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 :-) ]
