My kitchen is 10.3 m^3 (carefully planned to fit), has no windows at
all (just a door into the hall), and I intend to install a gas hob
there next week.


I also intend to have a gas combi boiler there,
fitted to an external wall, with the flue going through it to the
outside.

If you have an external wall can't you jst fit a vent - like the @kin great
hole they knocked in me lynge when I had a back boiler fitted
