If you don't leave an air gap asper mi then theres no warranty if the condensate backs up and damages the boiler (on a cold day)
 
I already posted an extract from the BS in post 31 with the relevant diagrams.

Since you are familiar with Logic's if you read page 23 of the MI's you will find this
View attachment 14826

and read page 7 and it says this as do almost every other MI out there

Detailed recommendations are contained in the following British
Standard Codes of Practice:
BS. 5440:1 Flues (for gas appliances of rated input not
exceeding 70 kW).
BS. 5440:2 Ventilation (for gas appliances of rated input not
exceeding 70 kW).
BSEN. 12828:2003 Heating Systems in buildings: Design for
water based heating systems.
BSEN 12831:2003 Heating Systems in buildings: Method for
calculation of the design heat load.
BSEN 14336:2004 Heating Systems in buildings: Installation
and commissioning of water based heating
systems.
BS. 5546 Installation of gas hot water supplies for domestic
purposes (2nd Family Gases)
BS. 6798 Installation of gas fired hot water boilers of rated
input not exceeding 70 kW.

BS. 6891 Low pressure installation pipes.


Logic doesn't show tundish or open cond pipe? Ahhhhh but it does show cond above water trap! Devil is in the detail!!!

When I did my first boiler install I ran a condense into a rainwater gutter. As it was me first when it got inspected the guy (Alan Mathews) said that if the gutter got blocked you'd get corrosive water running down the bricks causing a problem. As it happened I'd fitted a neutraliser anyway so he said it was fine but in any case he wouldn't write it down as any fault at all. He said it was a non gas related issue.

this situation is slightly different, but as others have said IF the trap was empty when the boiler fired up it would take a very small amount of time to fill up again anyway. I would say NCS, and yes i feel sorry for anybody who has their boiler disconnected for that...
 
Been to isar ruined as down pipe was blocked, roof tried to empty via burner in boiler, 3 visits later new boiler as it was dry when visited looked at water damage on fan and it twigged! Don't use rwp! Without air gap .

I got to page 6 and got extremely bored, so skipped to this page. So you had Alan Matthews round, correct in what he said. You should not discharge into rainwater or land course without neutralising the condensate. Further to this, if the rainwater became blocked and or backed up due to heavy rain this would cause problems with the boiler unless there is an air break in the pipework. Tamz is spot an as usual with this thread.

You may think that dear boy, but you're wrong. But thanks for taking the time to express your views.
 
When the experts can't agree, it undermines all their credibility. That why you should use the "because" word In any technical comment you make. For example The condensate Pipe should ????? "BECAUSE" Section? of manufacturer instructions and Section ? of British Standards require it to be this way.

Dickie, can we help you here at all? Would you like to share with us what’s bothering you? Insecurity? You don’t sleep well? You need help? I’d say, it’s not about condensate pipe, it’s much deeper… We might be able to help you, if we can... You might have a condition - Asperger syndrome. Do you believe that you are much more intelligent than everyone else here? Or you are just stubborn and have a bit of an ego. What causes you to be this way?

This thread is getting silly now. Also not suitable for open forum so I'm banging it into the private forum.

Everybody please get back on subject or I'll close it.

Thought subject was clearly closed by reg man? Only time it would be any different is if boiler didn't have a 75mm water trap?
