Burning logs or coal produces soot and under the wrong conditions can also produce tar and creosote , these stick to the walls of your chimney or flue and restricts the flow.
The restricted chimney will reduce or stop the draw, in severe cases causing the smoke to come back into the room.
As well as creating a large amount of smoke incomplete combustion will create Carbon Monoxide, which is toxic.
This is why you need to have your chimney swept regularly, to remove all deposits.
We recommend a Carbon Monoxide detector is always installed in the room of the fire or stove.
Current recommended frequencies for sweeping are
Wood - quarterly
Smokeless fuels - at least once a year
Bituminous Coal - at least once a year
Oil and gas - once a year
