Can a Plumber please tell me the truth

[Beckmeister General]

I'm having a combi fitted in my garage. Now the flue pokes into my alleyway between my garage and next doors wall which is 1000mm.
Now the owner of the corgi registered plumbers who'll fit the combi reckons I only need 600mm. The guy who'll actually will fit the combi called in and thought it was tight and said next doors wall may get stained. When I asked the owner again he said he thinks it'll be fine but If it isn't hell fit a plum kit and point the flue down my alleyway .
Does anyone know the legislation?

From a surface facing the terminal it is a minimum of 600mm, but this does not mean to sya that it will not cause a nuisance factor with the pluming.

Thank Dave,

This is what the guy who's going to install it said. But is it still legal to fit it ?

Any windows in the ally, yours or the neighbours.

Is the ally covered

Should also ask if theres any vents in the wall as well

 

[Beckmeister General]

The alley is not covered and the neighbour has a small frosted en-suite window 2 metres above the flue

 

[bengasman]

only one answer possible here. it depends on what the service and installation manual says about this particular boiler.

I feel the installer is putting the onus on me, where it should be him telling me what is what.

As bangas says call the manufacturers and ask them

the RGI is right it IS your problem if your nieghbour complains

 

[fitz1]

personally i think your asking for future grief.in winter the alley will be like the foggy streets of london in jack the rippers day. if it does cause staining or any form of nuisance , you could be forced to pay for it to be resited elsewhere.if the the fella of whom your contract is with is so certain it will be o.k , ask him to guarantee the install against such comebacks.Also , building regs state 2.5m.MI,s only come into effect if no nuisance or damage to neighbour or property is present after install.

Would a plume kit help? It wouldn't take it above my roof level but it would nearly take it to the end of my house.

 

[doitall]

Environmental health also advise 2.5m.

If there's an alternative e.g the garage roof for example then I would go for it

 

[Agile]

Many manufacturers require more than 600 mm, often 1200 mm.

But quite apart from that the draft Building Regulations require that flues are not to discharge towards a boundary within 2500 mm !!!

You really seem to have engaged a team of cowboys who are short of work and plan to install it anyhow.

Thats not your problem as they are the experts!

I would strongly suggest that you do not pay them the full amount until it has been inspected by both CORGI and the local Building Inspector to see if they can agree that its acceptable. If not then its the installers responsibility to sort it out at their expense. CORGI can serve a defects notice on them.

but If it isn't he'll fit a plum kit and point the flue down my alleyway

That would be fine.

Also , building regs state 2.5m.

Not so. The Building Regulation (ADJ - diagram 3.4, page 42) figure is 600mm as already stated. The figure of 2.5 metres is purely used in the condensing boiler exemption assessment, which isn't relevant in this case.

There is a slight risk of water condensing of your neighbour's wall and window. this water will be mildly acidic so might possibly cause discolouration or damage to the wall/window. It might be best to fit a plume diverter kit to direct the condensate plume away from your neighbour's wall.

 

[Agile]

The building regulations fogure of 600 mm is based on non condensing natural draught boilers.

Not even fan flued!

Just as well you only repair boilers Chris!
