* Free Air Requirement
Air requirement equivalent area. Building regulations Document J, advises that an air supply,permanently open
vents, should be installed for appliances:
If design air permeability >5.0m³/(h.m²) then 550mm²/kW of appliance rated output above 5kW
or
If design air permeability <5.0m³/(h.m²) then 550mm²/kW of appliance rated output
Equivalent air is as measured according to the method in BS EN13141-1:2004
It is unlikely that a dwelling constructed prior to 2008 will have an air permeability of <5.0m³/(h.m²) at 50pa
unless extensive measures have been taken to improve air-tightness.

Carbon Monoxide Alarms
Where a new solid fuel stove is installed in a property a carbon monoxide alarm should be located in the same
room where the appliance is located:
a. on the ceiling at least 300mm from any wall or, if it is located on a wall, as high up as possible (above any
doors and windows) but not within 150mm of the ceiling; and
b. between 1m am 3m horizontally from the appliance.
Carbon monoxide alarms should comply with BS EN 50291:2001 and be powered by a battery designed to
operate for the working life of the alarm. The alarm should incorporate a warning device to alert users when the
working life of the alarm is due to end. Mains-powered BS EN 50291 Type A carbon monoxide alarms with fixed
wiring (not plug in types) may be used as alternative applications provided they are fitted with a sensor failure
warning device.
