8 Mounting boiler frame
Install the boiler in a boiler room in accordance to the actual local regulations BS5440-2:2000.
The installation location of the boiler has to be, and remain, frost-free. The boiler casing is splash water tight
(IPX4D) and is suitable to be installed in e.g. a bathroom.
It is NOT necessary to have a purpose provided air vent in the room or internal space in which the boiler is
installed. Neither is it necessary to ventilate a cupboard or compartment in which the boiler is installed, due
to the extremely low surface temperature of the boiler casing during operation. Therefore the requirements of
BS 6798, Clause 12, and BS5440:2 may be disregarded.
