Can pipes to combi be chased into a wall.

[cascas]

Just planning a kitchen. Usually a combi fitted into a kitchen has the pipes from the bottom put through the worktop and boxed in. The layout I am working with is a bit of a pain, and I have little choice but to put the dishwasher below planned location for the boiler. At the moment neither can be moved.

As the dishwasher has little (i.e no) clearance behind I cannot plan it to allow the pipes to pass from the boiler to the left hand side of the dishwasher/sink etc. Is it acceptable to chase these pipes (inc gas) into the wall between the boiler down to behind this dishwasher and out to one side.

everything is possible is just going to cost you more

Threaded Black iron for the gas....

You can chase ... A thought though, could you channel them in a duct so they're accessible?

Is copper not used for buried pipes?

Not for Gas...

i always thought it was ok as long as it was protected i.e plastic coated.

Was just thinking about if I could do this, not sure yet. I will chase the wall / allow space for a duct, so that the installer can just run the pipe in the space.

Always used BI on chased work myself, surely you can still puncture plastic coated or similar........
Can the boiler be re-positioned anywhere else ....

Black iron is a good idea but not a legal requirement. B.S. 6891 doesn't even mention protection from corrosion for gas pipes chased into walls.
