Boiler flue through conservatory roof.
The boiler or its flue as close to the conservatory as you re proposing to put the conservatory to the boiler flue then you or your conservatory builder would be in contravention of section 8.
How far this is will depend on the size of your boiler but is typically between 30 60cm above below or to the side of an opening.
Think of it this way.
If everyone who installed a vertical boiler flue through a roof had to fix leaks right left and centre then no one would install them at all.
Can a boiler flue go through a conservatory roof.
The flue won t get hot since even the inside compartment is only designed to take warm and wet gas and is itself made of plastic so there should be no problem with going through the polycarb roof.
However if a vertical flue is badly fitted then yes you could have a leak on your hands.
However to comply with the approved document j of the building regulations the flue still needs to rise a total height of at least 4 5m unless the appliance manufacturer specifies less.
However the boiler flue manufacturer s instructions are final so if there s nothing specific in the vertical flue kit installation manual then call the manufacturer for advice.
No boiler builder will allow to put a elbow out and then a vertical channel through the roof of the conservatory as the terminal would be too close to the wall of the house.
