Termination into boundary .

[stani]

I've just been to look at a new property for our clients, our existing boiler an old Worcester combi, terminates right onto the boundary between next door, when the appliance was installed next doors wall were 3 metres away, however they have had an extension built, which now drops the boundary space to exactly 1 metre.
my cause for concern is the fact they have put a new back door directly opposite our terminal, it is now 1 metre from the terminal, surely building control should have highlighted this to the neighbours prior to building, I am trying to find any legislation to help. TB 016 seems to be they only document unless any body can help!

the building work is still ongoing.

Not the neighbours problem. The boiler should have been installed as though there was a structure on the boundary line. Your boiler has been wrong from day one.

 

[stani]

That's actually how I read it, just not sure what options I have, boiler is a non condense, and I think 15ish years old, was legislation applicable then?

Boundary rules haven't changed much for as long as I can mind, apart from the new rules on plumes. I think it was 1.5m pointing toward a boundary, I can't quite remember.

It sounds like that back door opens into your garden lol!

Yeah old boiler is wrong you can't say sorry sir you can't build a extension on your own property as my boiler flue is there first

If the boilers 15yo then they"ve had there moneys worth.I would talk them into a new bolier with plume kit.

 

[stani]

It's more the problem the back door is directly opposite, surely architect/building inspector should have picked this up.

Even with a plume kit, is it not still breaking the regs terminating within a metre from a boundary ??

You check MI's?
Of top of head some boilers can be 600mm to boundary wall as per MI's. If neighbour wants put door opposite then they are in wrong in my opinion.

 

[Ermintrude]

Yes it was

 

[dmheat]

Must modern boilers MIs stipulate 600mm from a facing surface or boundary, or 300mm horizontally from boundary line. If your terminal is within your property, and there is a minimum of 600mm to the facing boundary line, then it's a spanner in the works. If you wall, and thus terminal in ON the boundary line, then yeah never fitted correctly.

 

[stani]

The wall is directly on boundary line.
It's not really a massive concern for us, previous installer, occupier, yes.
my concern is the open doorway directly opposite our terminal, surely somebody should have picked this up from the neighbours point I.e. Architect/building inspector

 

[diamondgas]

Worcester 24/28CDi, for example, states 600mm from a surface facing a terminal.... I'd check the original installation requirements personally. If it was installed on or across the boundary line and not 600mm away then the old appliance was not installed correctly and a new appliance flue cannot be fitted in the same place. IMO

 

[Reg Man]

Not necessarily, the BCO is not a gas engineer. My guess is the flue terminal position will have to be moved as it has never complied. If it kicks off some one may force the boiler to be turned off.

 

[GrahamM]

Right as per BS5440-1:
the flue termination if facing property boundary line must be 600mm away.
300mm from side of flue parallel to boundary line.
It is not permitted to have a building opening withing 2m of a flue termination facing directly opposite. So if your flue termination is for example 600mm from the property boundary they cannot put a door/window directly opposite unless it is 1.4m away from the boundary line.
