2.1 Boiler Position
The boiler must be installed in accordance with the rules in force of
the countries of destination.
The boiler is not suitable for outside installation.
Any electrical switch or boiler control using mains electricity must be
positioned so that it cannot be touched by a person using a bath or
shower.
The boiler must be mounted on a flat wall which is sufficiently robust
to take its weight, refer to Table 2.
If the boiler is to be fitted into a cupboard, compartment or unusual
location, special procedures are necessary.
Make sure that the cupboard or compartment air vents are positioned
to be clear of obstructions at all times, refer to Section 3.7.
2.2 Clearances
The boiler should be positioned so that at least the minimum
operational and servicing clearances are provided, see diagram
2.1.
Installation Clearances
For rear flue installation the dimension between the boiler mounting
wall and a permanent facing wall must be a minimum of “X”, see
diagram 3.1 and 3.3, plus 272mm.
For side flue installation the dimension between any adjacent
permanent walls must be a minimum of “Y”, see diagram 3.2 and
3.3, plus 332mm.
For flue installations where internal clearances are not practicable,
then external installation will be necessary.
Note: If the appliance is to be installed in a building where access
to the outside is not possible, due to height or other restriction a
internal flue installation kit is available. Part No. 452481.
This includes a larger wall sleeve (150mm dia.) which allows the
flue terminal to be inserted through the wall to the outside of the
building.
For a wall thickness up to 300mm, provided there is sufficient space
available, the flue can be fully installed from the inside.
For a wall thickness over 300mm the external flue hole will need to
be made good from the outside.
If there is insufficient clearance the flue can be installed from
outside.
