Vertical condenser flue

[Best]

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?

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.

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
