Question Help - how to deal with rain water entering the flue

During the recent heavy rain in the UK I have had 2 separate instances of my Ariston combi-boiler shutting down because of water entering the flue.

I had to call out an engineer which is annoying and inconvenient in terms of time off work to be home. I'm sure it's a simple fix (at the boiler end, not the flue end - I know I'll need to look at that too....)

Can anyone advise what needs to be cleared / drained / dried / opened in order to let the pilot light fire up again???

Thanks in advance

Water in the flue, you say!

Mozzer,

Retire and move to the south of France.

What kind of flue? Where does it terminate? What kind of Boiler( condensing
or non-condensing)? Steam? What kind of termination cap on the flue?

Sometimes we Yanks are a bit much to put up with. But I will look up the
boiler on google unless you can give me a dot com. Is it a UK brand?

Probably maufactured from a "32" Austin-Martin.

Say goodbye, Homer. Goodbye

Rain Woes

Mozzer,

I looked at your boiler on Google and I was wrong. It is a "36" Austin-Martin.

No, no, nice looking unit. Europe has been far ahead of the Yanks in this design.

I assume that the vent is horizonal side wall venting. An that wall faces the
North Sea, so that the wind driven water flows into the flue.

Shield the vent. 4 inches above the flue screw a half round piece of metal
that is about 6 inches longer than the flue to the wall. It will act a kind of
a roof over the flue and shed the rain around the flue and keep water from entering it. Is the flue termination cap mounted the right way up?
Usually these things are water tight. Say goodbye, Homer. Goodbye

Rain down the chiminey?

I get it. It makes a lot of noise but it doesn't seem to be a problem.
I think maybe because the boiler is not directly under the flue, the
elbows and horizontal pipe are usually hot enough to evaporate it.
Also, with the new boiler, I have an automatic damper, which would
probably be warm enough from the constant pilot. Of course,
when the boiler is firing, water would never reach it.

I guess constant pilots have advantages. Up to now, I was thinking it
might be nice to have an auto pilot(not the aircraft type).
