2.2.3 - ASSEMBLING THE BOILER
Before connecting the boiler to the D.H.W.
and heating system pipes, carefully clean
the pipes to remove all traces of metal
resulting from processing and welding
operations as well as any oil and grease
which could damage the boiler or
jeopardize its operation.
Unical
refuses all liability for injury to persons
and animals or damage to property resulting
from non-observance of the above.To install
the boiler:
- Fix with tape the paper template to the
wall
- make two Ø 12 holes in the wall and
insert the hooks;
- position the junction points for the
connection of the gas supply pipe, cold
water supply pipe, D.H.W. outlet, CH flow
and return in the positions shown by the
template.
- fit the boiler onto the support hooks;
- connect the boiler to the gas pipe,
domestic cold and hot water pipes, CH
flow and return pipes.
- connect to electrical supply.

MOUNTING TEMPLATE
2.2.2 - POSITIONING OF THE BOILER
Every boiler is supplied with a dedicated
"Metallic mounting jig" to allow the correct
positioning of the gas, water and C.H.
system connections
when the hydraulic
system is being laid out and before the boiler
is installed.
This mounting jig must be fixed to the wall
chosen for the installation of the boiler
using
two screws with expanding dowels.
The lower part of the mounting jig allows the
correct marking on the wall of the points
where the fittings for the gas, C.H. flow and
return, D.H.W. and D.C.W. have to arrive.
Determine the position of the boiler taking
care:
-
of leaving a minimum clearance of 50
mm on both sides of the boiler to allow
accessibility for service.
-
of a good resistance of the screws
supporting the boiler on the wall.
-
of avoiding to position the boiler above
an equipment whose use could be
prejudicial for the boiler (stove with
emission of greasy vapours, washing
machines, etc...).
IMPORTANT:
350 mm free space must be left between
the top of the boiler and the ceiling to
allow replacement of the magnesium
anode. This condition is met when there
is a space of 436 mm between the axis of
the holes in the boiler bracket and the
ceiling.
The mounting jig allows the completion of all
the connections and the making of the
soundness test of the full installation without
the boiler in place.
If the boiler is not put in place immediately,
protect the different connections in order to
avoid that the mortar and the paint
cannot compromise the soundness of the
subsequent connections.
Because the temperature of the wall, on
which the boiler is fitted, does not rise more
than 60 K when the boiler is in operation,
there are no special requirements to comply
with.
