Boiler installer left old flue hole open

[fixitflav]

Does not look like much of a fall on condense pipe, no clips or insulation as per regs

You beat me to it! It would have been just as easy to give it a decent fall. But the sleeve on the flue, and the filled hole look nice.

no clips

Hopefully, the photo was the unfinished job, with clips still to be fitted. If that pipe fills with water, the sheer weight pull it down.

That flue, on the floor below, looks awfully close to the window directly above it.

They seem to have come back today to finish the work. Does this now look compliant with regulations and a decent enough job (leaving aside the issue of distance between the flue and window)? Perhaps @CountryFan @Harry Bloomfield . Thanks again for your perspectives.

Well, the hole is fine. Did you ask about the distance from the soffit ventilation? The condensate pipe isn't insulated either.

Thanks for the replies. I looked at the manufacturer's instructions here and they do say there should be a fall of at least 45mm/m and the pipe should be insulated. I will take that up with them. However there doesn't seem to be a requirement for supports along the length, nor in other regulations that I could find - is there a particular place that would stipulate that and apply here?

Not yet explicitly, but whenever I ask about anything I get the reply that they are Gas Safe certified and everything is in compliance, and I imagine that that is what they'd say until there's evidence to the contrary.

Yes have tried to cut corners and left it unfinished without talking to you about it.

Also, if you have the manual and it's the same as I've just looked at, look at Q of the flue termination section and using a neutraliser for the condense (section 7).

There is little, if any obvious fall.

Common sense, dictates that it needs to be adequately supported. Once that pipe gets condensate in it, it will be much heavier, and the heavier it gets, the greater the droop, the heavier it will become, with an eventual complete collapse.
