Whatis it that you are trying to monitor?

Invariably when I see these they are installed along side room sealed
boilers, where the possibility of serious amounts of CO entering the
room is very remote indeed.

They should only ever be used along open flued appliances or flueless
appliances. They are not, absolutely not, a substitute for regular and
conscientious maintenance.

In the same room as a Baxi Bermuda 'fireback' boiler. Not trying to cut
down on maintenance, just trying to head off anything nasty (fatal?) if
there's a 'problem'.
