60 or 90cm extractor hood for a 5 ring gas hob?

paddy147

Quick question for you all.

I have a 5 ring Belling gas hob,its 70cm wide.

Do I fit a 60cm or a 90cm wide stainless extractor hood over it??
I have 100cm between my wall presses.

So what size unit is best for the gas hob?

Many thanks.

The installation of domestic gas cookers – New British Standard

Feedback from kitchen designers and installers indicated that there has always been a problem with maintaining the combustible free zone around a cooking appliance. For hobs, this now takes the form of an inverted ‘T’

The reason for this change is that, for example, where a 600mm wide appliance was installed in conjunction with a cooker hood, the hood itself would also be 600mm wide. If the guidance in the previous standard was followed correctly, a gap of 50mm should have been left between the cooker hood and any wall unit on either side.

The new guidance still has this 50mm requirement measured from either side of the hob, but this now only extends up to a height of 460mm. This then allows a cooker hood to be fitted at a minimum height of 760mm (unless stated otherwise by either the appliance manufacturer or the hood manufacturer), but the hood needs to be the same width as the appliance being installed (i.e. 700mm wide hob, 700mm wide cooker hood).

sorry comp crashed -meant to say that was copied and pasted

hood can be wider than 700 but should have 50mm gap left each side

main thing to consider is ventilation ,if your hood is extracting air you must replace it by venting the room as gas hob will be burning air also and leaving co2 - i cant see a vent hose left in the picture will you just be recirculating the air ? if so you will need the carbon filters

It will be a recirculating hood.Theres a normal vent in the kitchen on the back kitchen wall next to the window.

Thanks for the advice.:)
