CO alarm interpretation of flue

Extracts from the Smoke, Heat and Carbon Monoxide Alarms for Private Tenancies Regulations (NI)

I understand from several contractors who have reported that their wholesaler, with the backing of a well-known national manufacturer of domestic smoke, heat and CO alarms, are contending that CO alarms are also required in rooms through which a flue might pass. That contention seems to be based on the above regulation, 3(1) (c) and the interpretation of "flue" 

It would seem to me to be a stretch of the credible to consider that a ground floor chimney breast without further openings, extending upwards to carry the flue through a first-floor room to the chimney stack outside, would require a CO detector to be fitted in that room. 

I am wondering if anyone has bumped into similar contentions on the mainland.

    I agree.

    The engineering argument might be that a flue could leak. Debris such as a bird's nest, or dead birds, etc. could (partially) block the flue at the top and there might be an over-pressure. On the whole, however, flues suck rather than blow.

    In a moment, Graham will be reminding us that only a judge can interpret the words. In the mean time, I would say that it is the wall which contains the flue and not the room(s) contained by the wall. Put another way, the flue is a cavity within the wall.
