MINIMUM DISTANCES FOR
FIXING TO WALL
To allow access in the boiler
for maintenance operations, the
minimum distances shown
below must be respected (fig.
1):
To facilitate installation, the boiler
is supplied with a template for
advance location of connections to
pipes. In this way, you may simply
hook up the boiler when wall work
is completed (fig.2).
Installation Instruction
1) With a spirit level, draw a line
on the wall on which the
boiler will be installed (fig. 1).
2) Position the top of the
template on the line drawn
with the spirit level
(respecting the distances –
see fig. 2) than mark the three
points for insertion of the 3
screw anchors or wall
anchors for fixing the boiler
hanging bracket. (choose
proper anchors according to
the wall type).
3) Fix the hanging bracket.
4) Make connections to the hot
and cold water supply, to the
gas pipe and to the heating
system with the fittings
supplied with the boiler.
Connect pipes and valves as
shown in the picture
5) Position the boiler paying
attention to hang it to the
hanging bracket and make final connections.
WATER CONNECTIONS
To facilitate installation, the boiler is equipped with a fittings kit (see 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 water circuit, but be sure that pressure
does not exceed 6 bar.
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.
WARNINGS
Boilers can be installed externally, in a partially protected place (balcony – see fig. 4) in conformity with local Building Regulation and if the
outside minimum temperature is not lower than –10°C. The manufacturer is not responsible for external installations where the outside
temperature is lower than – 10°C or not in conformity with above instructions.
