Frequently Asked Questions
Can I use this heater indoors?
The F-375 is a direct-fired propane heater and must be used only in well-ventilated or outdoor spaces. It is not safe for sealed indoor use without ventilation.
Does it need electricity to operate?
No. The F-375 runs without electricity, using manual ignition and propane fuel. This makes it ideal for remote job sites, trailers, or backup heat needs.
What’s included with the heater, and is the fan assembly required?
The F-375 comes with a 20 ft propane hose and a 20 PSI adjustable regulator. The fan assembly (800 CFM) is optional and recommended if you need better air distribution across a larger area. Without the fan, the unit still operates effectively via radiant and convection heat.
