Natural gas and LPG require a certain amount of oxygen to burn correctly, but inadequate ventilation of gas appliances can create a serious health hazard, know as carbon monoxide poisoning can even be fatal. Every cubicle of natural gas needs 10 cubic metres of air for complete combustion. LPG requires 24 cubic metres of air. Too little air causes incomplete combustion which produces carbon monoxide.

Most indoor gas appliances use the air within the room for the oxygen that they need to burn gas. If the room doesn’t have enough ventilation to allow fresh air into the room, the amount of oxygen available will be depleted and other gases will build up. Indoor gas appliances are designed and tested to operate safely in an indoor environment. They may be power flued, natural draught flued or un-flued appliances. Power flued appliances draw air from within a room and then use a fan or other powered system to push air and combustion products into the same room. Un-flued and natural draught flue systems should not be installed in small rooms (eg bathrooms) or rooms used for sleeping, due to the risk of toxic levels of carbon monoxide building up. When flued systems are installed in other rooms, they must have permanent ventilation outside.
