Joining the boiler discharge pipe and condensate pipe

[Steelmasons]

Some boiler manufacturers incorporate an air pressure switch (burner interlock) in order to detect loss of trap seal @ condensate outlet.
I can't say that I've ever encountered flue gas condensate discharging into a tundish???.

 

[Terrywookfit]

There will not be a tundish on a condensate system!!!

Viessmann recommend that the condensate is discharged into the waste system internally via a Tundish or washing machine trap !!!
The Gassafe inspector was quite happy on the two installs I took him to !!

Apeendix C in www.planningportal.gov.uk/uploads/br/BR_PDF_PTL_CONDBOILER.pdf shows where an air break in needed in the condensate pipe ( depends on seal depth in boiler )

Which was ??

It's in the title

Sorry about that. It was cut and paste that bought over the formating as large and bold.

Interesting reading that, it is 11 years old though and is written from a building regs perspective rather than gas I would say. What's more interesting though is the boxed paragraph at the bottom of page 4.

As @Terrywookfit example shows though if it's in the MI then that supercedes all regardless of opinion, which it why it's a grey one IMO.

No disrespect Bernard but why do you feel the need to give advise on matters you know nothing about??
What boiler manufacturer recommended the fitting of a tundish to aid in condensate removal?
A tundish is usually fitted in order to alert the end user of a potential problem...

It can also be an air break :-
1) to prevent back flow into the equipment that is draining via the tundish.
2) to prevent low air pressure in the drain system sucking water out of the trap in the boiler.

If you had a tun dish after the trap and the trap dried out poc would be discharged.a tundish is a warning device usually to show overflow or dishcharge.In some cases you could fit them but you would have to have a deep trap on the boiler.

I see that you claim to be Scottish in your profile, but surely even a Scotsman would not turn off a boiler long enough for the trap to dry out !!

It would refill before any fatalities occurred.

Now now terence no need to be like that he he

 

[PullerGas]

The Google Warriors etc didn't think or know about a 'Hotun'.

How can someone that's not a RGI be permitted to advise on a gas boiler & its flue system etc.
Why has Bernardgreen not been banned for giving Gas Work advice to DIYers??

That's a racist statement, please retract it.
