I'm just looking for ideas or anything I've missed here....
Kitchen layout is 2m38 x 2m67.
ABC A C -external wall A C
The sink is on wall B in the middle, there's a gas meter on the corner of B and C with an airvent. The airvent is shared by the bathroom fan duct which runs along the top of wall B, but I'm going to reroute this out through the loft (and soil pipe, to be capped with an air admittance valve).
The gas bayonet fitting is on wall A - the only external wall is C. I'd like to add a hood, but the run to the external wall will be about 3.5m with 1 90deg bend and some more mangling where it gets close to wall A A google o n uk.d-i-y suggests that a typical maximum length is 2.5m without any bends. We need to use rectangular ducting to fit over the top of the wall units. Could I survive with a long duct
I could get someone to move the gas point [1] and put the cooker and hood on the adjacent wall (B)to the window. That would be a run of less than a metre to the external wall. That's where the sink is, but I'd like to move the sink onto wall C anyway to be by the window. However, the pipes will then have to run behind the cooker. Is it okay to run upvc drainage pipes behind a cooker? It's not clear to me in any case that there's an easy way to make them fit!
Alternatively, could I run the hood ducting vertical up, into the ceiling (and roofspace) and then horizontally over the top of the kitchen and out through the soffits somehow? Alternatively, 2.5m would get me up to the roof, so can I go straight up and out?
[1] Well, cap it off, and install a new point tee-ed off near the gas meter.
