Mounting the boiler
The room where the boiler will be placed must always be 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.
The boiler can be mounted practically to any wall with the suspension bracket and the
enclosed fixing equipment. The wall must be flat and of sufficient strength in order to be
able to carry the boiler weight with its water content.
Above the boiler there must be at least 250 mm working space in order to be able to fit a
coaxial flue system or a twin supply. On the left side of the boiler at least 50 mm and on
the right side 10 mm must be reserved to allow fitting or removing of casing. The location
of the boiler can be determined by using the template.
Before hanging the boiler remove the outer boiler casing. The cover is also the air cabinet
and is attached to the rear wall with four quick fasteners (A, B, C and D) (see figure 1).
Secure the quick fasteners with the screws (A, B, C and D) at the back of the
cover.
Lift the boiler only by the boilers rear wall.
Lifting and carrying precautions:
-
Lift only a manageable weight, or ask for help.
-
When lifting the boiler, bend the knees, and keep the back straight and feet
apart.
-
Do not lift and twist at the same time.
-
Lift and carry the boiler close to the body.
-
Wear protective clothing and gloves to protect from any sharp edges.
