gas pipe in stub wall battened off

[Riley26]

But a backing batten is needing to properly encase the pipe?

 

[Dan Robinson]

he said to just put a batten either side if you put a gas pipe

But as I was intimating - there is either side, and then their is either side.

Gas inspectors don't know everything either.

The key - and most important thing to learn early on is that you will never know everything, but you need to know where to find it and how to ask for it.

Problem at the moment is a lack of places to ask. Suppose once I get qualified this will change. I see what can I done about this pipe tomorrow. Haven't really made a mistake just not had the training in gas yet.

 

[Riley26]

Thanks that picture explains it more

I have heard the metalic protection is not used much though?

Once you have ACS there is the Combustion Chamber here. There are also other online resources. Within reason people will help you in the open forum here, but gas advise is restricted on the grounds that it is not for a single person's eyes - thousands of people read this forum daily so what one person might act upon responsibly might then be abused by some other person leaving the forum owners and the contributors open to legal issues.

It isn't - and isn't universally demonstrated in the standards. However, it is there to prevent physical harm. We are more concerned with explosive mixtures here. A leak can be repaired. An explosion can not be undone.

Thanks. Without the backing piece the area the pipe runs in will be too large. Is a 3x2 stud wall so maybe 2x2 behind it will do. It is for a gas fire that may or may not go in. It hopefully won't. And this pipe would come redundant. I.e not connected up to the gas.

But the use of a backing piece to encase the pipe is defferntly needed?

Riley - you have a link in your message box - use it wisely.

It's all about the volume IMHO. Perhaps one of the others would like to confirm.

 

[Riley26]

Thanks for he inbox I will do some reading.

 

[Riley26]

Can any one confirm about the backing piece? I guess it is needed

Provided the cavity in which a leak of gas could cause an explosive mixture is small enough that the energy from that volume of explosive gas is small enough to not do serious damage then the possibility of a leak into that cavity seems to be acceptable.
