Flue terminal legal? (pic)

its a puma, no MI. However ACS rules are 300mm all round but that doesnt include the adjacent wall as more chance of fumes entering especially a door!

Never been any good with this, too many variables for them to put it on paper.

This is a situation where the written regulations catch people out because they have to THINK and reach a conclusion.

Most MI requirements say a mimimum of 300 mm from any opening into the building.

But wherever its fitted it must not cause any danger or inconvenience!

That requires a judgement!

thanks guys.

Tony the boiler that actually concerns me is a Vokera Flowmatic with very similar terminal arrangments. Landlord has asked for my opinion on the heating system (so i can repair if necessary) and also any problems likely to arise when a LGSC is done.

If this really is left to judgment then im satisfied my concern really was the fact i wasn't sure and had no way of confirming. Despite a 2'' thick gas reg book.
 
Looks AR as a minimum and possibly ID since the boiler will be breathing its own combustion products when the door is wide open and up tight against the terminal; also possible combustion of the door.
 
So if the flues only 10mm from the glass with the door open its still only NCS?

Don't agree.
 
Thats the problem! It required judgement and thats a variable personal issue.

I would say that its OK when the door is closed becoming AR if the door is opened to block the flue completely.

However if the door completely blocked the flue outlet then the APS would shut off the boiler.

Looks like the door will hit the blob on the soil pipe, so OK, becoming ncs when door open. Therefore installation is ncs.

Ncs for under 2m with no terminal guard already chris.
 
You're right of course, I should have said I don't think the situation makes it any worse.
 
When the door is open it becomes in effect an opposing wall which should be at a minimum of 600 mm in front of the terminal!

The 600 mm is the default distance and can be changed if the manufacturers choose to.

I do disagree with 600 mm being sufficient in some cases. Last week I saw a premix boiler discharging into the middle of the neighbours opposing wall only 600 mm away. On a still day that narrow passage will become seriously deficient in oxygen and affect the combustion.
