(1) In addition, the terminal should be no nearer than 150mm to an opening in the building fabric formed for the purpose of accommodating
a built-in element such as a window frame.
(2) Only ONE 25mm clearance is allowed per installation. If one of the dimension D,E,F,G or H is 25mm then the remainder MUST be as
shown in brackets, in accordance with BS 5440–1.
Important
Under car ports we recommend the use of the plume
displacement kit. The terminal position must ensure the safe and
nuisance free dispersal of combustion products.
If the terminal discharges onto a pathway or passageway, check that
combustion products will not cause a nuisance and that the terminal will
not obstruct the passageway.
If a terminal is less than 2 metres above a balcony, above ground or above
a flat roof to which people have access, then a suitable terminal guard
must be provided.
