Caution!
When tightening or slackening screwed
connections always use suitable open-ended
spanners (not pipe wrench, or extensions, etc.).
Incorrect use and/or unsuitable tools can lead
to damage being caused (e.g. gas or water
leakage)!
3.3
Installation site
The location chosen for the boiler must permit
the provision of a satisfactory flue termination.
The location must also provide adequate space
for servicing and air circulation around the boiler.
The boiler may be installed in any room, although
particular attention is drawn to the requirements of
BS 7671 (IEE Regulations), the electrical provisions of
the Building Standards (Scotland) Regulations, and in
IE the current edition of IS 813 and the current ETCI
rules, in respect of the installation of a boiler in a room
containing a bath or shower.
Note!
If a room sealed boiler is installed in a room
with a bath or shower, electrical switches or
boiler controls using the mains power supply
must be placed at locations that cannot be
reached by the person in the bath or shower.
If the boiler is installed in an unusual location, special
procedures may be necessary and BS 5546 and BS
6798 give detailed guidance on this aspect. The boiler
must be mounted on a flat, vertical wall, which must be
sufficiently robust to take the weight of the boiler. The
boiler may be installed on a combustible wall, subject
to the requirements of the Local Authorities and
Building Regulations.
A compartment used to enclose the boiler must be
designed and constructed specifically for this purpose.
(An existing cupboard or compartment may be used
provided that it is modified for the purpose). Details
of essential features of cupboard/compartment design
including airing cupboard installations are given in BS
6798. If the boiler is to be fitted in a timber framed
building, it should be fitted in accordance with Institute
of Gas Engineers Publication IGE/UP/7/1998 "Guide
for Gas Installation in Timber Framed Housing". Please
note the safety instructions below before deciding
where to install the boiler:
Caution
Do not !install the appliance in rooms prone
to frost. In rooms with aggressive steam
or dust, the appliance must be operated
independent of the ambient air.
When choosing the place of installation and while
operating the appliance, make sure that the air
supply is free of chemical substances containing
fluorine, chlorine, sulphur etc. Sprays, solvents and
cleaning agents, paints, adhesives etc. contain the
kind of substances that can lead to corrosion even in
the exhaust system when the appliance is operated
depending on the ambient air in the worst case
scenario. Particularly in hair-cutting salons, lacquering
and finishing, cleaning facilities, the appliance must be
operated independent of the ambient air! Otherwise,
a separate installation room is required to guarantee
that the air supply is free of the above mentioned
substances.
