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) Minimum 5mm clearance is maintained around the
circumference of the flue (air intake).
2) The combustible surface and fixings are suitable for
supporting the load.
3) 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
Due to the high efficiency and low casing temperature of this
boiler, cupboard or compartment ventilation is not necessary.
• Existing ventilation should be investigated for its purpose
before removing.

3.7 Airing Cupboard Installation
If the boiler is to be installed in an airing cupboard it is not
required to separate the boiler with a non-combustible partition.
However, installation and servicing clearances must be
maintained, and the boiler kept clear of any clothing. Details of
essential features of cupboard/compartment design including
airing cupboard installations are given in BS 6891. In IE the
current edition of IS 813.
3.8 Roof Restricting Installation
It is not necessary to ensure sufficient clearance between
the boiler and combustible materials or components. This is
because the temperature of the boiler will always be less than
85 o C due to its nominal heat output.
