Movement of airthrough a house with a flueless fireMovement of airthrough a house with a chimney Air movement A chimney or flued fire Catalytic converters , by comparison,draws a huge amount of air from around your house. This is warm air (that you have paid to heat) which is replaced by cold air leaking in through windows and doors. Flueless fires All Burley flueless gas fires incorporate acatalytic converter. This is a honeycomb which is coated withrare metals. Oxygen ‘sticks’ to the coating. If a carbon monoxide molecule meets it, the oxygen converts the carbon monoxideto carbon dioxide (which is harmless and ispresent in fresh air). gently convect heatthroughout the entire house. A small air vent regulates air into the room which is being heated. This heated air dissipates away from the fire and circulates around the house. Burley has NEVERhad a catalytic converter fail or need replacing.All Burley appliances are CE marked byinternational test houses. One of the tests that the fires must pass is to have the catalytic converter removed. In this condition it must still pass all the strict combustion tests.
