This heater has built-in safety features to keep you and your family safe whenever using this heater. Firstly, this heater incorporates a flame failure device which ensures that if the flame of the heater goes out, the gas supply is cut, both saving you gas, and preventing accidents or accidental ignition. Secondly, this heater has been designed with an anti-tilt switch, so that in the unlikely event that this heater is tipped or falls over, the gas supply is turned off, extinguishing the flame, greatly reducing the risk of accidental fires.
