I'm interested in this comment - my ancient cast iron boiler is flued
through the chimney in the middle of the house - with the terminal
standing about 200mm above the top of the chimney (rough guess - I
haven't been onto the roof to measure it). We often use the open fire
during the winter - is this something I should be worried about?
Also, I'm planning to replace the boiler in the next year or two, and
had imagined that we'd retain the same flueing arrangement (although
with a new flue)- is this going to be a problem?

It may be that the chimney stack is constructed with several flues -
this is typical in older properties - for example to connect from the
separate rooms upstairs and down.
Normally a conventional flue, where passed through a chimney stack is
hooked up using a flue liner (flexible metal tube) all the way to the
top. As long as this is passing through a separate flue way to that
from the open fire, then it's fine. Presumably the smoke from the
fire exits via a different pot, in which case it will be separate.

Hmm. Could be, I suppose. I'll have to check. But somehow I doubt it -
the fireplace is a 2m wide inglenookleading to a pretty large chimney
without any pots on. When we queried adding pots to stop rain coming
down the chimney (which isn't actually that much of a problem, it
turns out) our chimney sweep explained that we'd have to reduce the
opening and use a smaller fire basket, etc.
The boiler's flue is a large-ish (150mm, say) steel pipe which
disappears into the chimney. I have no idea what connects it to the
terminal but I had assumed it was the same, rigid pipe all the way.
I can see I need to look into this rather more seriously. AFAIK the
boiler was installed in 1989 - have the requirements changed since
Presumably the smoke from the
As I mentioned before, no pots. I think I may need to have a good look
up (or down) the chimney
PS I realise that this won't thread properly, but google groups is v.
slow to update and I expect to be on my way through the door shortly.
