One of the tiles incorporated an adaptor so that it could be connected directly to the flue
pipe which ran from the ground floor to the loft space.
The risks associated with blocking a live flue
could result in carbon monoxide entering properties and potentially killing all occupants.
are listed Category IV double-wall special gas vents intended for use with high-efficiency condensing boilers, factory-built by a reputable manufacturer.
PRINCIPLE OF THE FLUE
GAS DRIVEN OPEN ABSORPTION SYSTEM
Had they been tempted to fit a gas log fire or stove without using a Gas Safe or HEVAS accredited firm, they could have leaked deadly carbon monoxide across the flues
If they are not working properly or if the flue
is blocked, this can cause a potentially lethal situation.
The coroner said: "It seems to me a very important lesson can be learned from this death that may be of assistance to other people who have chimneys and flues
In metal flues
, a simple B class pipe works for gas, but a Class A pipe is needed to exhaust wood smoke and it is rated for temperatures up to 2,600[degrees]F if I recall correctly (used to be 2,200[degrees]F).
The integrity of warm air flues
, which vent through roof ridge terminals, was discovered to have been disrupted in 11 of the properties, potentially causing a build-up of lethal carbon monoxide in the loft space.
The researchers are now working with engineers to scale up the technology and study its effectiveness in flues
Most have cracked and deteriorated, opening gaps around the flues
The trade categorises chimneys and flues
into class 1 and class 2.
To allow air to move through the tenements, Thomson suggested brick construction incorporating ventilating flues
placed parallel to the smoke flues
The same applies to fireplaces, chimney, and flues
Motivated by the shortage and high prices of fossil fuels in the 1970s, Americans turned in droves to wood heat, but all those puffing flues
produced a lot more than energy independence.
