Plume pipe extension

Mar 08, 2022 Last reply: 4 years ago 3 Replies

Our combi boiler is too close to a couple of windows though I'm fairly sure it's legal. In our last house, when the boiler was installed we had an extended plume pipe fitted.



So I can get such a thing for this boiler. Can I just fit this myself, or would the boiler need some subsequent adjustment involving a professional?



[It's really tempting to connect it to the nearby soil pipe, but I suspect that's frowned upon :-) ]

Typically wants to be at least 300mm from any opening windows.

Have a look at the flue install manual for the boiler (sometimes it's a separate document - sometimes part of the boiler install manual).

A straight extension outside is pretty straight forward. A plume management kit that turns a right angle against a wall before going off elsewhere, may need the existing flue to be shortened first to get the elbow close enough to the wall. Note also that boilers have a maximum total flue length that you should not exceeed.

CO entering the house through a dry water trap does not sound like a good thing! :-)

Clive Arthur used his keyboard to write :

It would need to be installed and checked by Gas qualified engineer.

Not so. The only requirement is that you're competent and not doing the work as a landlord.

In theory only a new boiler fit would involve the LA. Changing a flue in a like for like matter can be done by anyone not taking remuneration, and won't need to inform the LA.
