I understand capping can be done just by adding a cap to the top of the pots, so that the chimney is not permanently blocked off. Since they still allow air flow I assume air bricks will not be so necessary ?

I assume balloons are normally fitted to capped chimneys just to stop heat going up them ?

Thanks Joe You think that damp in all three places could be coming from the top ? We moved in 2 yrs ago. The chimney balloons were there already and the damp only seems to have appeared in the last 6 months or so. We do have a de-humidifier, wound't you expect that to remove "normal"...

1916 mid-Terrace. Four internal chimneys - rear ground floor in use, front ground floor & two first floors not in use. Chimney "balloons" fitted. Front ground floor chimney has white furr inside, bubbled paint outside up to 60cm from floor. Moisture meter measures 20-30% in these areas...

It is that exact flue. But you need to get a view of the top of it. The "lid" is an upside cone.

Mmmm, nice suggestions. Think I'll stick with the water gathering in there ! Problem was with a very loud thump as the boiler fired up and a strong smell of fumes just after it fired on warmer drier days. Turned out the mix wasn't set quite right, it was burning rich. Small and thump were...

I saw his photocard, checked him out online, everything ! There's even been a Worcester Bosch guy here because there was something wrong with the boiler. The flue looks just like the photos on Worcester Bosch's website and it came in a box already assembled. I don't think there is anything...

It is condensing and was fitted by a CORGI guy. I've checked on Worcester Bosch's website and the "upside down cone top" can be seen in the photos of the vertical flue. Seems like that's deliberate and it comes like that from Worcester Bosch. I'm just interested to know why !

Had this new boiler installed a few weeks ago and am wondering why the top of the vertical flue seems to be upside down. It's not a normal cone-shaped top. It's an upside down cone shape so water gathers in there. Any idea why it's like that ?

Tony Thanks Installer is definitely CORGI registered. Must admit I didn't check that he is also registered for LPG. He is one of the "official" installers for Worcester Bosch in my area. I checked the flue installation with the instructions and that is all correct. Hard to tell if...

A few weeks on and the problem remains. The smell is of unburnt LPG and lingers around for a good five minutes after ignition. Plumber has re-visited to check the flue and all is OK there. Is there a setting the he should be able to change the amount of gas released before the boiler fires ?

The fumes are outside. Not inside the house or inside the outhouse. The neighbour's heating guy reckons it just needs a taller flue.

Just had this new LPG condensing combination boiler installed into a one storey out-house. Flue is vertical out of the out-house pitched roof. Everytime the boiler ignites I can smell fumes. Is this normal for a new boiler, for LPG, for condensing ?

As far as I can tell the system was properly drained, cleaned and inhibited. Didn't watch the guy the whole time but he's been doing my central heating work for years and installed this boiler for me 10 years ago. I'm fairly confident that he's not been half-doing the work....

You're right it's aluminium. He said something about the copper in the water being from corrosion caused by flux ? He hasn't tried a stethoscope although the sound (including the groan as the pump shuts down) does seem to be coming from the boiler when standing next to it.
