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.\u003c\/p\u003e\u003cp\u003eThe 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.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e750,000 BTU\/h heat output with 7,000 CFM heated airflow capacity\u003c\/li\u003e\n\u003cli\u003eDual fuel operation: switches between natural gas and propane without major reconfiguration\u003c\/li\u003e\n\u003cli\u003e16-gauge 304 stainless steel heat exchanger for durability in continuous-duty construction environments\u003c\/li\u003e\n\u003cli\u003eIndirect fired combustion keeps exhaust gases out of the conditioned air stream\u003c\/li\u003e\n\u003cli\u003eDual 16-inch diameter air inlet and outlet ports with ductwork compatibility\u003c\/li\u003e\n\u003cli\u003ecETLus listed and certified to ANSI Z83.7\/CSA 2.14 2011 for Canada and U.S.A. installations\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eCompatible outlet ducting: FV-HDG16 (16 inches x 25 feet).

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.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Capacity\u003c\/strong\u003e: 750,000 BTU\/h\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeated Airflow\u003c\/strong\u003e: 7,000 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTemperature Rise\u003c\/strong\u003e: 130 degrees F at 7,000 CFM\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Type\u003c\/strong\u003e: Natural Gas or Propane (Dual Fuel)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Consumption (Propane)\u003c\/strong\u003e: 37 lbs\/hr\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Consumption (Natural Gas)\u003c\/strong\u003e: 806 CFH\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFuel Tank\u003c\/strong\u003e: External supply\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePower Requirements\u003c\/strong\u003e: 1 Phase 208-230 volts, 18 amps\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Manifold Pressure (Propane)\u003c\/strong\u003e: 1.5 inches WC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eGas Manifold Pressure (Natural Gas)\u003c\/strong\u003e: 2.2 inches WC\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Outlet\u003c\/strong\u003e: 2 x 16 inches diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAir Inlet\u003c\/strong\u003e: 2 x 16 inches diameter\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHeat Exchanger Material\u003c\/strong\u003e: 16-gauge 304 Stainless Steel\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDimensions (L x W x H)\u003c\/strong\u003e: 98 inches x 36 inches x 61 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 1390 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCertifications\u003c\/strong\u003e: cETLus listed, ANSI Z83.7\/CSA 2.14 2011\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eListed For\u003c\/strong\u003e: Indoor and outdoor installations, Canada and U.S.A.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: FLAGRO\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: FVNP-750\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"FLAGRO","offers":[{"title":"Default Title","offer_id":51306772627762,"sku":"FVNP-750","price":21218.83,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/309549407.png?v=1781298102","url":"https:\/\/voomisupply.com\/products\/flagro-fvnp-750-indirect-fired-dual-fuel-heater-750000-btu-h","provider":"Voomi Supply","version":"1.0","type":"link"}
