Where a fuel-burning appliance has an extended and/or concealed flue, an apparatus
should be installed in each room through which the flue passes.
Additionally, the installation of carbon monoxide alarms is recommended to prevent from
unnoticed spread of CO from the biofuels storage room to other parts of the building. In
this case the carbon monoxide Alarm should be installed outside the storage room, but in
the immediate vicinity – ideally near the access door.
Boiler rooms are often located in areas of a building that are normally not frequented very
often, and so are the fuel storage rooms. Consequently, an audible alarm of the apparatus
may not be heard in other parts of the building. For this reason, it is recommended to
connect the apparatus to other warning devices in the building and to attach at least a
visual signalling device at the entrance to this part of the building, which is activated by the
apparatus if it is in alarm condition. To ensure a reliable activation of this signalling device
a Type A apparatus (see EN 50291-1:2018, 5.9) should be used.
