Gas Boiler Flue Location

bonnieprince

Hi All

Can anyone tell me or point me in the way of the regs for the location of a flue, it is being fitted in a new extension near my boundary wall.

thanks

Generally must be compliant with Part J Building Regs, BS.

Just to let you know all gas boilers usually refere to the same documents Therefore check out the following links.



FYI. A gas boiler is designated as a Balanced Flue Fan Draught.
measurements were originally designed for non-condensing boilers. The boiler being fitted will probably be a High Efficiency condensing boiler. The flue discharge which it emits is lower in temperature and will look like "steam" or "condensation". This is refered as "plume". This can cause a nuisance to neighbours and the distance between windows and boundary's has to be increased accordingly. (some references now ask for 2.1 to 2.5m)

Part J regs Regs- 600mm from boundary, (or facing wall, fence etc if nearer). Also min 2m from an opening door or window on facing property. Cage if 2m or less above ground level.
ODPM (UK regs) guide (which is for the condensing exemption procedure only)- 2.5m from boundary and 2.1m from ground if a patio, walkway, car parking etc.
Manufacturer's Instructions have to be complied with over all of this.
The end result being that you could go as close as 600mm facing from boundary (300mm in line) but the key is 'nuisance'.
If the householder is taken to court for the 'plume' being a nuisance and proved he can be made to move it.

Edit: this is for oil boilers, perhaps guidance for gas boiler flue might be quite different (maybe less restrictive?)

The requirements for flue terminals are always a lot shorter or less than people think.
If your neighbours flue gases bother you ,maybe ask them to fit a plume management kit. This means the plume can be directed away from your house.

Link to one paticular flue positioning.

Thanks for the replies.
I was just concerned about where my flue would exit my new extension and without interfering with my neighbours. I reckon the exit will be about 26 inches from boundary wall so that should be ok (660mm).
Thanks again.

Surly your fitter would take this into account when surveying the job!!

If your boiler is a condensing boiler with the terminal facing onto the neighbours property the "plume" could cause a problem as the earlier posts have said.

my plumber will survey but extension need to built and i just wanted to know what i have to watch out for.

Hello all, a bit of advice needed, I moved into a property some years ago and immediately noticed the neighbours gas flue is over the boundary line of my property and protruding at least 6 inches into my property from his kitchen extension. (Not spotted by surveyor). It also measures 200-300mm from my downstairs toilet vent and 400-500 mm from the same toilet window.

This is a nuisance in winter as i cannot open the window for ventilation. I approached the neighbour and discussed this in a friendly matter and his reply was he had no money to alter the boiler. That was 2 years ago. I approached our local county council and they had no idea or advice of what to do and said i need to see a Solicitor.

Has anyone had a similar experience or shine some light on how i can approach this matter.

If you could post a picture that would be a great help.

There are regulations as to the location of flues but without seeing it and precise measurements taken it's hard to say.

If it's a condensing boiler manufacturers instructions have to be followed and one of them is "it must be installed in such a way that it does not cause a nuisance.

You could try the RGII route but 2/3 years down the line you could be looking at a solicitor.

A 'plume management kit' is available. This will allow the plume to be brought to a greater height and so reduce the nuisance. It should not be a 'big job' to fit one.

This is the sort of thing: http://www.mrcentralheating.co.uk/Retro-fit-Plume-Management-Kit-60mm (though I would get local advice so you get the right one to fit. And you must get a registered gas installer to fit and certify it.

As you can see this stuff is not exactly megabucks compared to solicitor's bills so it might be worth offering to contribute to the cost to just solve the problem for once and for all.
