It may not work.

Quite the primary lines of safety are correct combustion, adequate air
supply and a sound flue to remove products of combustion.

Thought gas fires had oxygen sensors rather than CO. A fire will use
the oxygen from a room down to much lower levels than a human can
tolerate.

This is a second line of defence, tha aim is not sense when there would be
insufficient oxygen to support life or combustion but to sense when there
has been some depletion of the oxygen enough to endanger life and turn the
fire off.
