Timber Framed Buildings
If the boiler is to be fitted in a timber framed building it
should be fitted in accordance with the Institute of Gas
Engineering document
IGE/UP/7:1998.
Bathroom Installations
This appliance is rated IP4X.
The boiler may be installed in any room or internal
space, although particular attention is drawn to the
requirements of the current IEE (
BS. 7671) Wiring
Regulations and, in Scotland, the electrical provisions of
the building regulations applicable in Scotland, with
respect to the installation of the boiler in a room or
internal space containing a bath or shower.
If the appliance is to be installed in a room containing a
bath or shower then, providing water jets are not going
to be used for cleaning purposes (as in communal
baths/showers), the appliance can be installed in Zone
3, as detailed in
BS. 7671.
Compartment Installations
A compartment used to enclose the boiler should be
designed and constructed especially for this purpose.
An existing cupboard or compartment may be used,
provided that it is modified for the purpose.
In both cases, details of essential features of cupboard/
compartment design, including airing cupboard
installation, are to conform to the following:
BS 6798 (No cupboard ventilation is required - see 'Air
Supply' for details).
It is not necessary to have a porpose-provided air vent
in the room or internal space in which the boiler is
installed. Neither is it necessary to ventilate a cupboard
or compartment in which the boiler is installed, due to
the low surface temperatures of the boiler casing during
operation; therefore the requirements of
BS 6798, Clause
12
, and BS 5440:2 may be disregarded.
The position selected for installation MUST allow
adequate space for servicing in front of the boiler.
For the minimum clearances required for safety and
subsequent service, see the wall mounting template.
In addition, sufficient space may be required to allow
lifting access to the wall mounting plate.
Wall-mounted condensing gas boilers must only be
operated with the combustion air/flue gas systems
especially devised and authorised for this type of boiler.
Observe the relevant standards, regulations and
legislation of the country of final use.
NOTE
Observe the corresponding technical rules
and the building supervisory and statutory
regulations when installing and operating
the system.
WARNING!
Keep the burner-control unit housing
CLOSED when working on water-bearing
components.
NOTE
It is mandatory to clean and service the
system once a year. This includes an
inspection of the entire system to see if it is
in full working order. Defects and faults
must be eliminated immediately.
NOTE
When instructions aren’t followed, warranty
expires.
CAUTION
Use this device for its intended purpose
only.
