Installation site

This boiler is not suitable for outdoor installation. This boiler
may be installed in any room. However if the boiler is being
installed in a room containing a bath or shower it must only
be installed in zones 2 or 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.
If the boiler is to be installed in a timber frame building it
should be fitted in accordance with the current version of the
Institute of Gas Engineers document IGE/UP/7. If in doubt
seek advice from local gas undertaking or the manufacturer.

Minimum clearances

C C
A 165 mm: Air/flue pipe, 60/100 mm diameter
275 mm: Air/flue pipe, 80/125 mm diameter
B 180 mm; optimum approx. 250 mm
C 5 mm; optimum approx. 50 mm
D 500 mm in front of the heat generator to enable
easy access for maintenance work (may be
provided by an opening door).
It is not necessary to maintain a clearance between the
product and components made of combustible materials that
go beyond the minimum clearances.
6.5

Compartment Ventilation

The boilers are very high efficiency appliances.
As a consequence the heat loss from the appliance casing
during operation is very low.
Compartment ventilation is not required as the products are
only certified, and can only be fitted with a concentric flue
system.

Air/flue pipe

6.6.1 Regulation
Different flue outlet configurations can be carried out.
–
Consult the installation manual for air/flue gas systems
for more information about the other possibilities and
associated accessories.
Minimum fall
44 mm/m
–
Standard flue terminal kits have an in-built fall back to
the boiler to drain the condensate. These can be fitted
level between the appliance and the termination position.
All other extended flues must have a fall of at least 44
mm/m.
The maximum length of the flue outlet is defined according to
its type (for example C13).
–
Whatever the kind of flue system chosen, observe the
minimum distances to position the flue terminals.
–
To install the flue, refer to the separate flue instruction
supplied with your appliance.
–
Explain these requirements to the user of the appliance.
In GB the minimum acceptable siting dimensions for the
terminal from obstructions, other terminals and ventilation
openings are shown in diagram overleaf.
In IE the minimum distances for flue terminal positioning
must be those detailed in I.S. 813 "Domestic Gas Installa-
tions".
The terminal must be exposed to the external air, allowing
free passage of air across it at all times.
Being a condensing boiler some pluming may occur from
the flue outlet. This should be taken into consideration when
selecting the position for the terminal.
