Kitchen extract fan grille location

[Amp David]

Can anyone point me in the direction of where to find the rules and regs on where I can or can't position the grille for a cooker extractor hood, on the outside wall.

Looked at Part F of building regs, but doesn't give any ideas.

OK boss, calm down.

Just seeing, as next door are doing an extension and the builders cored a hole in the side for the ducting to go through right tight in an internat corner.

there are rules regarding distance from flues, gna have a look see what i can find

I know you`re not supposed to core drill within 150mm of a lintel, and there are regs regarding flues I think

I think the regs regarding flues are to do with the distance from windows and doors.

My mate had to get his boiler flue moved last year 'cos it was too close to his back door.

Could this really be a problem?

If it were a gas cooker the co2 output from the cooker is acceptable if no hood is in place or not being used and thus remains in the room. thus no dangerous gas to come back through a window or well up in a corner.

If electric cooker non at all obviously.

The output from the extractor would be mainly steam from cooking in either case.

I think its ok but please correct me if I'm wrong as I would like to know the correct school of thought too.

On the tip of hoods and holes.
Any one know what is acceptable with regard to drilling in proximity to joists to vent out?

I.e never much room above considering the hood has to be 750mm above surface.
I try to place the hole between joists so the structure is not impaired below a joist with a hole.

If the hole had to be near the ceiling and there was a joist directly above?????

I think this could be a good point of call:

Received the latest mag from NAPIT today and they have an article about the very same question and the answer is.......300mm from a flue for a fanned outlet (but this is only a recommendation)

Hi.

I've always been told that a minimum of 300mm is required between any flu /extract grill and an opening window / door. Also, this distance applies between the flu and extract grill.

I suspect there are also restrictions to venting onto the next doors property, where the wall of the house is the boundary
