Installation site

The site of erection of the boiler should allow proper
connection of the air/exhaust ducting. In addition, there
should be adequate room for maintenance work and air
circulation around the boiler. The boiler can be installed
in any room, however, in rooms with a bath or a shower,
the special requirements of BS 7671 (IEE Regulations),
the electro-technical stipulations of the Building Stand-
ards (Scotland) Regulations and, in IE, the current issue
of IS 813 and the current ETCI Stipulations must espe-
cially be observed.

Danger!
Risk of death from electric shock when
installing an appliance that is independent
of ambient room air in a room with a bath
or shower!
If electric switches and controls are installed
too close to a bath or shower, there is a risk
of electric shock for the person using the
facility.
> Install electric switches and controls that
are operated via mains voltage out of reach
of the bath or shower.
In the event of installation in unusual locations, special
provisions may have to be made. Detailed instructions
for this can be found in BS 5546 and in BS 6798. The
boiler must be installed on a flat vertical wall which is
adequately robust to carry the weight of the boiler.
It is possible to mount onto a wall made of flammable
material if the regulations of the Local Authority and the
legal building stipulations are fulfilled.
In this case however, the unit would have to be mounted
in a specially made enclosure. (You can also use an
existing cabinet or existing enclosure as long as it can
be modified accordingly to suit the new application.) Fur-
ther details concerning the fundamental characteristics
when modifying existing cabinets or enclosures, includ-
ing the requirements for ventilation, are described in BS
6798. If the boiler is to be installed in a half-timbered
house, the installation must be undertaken in accord-
ance with the Institute of Gas Engineers Publication
"IGE/UP/7 Edition 2 Gas installation in timber framed
and light steel framed buildings". Note the following
instructions before choosing where to install the heater:

Caution!
Possible material damage due to an unsuit-
able installation site!
The appliance may be damaged by frost,
aggressive vapours or dust.
> Do not install the appliance in rooms that
are susceptible to frost.
> Do not operate the unit in rooms with
aggressive vapours or dust unless it is
operated in a way that does not depend on
the room air.
When choosing the place of installation and while oper-
ating the appliance, make sure that the combustion air
is free from chemical substances such as e.g. fluorine,
chlorine, sulphur, ammonia etc. Sprays, solvents and
cleaning agents, paints, adhesives etc. contain these
kinds of substances, which - in the worst case scenario -
can lead to corrosion, even in the exhaust system, dur-
ing ambient air dependent operating of the appliance.
Particularly in hairdessing salons, lacquering and finish-
ing workshops, cleaning facilities, etc., the appliance
must be operated independently of the ambient air. Oth-
erwise, a separate installation room is required to guar-
antee that the combustion air supply is free from the
above substances.
