BOILER INSTALLATION - MINIMUM DISTANCES FOR FIXING TO WALL
To allow access inside the
boiler for maintenance
operations, the minimum
distances shown in fig. 2
must be kept.
To aid installation, the
boiler is supplied with a
template (see fig. 1) for
advance location of
connections to pipes. In
this way, you may simply
hook up the boiler when
the wall fixings are
completed (fig.1).
To install the boiler
proceed as follows (see
fig.2):
1. Use a spirit level
(min. 25mm in length)
to draw a line on the
wall where the boiler
is to be installed.
2. Position the top of the
template on the line
drawn with the spirit level, keeping to the recommended distances;
now mark the two points where the two fixing screws or brackets
are to go, then mark the points where the water and gas
connections will go;
3. Take away the template and proceed by connecting up the
connectors supplied with the boiler to the hot and cold water
supplies, gas system and heating pipes;
4. Mount the boiler on the wall using the fixing screws or brackets and
make all necessary pipe connections.
WATER CONNECTIONS
To facilitate installation, the boiler is equipped with a fittings kit (fig. 3).
IMPORTANT:
Before connecting the heating system pipes, carefully clean the system to prevent
residual dirt from entering into circulation and negatively affecting boiler function.
Install a funnel with discharge under the safety valve (calibrated to 3 bar) to
collect water in case of leaking due to overpressure. No safety valve is needed for
the domestic hot water circuit, but if the cold main inlet pressure exceeds 5 bar a
pressure reducing value should be fitted.
ADVICE AND SUGGESTIONS FOR DEALING WITH VIBRATIONS AND NOISE
FROM THE SYSTEM
avoid using pipelines of reduced diameter;
avoid the use of tight bends and adapters in important sections;
clean out the system thoroughly before connecting up the boiler in order to
eliminate any residue left in the pipes and radiators.
N.B.: Make sure that the water and heating pipes are not used as earth connections for electrical apparatus.
They are in no way suitable for such purposes
