A very good call Transam son, i'm not saying one way or another, I just want to hear your views.

from floor to floor and not in a duct i think there has to be some sort of fire stopping material used, i remember reading this a year or so back,

 

[dwbbill]

Oh, just before someone says; 'Better to debate this in the combustion chamber'. ****abuse deleted**** CC/CCCs & CPSs got me banned from there!!

So, any points on boiler repairs or gas related views I may have, I can only express them here.

who is cc/ccc etc

I think you may find Bill, some LABC officers may view gas pipes run between first floor joists as indeed a duct & should be vented accordingly!!
We have also had NHBC inspectors spouting the same drivel.

Yes, can & worms springs to mind!!

[Biggles..]

Let's see if some of the old guard can teach the cc's something about sleeving.

22mm copper gas line,what size sleeve if using copper.

Serious question.

to some people a duck is a duct, but in this case the space between the joists and the supports could be considered as a duck and prob should be, although i cant remember ever seeing a vented floor space.

Well Delta T has asked the question !!

Sleeves can be made of steel , copper or a suitable fireproof plastic !

Reg 19 deals with sleeving (2) states No person shall install any installation pipework so as to pass through a wall, floor or standing of solid construction (wether or not it contains a cavity ) from one side to the other unless
(b) adequate means are provided to prevent so far as is practicable , any escape of gas from the pipework passing through the the wall , floor , or standing from entering any cavity in the wall , floor or standing !!

19 (1) No person shall install any pipe work ect ect unless it is protected against failure caused by movement ect




There is no requirement as I understand it to sleeve pipes that are drilled through joists !!!

A stud wall would come under the heading of a standing , therefore the pipe would need to be sleeved , not for protection from the building ?? but because of a potential gas leak ?? into what would be classified as a cavity or unventilated space !!

 

[transam]

Incidentally factory sheathed pipe which includes space between the internal & external sleeving need not be sleeved , these spaces were refered to as interslices , normally came as 10mm soft copper !!
