But I'm probably talking ********. I haven't made a concerted effort to
calculate the ventilation requirements of the various things yet so this
will come out in the wash when I do the research properly

The (flueless) gas cooker only requires that there is some sort of opening
direct to outside air. (e.g. openable window).
The log burner does not come under BS 5440 but it would be a good idea to
make sure that it has enough air.

I would suggest (unless some normative document states otherwise) that a
permanent vent to outside air of at least 50cm² should do the trick.



Excellent - thanks Ed.

I have a vent in the room already (put there for the current gas fire/back
boiler).

I'll clean it and measure it, but it looks superficially like it's =50cm2.

I'll have to be a bit careful because there'll be a cooker hood with exhaust
to outside going in too and I'm aware this may load the vent (reduce its
effective capacity) - I'll be sure to check on that too.

Cheers
