FAQs
1. Can I use this heater indoors?
This is a direct-fired heater and must be used in well-ventilated or outdoor spaces only. It is not suitable for sealed indoor use without proper ventilation.
2. Does the THC-175DF require electricity?
Yes, it requires a 115V power source and draws 15 AMPs. The ignition system and fan both require electricity to operate properly.

The unit is dual-fuel and includes a conversion kit that allows you to switch between propane and natural gas easily, typically within just a few minutes.
