3 Boiler Location
NOTE:
The boiler may be installed in any room although particular
attention is drawn to the requirements of the current issue of
BS7671 with respect to the installation of a boiler in a room
containing a bath or shower.
Any electrical switch or boiler control using mains electricity
should be so situated that it cannot be touched by a person
using the bath or shower. The electrical provisions of the
Building Standards (Scotland) Regulations are applicable to
such installations in Scotland.
The boiler must be mounted on a flat wall which is sufficiently
robust to take its total weight, see Data Table 1.
3.1 Boiler Clearances
The boiler must be positioned so that at least the minimum
operational and servicing clearances are as shown in diagram
3.1.
Additional clearances may be required around the boiler for
installation purposes, dependent upon site conditions.
3.2 Timber Frame Buildings
If the boiler is to be installed in a timber frame building it should
be fitted in accordance with the Institute of Gas Engineers
document IGE/UP/7/1998. If in doubt seek advice from the
local gas undertaking or Hepworth Heating Ltd.
3.3 Room Ventilation
The boiler is room sealed, so when installed in a room or space
a permanent air vent is not required.
3.4 Cupboard or Compartment Ventilation
Where the boiler is fitted in a cupboard or compartment,
permanent high and low level ventilation must be provided. The
ventilation areas required are given in Table 4.
Where the installation of the boiler will be in an unusual location,
special procedures are necessary, refer to the current issue of
BS6798 for guidance.
Make sure that the cupboard or compartment air vents are
positioned to be clear of obstructions at all times.
A compartment used to enclose the boiler must be designed
and constructed specifically for this purpose.
The doorway opening should be of sufficient size to allow for
easy removal of the boiler.
