INSTALLATION

The boiler must be installed in a fixed loca-
tion and only by specialized and qualified per-
son in compliance with all instructions con-
tained in this manual. The boiler should be
installed in accordance with the Gas Safety
Regulations.
2. 1 VENTILATION REQUIREMENTS
Detailled recommendations for air supply
are given in BS5440:2. The following notes
are for general guidance:
– It is not necessary to have a purpose
provided air vent in the room or com-
par tment in which the appliance is
installed.
2.2 FIXING THE WALL
MOUNTING BRACKET
– Mark the position of the two wall mount-
ing bracket fixing holes and the flue/air
duct hole on the appropriate wall(s).
– Drill the top two fixing holes using a 10
mm masonry drill and fit the plastic
plugs provided.
– Cut the hole in the wall for the flue/air
duct. The diameter should not be less
than 100 mm (4 in) and must be hori-
zontal. If the hole is not accessible from
the outside of the building, its minimum
diameter should be sufficient to allow
the insertion of the wall liner (130 mm -
5 1 / 4 in diameter) which will be sealed
with mortar.
– Accurately measure the wall thickness,
and note this dimension for later use.
– Secure the wall mounting bracket in
position using the screws provided.
Ensure that it is the correct way up, as
indicated in fig. 4.
2.3 CONNECTING UP SYSTEM
Before proceeding to connect up the boiler,
you are recommended to flush out the sys-
tem in order to eliminate any foreign bodies
that might be detrimental to the operating
efficiency of the appliance. When making
the hydraulic connections, make sure that
the clearances indicated in fig. 1 are
respected. To facilitate the hydraulic con-
nections the boiler is equipped with a valve
pack code 5184817 complete with instruc-
tions sheet.
A safety valve set at 3 bar is fitted to the
appliance, the discharge pipe provided
should be extended to terminate safely
away from the appliance and where a dis-
charge would not cause damage to per-
sons or property but would be detected.
The pipe should be a minimum of 15 mm Ø
and should be able to withstand boiling
water, any should avoid sharp corners or
upward pipe runs where water may be
retained.
The gas connection must be made using
seamless steel or copper
2
(Mannesmann type), galvanized and with
threaded joints provided with gaskets,
excluding three-piece connections, except
for initial and end connections.
Where the piping has to pass through walls,
a suitable insulating sleeve must be provid-
ed.
When sizing gas piping, from the meter to
the boiler, take into account both the volume
flow rates (consumption) in m
relative density of the gas in question.
The sections of the piping making up the
system must be such as to guarantee a
supply of gas sufficient to cover the maxi-
mum demand, limiting pressure loss
between the gas meter and any apparatus
being used to not greater than 1.0 mbar for
family II gases (natural gas).
An adhesive data badge is sited inside the
front panel; it contains all the technical data
identifying the boiler and the type of gas for
which the boiler is arranged.
2.3. 1 Connection of condensation
water trap
The drip board and its water trap must be
connected to a civil drain through a pipe
with a slope of at least 5 mm per metre to

ensure drainage of condensation water.
The plastic pipes normally used for civil
drains are the only type of pipe which is
appropriate for conveying condensation
to the building's sewer pipes.
2.3.2 Requirements for

The heating system design should be based
on the following information:
a) The available pump head is given in fig. 16.
b) The burner starts when the C.H. flow
reaches 400÷450 l/h. This safety con-
dition is ensured by the flow switch.
c) The appliance is equipped with an inter-
nal by-pass that operates with system
heads (H) greater than 3 m. The maxi-
mum flow through the by-pass is about
300 l/h. If thermostatic radiator valves
are to be installed, at least one radiator
should be without a thermostatic valve
(usually the bathroom radiator).
d) A sealed system must only be filled by a
competent person using one of the
approved methods shown in fig. 4/a.
The system design should incorporate
the connections appropriate to one of
these methods.
