As well as detecting a blocked supply of oxygen, these must also detect a blocked exhaust or reversed flow in the exhaust flue owing to wind conditions. Two methods are used to provide these, an Oxygen Depletion System (ODS) that measures the availability of oxygen for combustion or an Atmospheric Sensing Device (ASD) measures excess heat rise ...
The flue system is composed of two flues, the inner flue and the outer flue. The outer flue draws air into the bottom of the sealed firebox to allow for combustion. The inner flue draws hot exhaust gasses from the top of the sealed firebox and vents them directly to the outside of the structure through either an adjacent wall or roof.

The air mixed with the rising smoke and increased the combined flow rising up the flue. It produced a circulating air-smoke flow, driving the smoke up into the chimney rather than lingering and often choking the residents. Many fashionable London houses were modified to his instructions and became smoke-free as well as more efficient.
