The Sunglo Permanent Mount Natural Gas Heater in Black is the perfect solution for those looking for a permanent, built-in, natural gas patio heater. The in-ground post minimizes the deck space needed and creates a streamlined appearance. Being directly plumbed to your natural gas source, the amount of time you are able to enjoy the heater is literally limitless. The heater is manually controlled and requires no electric connections. Once the pilot is manually lit, you'll be able to turn the unit on/off with the control knob found at the front of the unit. The durable, heavy duty corrosion resistant construction of the heater makes it resistant to the harsh elements of the weather, for guaranteed years of use and enjoyment. The heater produces up to 50,000 BTUs of warmth in an almost 12' diameter. For added peace of mind, the heater also features a 100% safety shutoff control. If you are considering multiple units in a single area, it is recommended that each heater be at least 12 Ft. apart.
