*** Please note that Building Regulations Document J advises that
additional permanent air supply is required for appliances with an output
of above 5Kw.
With modern properties additional air may be required as Document J
suggests that additional air would be a benefit.
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
If in doubt, please consult your registered installer for advice.
NOTE: Extractor fans when operating in the same room or space as the
appliance may cause problems.
