On Mon, 26 Jan 2004 20:22:33 GMT, a particular chimpanzee named "Matt
G." randomly hit the keyboard and
produced:

We have two roughly 6" square air vents in the kitchen wall, one near
the ground and the other a couple of feet up. There used to be an
oil-fuelled boiler in a concrete cupboard in the kitchen, but now the
only thing that needs ventilating in that room is the gas hob. Would it
be ok to brick up one of the vents, as they're quite draughty, or does
the hob really need that much fresh air?

Provided that the volume of the kitchen is greater than 10m³ (which
would be a very small kitchen), and that you have an opening window,
then permanent ventilation is not required (see AD 'J'
[http://tinyurl.com/292da], section 3.15). You may want to keep at
least one of these vents with a closeable grille to give you some
background ventilation without having to keep a window open.
