4 Assembly

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!
h
Danger of death by electric shock! If a room
sealed boiler is installed in a room with a bath
or a shower, the electrical switches and the
boiler controller, which operate at mains volt-
age must be mounted in locations where any
person in the bath or in the shower cannot
reach them
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.)
Further details concerning the fundamental characteristics
when modifying existing cabinets or enclosures, including
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 accordance with
the Institute of Gas Engineers Publication "IGE/UP/7
Edition 2 Gas installation in timber framed and light steel
framed buildings". Please note the following instructions
before choosing where to
install the heater:

Caution!
Do not install the appliance in rooms prone to
frost. In rooms with aggressive steam or dust,
the appliance must be operated independently
of the ventilation!
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.
10
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.

Fig. 4.3 Required minimum gaps/assembly clearances
The boiler must be mounted on a flat, vertical wall sur-
face which is large enough for the boiler including the
required minimum space requirement and the space re-
quired for assembly (Fig. 4.3). These are shown on the
mounting template supplied with the boiler, and are:
– 5 mm on each side of the boiler
– 145 mm underneath the boiler
– 165 mm* above the boiler if using a flue pipe of 100
mm outside diameter
– 246 mm* above the boiler if using a flue pipe of 125
mm outside diameter
– 500 mm** in front of the boiler

Note!
If the boiler is to be installed in a timber framed
building, it should be fitted in accordance with
"IGE/UP/7 Edition 2 Gas installations in timber
framed and light steel framed buildings".
It is not necessary to maintain a clearance between the
appliance and combustible materials or components,
since, at the rated heating power of the appliance, the
temperature here is always lower than the permitted
temperature of 85 °C.
