Frequently Asked Questions
Is this heater safe for enclosed or semi-enclosed job sites?
No. The F-1500T is a direct-fired heater designed for well-ventilated areas. It emits combustion gases into the heated space, so always ensure proper airflow and follow all safety guidelines. It is CSA-certified and equipped with a 100% flame safeguard system for safe operation when used correctly.
How much fuel does it consume per hour?
At full output (1.5 million BTU/hr), this heater consumes:
- 69 lbs/hr of propane
- 1,428 cubic feet/hr of natural gas
Plan your fuel supply accordingly, especially for continuous or remote operations.
How do I know if a 1,500,000 BTU heater is enough for my space?
Heating requirements depend on space size, insulation, airflow, and heat loss. A 1,500,000 BTU/hr heater suits very large or poorly insulated areas. Use our BTU Calculator to estimate your heating load and determine if one or multiple units are needed.
What power supply is required?
The Flagro F-1500T requires a 115V / 20-AMP power source for the fan motor and ignition. This standard voltage is available on most commercial job sites. Always ensure your generator or power supply can handle the load for safe operation.
Where can the Flagro F-1500T be safely operated?
The F-1500T is designed for open-air or partially enclosed commercial spaces with proper ventilation. Ideal for temporary heating during construction, renovation, or emergency response. It is not intended for fully enclosed indoor use, as it releases combustion gases into the heated space. Ensure adequate airflow for safe operation.
