Gas Hob air requirements

Mar 21, 2006 8 Replies

I'm fitting a new LPG gas hob (in fact a Corgi guy will do the final connection as required by the B-Regs). The kitchen has not previously had any gas appliances and does not have an air-brick. Since the windows are all modern double-glazed sealed units, the only air input will be under the door from the hall. The current layout has a 12-inch Ventaxia Fan high on the wall (extraction for the electric cooking being replaced) and I had planned to brick this up.



The question: would putting in an air-brick at this high level (5ft above floor) be OK to provide the air input for the Hob/extractor? It will be easy to put a sleaved airbrick in there, and I can duct it to near the burners, plus the height will deter meeces and such.



I guess the alternatives are:



Don't provide an airbrick and let the air come from the house.



Or: Brick up the high level hole and put in a low level air brick.

Have a word with your corgi man or he might not connect it up for you!!!!!

Why do you think cooking with gas will require any less extraction?

I don't know how you got that impression, I'm installing a 150mm chimney hood

700mm over the hob.

The ventaxia is in another corner of the room, and is broken to boot.

I am not concerned with extraction, but in not creating negative pressure and carbon monoxide hence my question was about air bricks and their location.

The reason I ask here rather than asking my installer, is that I don't trust installers, even if they are Corgi registered, so I want to know the answer BEFORE I ask him.

The ventilation requirements for the hob are not likely to exceed that for a cooker. Which in _general_ require

The min hight is 760mm above the hob

Which regulation? The Neff (UK) Ltd installation booklet says 550mm for an electric hob, and 650 mm for a gas one (I have it in front of me now). I can easily make it 760 mm though - and probably will now, thanks.

Thanks, That's just what I wanted. I take it that 'permanent ventilation' means air-brick or equivalent and since you don't say this has to be anywhere particular, my old Ventaxia hole will do.

Quite easily given that you didn't tell us:

But did tell us you were blocking up the existing extraction.
