1,000,000 BTU Dual-Fuel Heating
One of the primary advantages of the Flagro F-1000T is its ability to operate on either propane or natural gas.
This provides flexibility for contractors working at locations with different fuel availability.
Propane Operation
The F-1000T delivers 1,000,000 BTU/hr of heating input when properly configured for propane.
Published propane specifications:
- Heating Capacity: 1,000,000 BTU/hr
- Fuel Consumption: Approximately 46 lbs/hr
- Minimum Inlet Pressure: 11″ W.C.
- Maximum Inlet Pressure: 14″ W.C.
A properly sized propane supply and approved fuel connection equipment are required.
Natural Gas Operation
The heater can also operate on natural gas.
Published natural gas specifications:
- Heating Capacity: 1,000,000 BTU/hr
- Fuel Consumption: Approximately 952 cubic feet per hour
- Minimum Inlet Pressure: 7″ W.C.
- Maximum Inlet Pressure: 14″ W.C.
The gas supply must provide adequate pressure and volume for the heater’s full heating load.
Fuel Selector Valve
The F-1000T includes a fuel selector valve for switching between propane and natural gas.
The valve must be positioned correctly for the selected fuel before operation.
Fuel changes and gas connections must follow Flagro’s approved procedures and applicable fuel-gas regulations.
Direct-Fired Forced-Air Heating
The Flagro F-1000T uses a direct-fired heating system.
Unlike an indirect-fired heater with a separate heat exchanger, the F-1000T introduces burner combustion products into the heated airflow.
Its 1 HP blower delivers approximately 7,000 CFM of heated air through the large 26-inch discharge opening.
This provides substantial heating capacity for suitable construction environments.
Benefits of Direct-Fired Heating
- High heating output
- Powerful forced-air circulation
- No separate indirect-fired heat exchanger
- Propane and natural gas compatibility
- Thermostatic burner operation
- Portable equipment configuration
Important: Because combustion gases enter the heated air, the F-1000T requires adequate fresh-air ventilation. It must not be used in sealed or inadequately ventilated spaces.
Common Applications for the Flagro F-1000T
Commercial Construction Sites
The F-1000T is designed for large temporary heating applications during construction, renovations, and building maintenance.
Typical applications include:
- Large commercial construction projects
- Winter construction operations
- Temporary construction work areas
- Building renovations and alterations
- Industrial construction projects
- Temporary heating during permanent HVAC installation
Industrial Maintenance and Repair
Industrial maintenance projects may require temporary heat during colder weather or facility shutdowns.
The F-1000T provides high-output heating for appropriate, adequately ventilated maintenance and construction environments.
Large Temporary Work Areas
The F-1000T can support temporary heating in suitably ventilated construction enclosures and other approved work areas.
Heater selection must account for the building’s heat loss, available combustion air, occupancy, and applicable safety requirements.
Emergency Construction Heating
The heater can also support temporary heating during building repairs, alterations, and approved emergency construction situations.
