Gas heating - health and safety issues - Better Health Channel

Consider replacing open-flued gas heaters with room-sealed gas heaters or split systems at the next opportunity. Old unflued gas heaters Unflued gas heaters draw air from within the room and emit combustion products back into the same space where the heater is located which can lead to serious health problems including death.

Exhaust gas and air pollution control - Dürr

In process terms exhaust gas is the generic name for gas contaminated with pollutants from a process. This gas might or might not contain oxygen. We use the term exhaust air if the gas in question is ambient air with a normal oxygen content and low pollutant concentrations. Many chemical and combustion processes generate exhaust gas containing little or no oxygen (inert exhaust gas) for example.
