Gas safe engineers

[Gromit]

Just in the planning stage of a kitchen for a customer and need a quick answer. I usually ask the gas enginner that we use but he`s away on holiday(again).

Are there an specific requirment for channeling a gas pipe (15mm) down a wall, similar to cable zones are for electric cable.

Any help?

gas pipes should be sleeved in walls, but rarely are.

I know about the sleeving in plaster and walls to prevent corrosion but its the location thats the query. The pipe thats in the kitchen at the moment is exactly were the duct for the cooker hood is going to go, so will have to get the pipe moved. The customer doesn`t want any pipes boxed in so it`ll have to be channeled up the wall. I`m trying to figure out where it can go so it doesn`t interfere with wall unit fixing or such like.

Pretty sure any boxing, covering or burying of gas pipes in the building fabric is a no no as you cant then check the condition of the pipe or inspect for leaks etc.  

But... I'm not a Gas Safe engineer so hopefully someone with better knowledge will be along later to confirm.

It is not recommended at all to chase in a gas pipe but if you do it must have at least 25mm cover.

If you do.................

1) Its unseen and unnaccesible

2) Its at risk of damage by drilling etc by someone later on who doesnt know its there

3) There is a real risk of corrosion (then hidden)

4) A chase is a duct (potentially) and can duct leaking gas under pressure to where you dont want it

5) To duct it (box it in) will require adequate ventilation

6) It should be a coated pipe with no joints

Having said that, proper pipe in (steel) pipe with sealed ends is the best way.

As you are fitting a cooker hood, I assume that it is an outside wall?  If so just whip the pipe outside in the ceiling void and bring it back in below the work top. Job Jobbed.

Thanks chaps for the replies. I`m going to play safe and tell the customer the pipe will have to run down the corner of the wall on the surface and have some boxing in around it to blend it in with the wall units.
