I need to provide an appropriate amount of ventilation for an LPG hob
in my kitchen. The cooker is close to french doors in the garden, and
my plan is to have 2 or more smallish vents put in the wall above the
doors (comfortably 2ft of space between the top of the doors and the
ceiling.

I've seen some dark metal cowls for the interior of the vent, a sort
of a quarter of a sphere, or like an elbow joint to that the opening
faces downwards. Unfortunately I can't remember where they were (I
have vague memories of a Screwfix leaflet, but I can't find them on
the website).

Anyone have any recommendations? preferably dark / anthracite / case
iron looking, but brushed/stainless steel at a push.

A bit of a follow-up, and different but related question.

The first (large) quote I had for this specified that the room would
need extra ventilation/airbricks at an area of about 1' square. Didn't
ask about the suze of the room etc.

A second quote had a look at the room and said additional ventilation
was unnecessary. I double-checked the installation manual, and it just
says that the hob must be installed in accordance with BS5440.

My reading of the bits I could find of these regs. is that for the
size of room in question, additional ventilation is unnecessary for
anything over 20m3

The kitchen is 6m x 3m x 2+m high for a grand total of 36m3. It has an
"openable" window and double french doors, and is connected by an open
arch to another room, about 3m x 4m x 2+m. I make that another 24m3
for a grand total of 60m3.

From that lot, it seems to me that additional ventilation would be
unnecessary? I've tried to find a downloadable copy of BS5440, but no
joy.

Is that what they actually said? Usually you would quote ventialtion
grille size in a free air space term. 1' square would basically be a
1' square hole in the wall, or an open window. Tad excessive, or
someone doesn't know what's going on.

To be fair, I wasn't party to that exact conversation, so it may be
Chinese whispers. The second engineer said no additional ventilation was
needed, and is finishing off tomorrow, so hoorah.
