Vertical condenser flue

[cab50]

quick question, does a vertical condenser flue need to have a rain cap or as it is full of steam which I assume must condense at times, does it drain anyhow?

Thanks

Why do you ask ?

Why do you ask ?

My elderly dad had his flue changed to go vertical out of Garage roof and it doesn’t have one,
; he switched to condenser and the old vent interfered with his shed.

I was looking to redirect mine, up higher and it made me think if I was not going to have a L pipe to send it sideways what about rain, so I looked at Dads and it made me think.

I was just going to add a plume Management pipe on mine preference vertical exit but can make it go sideways.

Thankd

either way your gas safe or oftec guy will advise the best way

Just google it and compare would be my advice.

Are you talking about a flue or Plume kit ? a proper V/Flue will have a terminal on top can you put up a photo of what's been done

Will get a photo in a couple of days, of my Dads. Is an oil boiler.

As it it an oil condensing boiler your dad now has, and if the vertical flue is proper flue kit for that boiler, - then it will not have a rain cap and does not require it.
It allows the plume to go higher to disperse better.
Rainwater will just go out the condense discharge and can’t damage the boiler.
Some universal flues (non balanced) can be used and are an exception because they can have rain caps, but tend to direct the plume downwards.
None of this information on oil flues is safety related, so I see no reason on it being withheld.
Just make sure any work on a flue to be installed or altered, is done by the relevant oil or gas qualified person.

You do know "You personally" can't just put a plume management kit on it.

Boiler would need to be analyser tested if any alteration to a flue because a longer flue for example might alter the way the burner operates

Vertical flues with no terminal? I must be miss-understanding. This sounds like madness. What about rain water going down the air intake? What about manafacturers instructions? What about regs? What about safety? What about combustion? What about leaving it alone and getting a properly qualified person in?

Universal flue? Are you sure, I've never heard of a universal flue.

Yes, you can get a stainless steel twin walled insulated flue that can be used for some condensing oil boilers, using an adaptor piece for final connection to boiler.
I only termed it universal.
The flue has a groove on the outer part of the internal pipe that rubber seals go onto, much like the actual boiler flue kits have.
Can be used for Warmflow or Grant oil boilers for sure. It isn’t a balanced flue.
I will send you details of it.

Oh, oil, not my thing. Cheers

That’s the way they are made in the factory oil boiler kits. The flue has opening on vertical kits has a stainless steel ‘wire’ sort of thing to prevent a bird falling in. The air intake is on the side of the terminal, similar to gas flues and rain can’t get in there.

google what?

What I ment was google a picture of the relevant flue as some people think it should look like a Chinese hat
