I've just had a new WB greenstar 30CDi fitted, which I'm pleased with
in terms of operation.

There's just one part of the installation which I've noticed looks a
little odd to me - the flue on the outside appears to be ever so
slightly inclined upwards - probably no more than 5 degrees off
horizontal in truth.

Should I be concerned? Or is this the way it should be? I'm
imagining that some rainwater could come through there, but I also
imagine that the flue is designed to handle some condensation in there
so water ingress ought not to be a problem.

I will obviously get the bloke back if it isn't right, but he could
just tell me that's the way its supposed to be, and I'd not be able to
contradict him. So I'd like some guidance first if possible.

Many thanks!

Googling gives

http://www.worcester-bosch.co.uk/hom...uing?flue_id=2

Which confirms:

The concentric flue system must be inclined at 3º (50mm per metre) from the
appliance, to allow condensate to drain back into the boiler.

Think they're all like that - to prevent condensate dripping out of the
flue.

Read the instructions/installation guides left for you. It is correct.
Why do complete idiots always ask such questions. What would you
do if loads of people said it was wrong? Call the man back and say
it was because people you don't know on the internet said so?
Please use common sense.

why flame someone for asking a question, that's what the newsgroups are
about, its only obvious if you know the answer

Oh come on, it's a reasonable question if you don't know anything about
boiler installations. It's not exactly among the daftest of questions
asked here, now is it?

And in any case, if it had been me and "loads of people" in uk.d-i-y
said something was wrong, then that would be good enough for me to raise
concern... it may have escaped your notice but the (sensible) replies
received were accurate.

I could print the entire instruction leaflet left for me which would
show you that there is nothing about the flue in there, but I doubt
you'd be bothered to read it.

I asked a simple question which no-one was under any obligation to
answer. I asked it because I didn't know, and none of the information
left for me contained the answer. I hadn't tracked it down on the
internet either, and as I have never installed a boiler in my life,
and the previous flue appeared horizontal I thought I'd ask a group of
generally knowledgeable people (politely), and if I got an answer I'd
consider what was said.

I don't have to "know" the people that post to uk.d-i-y to know that
a) they are knowledgeable and b) they are usually friendly and
helpful. For example, see Dave P's response - all that I needed to
know so that I could rest assured that what looked like something
wasn't fitted properly was actually the job being done properly.

So, insofar as I'm being referred to as an "idiot" by you, get stuffed
- if you have nothing useful to say, why bother typing.

To others who have been helpful, many thanks.

It will be in the installation/servicing instructions.
It is a legal requirement that these are handed to you
by the installer. You should keep them and pass them on
to any new owner of the boiler in the future.

You're right, of course, that the installation details etc were handed
over. But I am a humble consumer, so I haven't read the installation
instructions - taking the view that I don't need to know the details
or wiring diagrams, though possibly Ian was slightly correct in that
there would be reference to the flue fitting in there.

In fact, the consumer's usage instructions are very sparse in this
particular boiler - it doesn't even tell you what the digital
temperature read out is actually measuring, or what to look out for
(apart from error codes, obviously).

Anyway, I'm resting assured now that the fitting is right (as I
suspected) and I shall steer clear of young Ian in future.

The fitter ought to have left the install and service manual as well as
the user instructions (note some boiler makers seem to place them at the
back of the user guide - so depending on which side of the book you
start from as to what you get!)

IIUC most if not all condensing boilers should have the fluw installed
like this.

If rain were to get into the boiler, then it ought to get fed out via
the condensate drain along with the condensate - there are after all
designed to collect liquid from this source.

So, insofar as I'm being referred to as an "idiot" by you, get stuffed
- if you have nothing useful to say, why bother typing.

Don't worry about Ian, he seems to be a waste of good oxygen but
obviously likes acting like a complete ****. He is the same on every
group I have seen him on.

Normally, I wouldn't post a "me too" like this, but we have just been
through the same process and are still recovering from the by-products
of CH replacement, with the whole house still in chaos after moving
stuff to give access to pipework, radiators etc.

I have all the boiler paperwork, and have only had time to glance
through it, but could well have posted here to ask the original
question. As a long-term news-group junkie (although only recently
here), it's usually easy to sift the helpful and sensible answers from
the others, as it was in this case.

There is, of course the ancillary question about why, if it's a
condensing boiler, we see so much 'steam' from it. If it were condensing
fully, surely we should see no visible exhaust. Are we losing huge
amounts of latent heat here? Is a second stage condensing process worth
looking into?

It's water vapour - not steam.

You can't see any steam from it - steam is invisible.
You see the water droplets as a result of condensing the steam.

If you were to Read The Friendly Manual (which came with the boiler[1])
you'll see it instructs the installer to position the flue so it slopes
back to the boiler at an angle of about 3 degrees, so that condensation in
the flue runs back into the boiler and is collected with the the
condensate produced in the boiler itself and is discharged into the
condensate waste instead of dripping out of the flue onto whatever lies
below.

[1] if your installer hasn't left the boiler and flue installation
manuals with you *then* get him back.
