6 Boiler Location and Ventilation

6.1 Boiler Location

The boiler may be installed in any room although
particular attention is drawn to the requirements of the
current issue of BS7671, IEE Wiring Regulations, the
electrical provisions of the Building Regulations
(Scotland), and in IE the current edition of IS 813 and
the ETCI rules, with respect to the installation of a boiler
in a room containing a bath or a shower. Any electrical
switch or boiler control using mains electricity should be
so situated that a person using the bath or shower can-
not touch it.
The boiler must be mounted on a flat wall, which is
sufficiently robust to take its total weight. The boiler
may be installed on a combustible wall, subject to the
requirements of the Local Authorities and Building
Regulations.
The boiler is not suitable for fitting outdoors.

6.2 Clearances

The boiler should be positioned so that at least the
minimum operational and servicing clearances are
provided, see Fig. 6.1.
Additional clearances may be beneficial around the
boiler for installation and servicing.
For flue installations where external access is not
practicable, consideration should be given for the space
required to insert the flue internally, which may
necessitate clearance larger than those specified in
Fig. 6.1.

6.3 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.

6.4 Room Ventilation

The boiler is room sealed, so when it is installed in a
room or space, a permanent air vent is not required.

6.5 Compartment Ventilation

If the boiler is installed in a compartment, a permanent
air vent is not required.
Leave existing air vents.
