3 Boiler Location, Clearances and Ventilation
3.1 Location
This boiler is not suitable for outdoor installation.
This boiler may be installed in any room, although particular
attention is drawn to the installation of a boiler in a room
containing a bath or shower where reference must be made to
the relevant requirements.
This boiler is suitable for installation in bathroom zones 2 and
3.
In GB this is the current I.E.E. WIRING REGULATIONS and
BUILDING REGULATIONS.
In IE reference should be made to the current edition of
I.S.813 “Domestic Gas Installations” and the current ETCI
rules.
3.2 Clearances
The boiler should be positioned so that at least the minimum
operational and servicing clearances are provided, see
diagram 3.1.
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 diagram 3.1.
3.3 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. If in doubt seek advice
from local gas undertaking or Glow-worm.
3.4 Combustible Material
The boiler and flue are suitable for installation onto and
through combustible materials provided that:-
1) The boiler must be sited at least 1m away from flammable
materials and heat sensitive walls must be protected by
appropriate insulation.
2) Minimum 5 mm clearance is maintained around the
circumference of the flue (air intake).
3) The combustible surface and fixings are suitable for
supporting the load.
4) The minimum clearances from the boiler case are
maintained.
3.5 Room Ventilation
The boiler is room sealed so a permanent air vent is not
required.
3.6 Cupboard or Compartment Ventilation
If the boiler is installed in a compartment there must be
purpose made ventilation for cooling purposes.
Make sure 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.
An existing cupboard or compartment modified for the
purpose may be used. Refer to the current issue of BS6798
for guidance.
