and outdoor conditions. The unit requires an external fuel supply and accepts ductwork on both the inlet and outlet sides. Compatible inlet ducting is the FV-HDV16 (16 inches x 25 feet) and compatible outlet ducting is the FV-HDG16 (16 inches x 25 feet). Dual 16-inch diameter air inlet and outlet ports allow flexible field ducting configurations.

Key Features

• cETLus listed and certified to ANSI Z83.7/CSA 2.14 2011 for Canada and U.S.A. installations

Compatibility

Compatible outlet ducting: FV-HDG16 (16 inches x 25 feet). Compatible inlet ducting: FV-HDV16 (16 inches x 25 feet). Certified for indoor and outdoor installations per ANSI Z83.7/CSA 2.14 2011 Gas Fired Construction Heaters, Unattended Type.

Installation Notes

Installation must conform to local codes or, in their absence, to the National Fuel Gas Code ANSI Z223.1/NFPA 54 and the Natural Gas and Propane Installation Code CSA B149.1. Shut off all fuel supply and disconnect electrical power before servicing the unit. A single-phase 208-230 volt electrical supply with appropriate overcurrent protection must be in place before startup. A licensed HVAC technician or qualified gas fitter should perform all gas connections, ducting, and initial commissioning.
