Siphon overflow drain
The boiler’s siphon is equipped with a supplementary safety discharge
SCD
that protects the burner in the very situation in which the condense does
not from correctly from the drain pipe downstream from the siphon. Since
this is easily accessible from the rear of the boiler, evaluate the opportunity
to use it or not before installing the boiler, by connecting to it a section of
flexible hose 1 suitable for condense. On its other end, the hose 1 should be
inserted, avoiding bends and kinks, in a suitable drain, such as the funnel of
the condense drain or safety valve. Do not pierce the prepared hole 4 .
As an alternative, although NOT recommended, you could simply leave the
drain SCD open. The burner will anyway be protected if the siphon gets ac-
cidentally blocked, but the condense (acid) will leak into the environment
and could damage surfaces it touches (such as marble).
Check the seal of siphon, making sure that the caps
2, 3, 5 and 6
are
properly and completely screwed/inserted.
Positioning and fastening
Remark:
A re-usable metal jig (
D
in the figure) can be
ordered separately, so as to facilitate connections
and fixing points positioning (when the original
connection kit is used).
If the metal jig and/or the
original connection kit are not used, refer to the
paragraph "Dimensions and connections" on page
18 for the position of the connections directly on
the boiler.
f
Locate the exact position of the boiler considering the
sufficient clearances for maintenance and servicing,
especially 280mm on the right side to allow the open-
ing of the connection door.
f
If the metal jig is used, fix it on the wall caring to po -
sition the upper side at 2005mm...2020mm from the
floor (boiler's support pads can be adjusted within
these limits * ). Holes B can be eventually used to fix
the jig by means of screw anchors.
f
Fix up the connections and all ducts for heating flow
and return, storage coil flow and return, cold water,
gas, flow/return to solar collectors and electrical ca -
bles, predisposing them in the holes of the metal jig or
respecting the measures in the paragraph "Dimensions
and connections" on page 18.
f Remove the jig.
Remove, from the boiler, all the plastic caps
placed to close the hydraulic connections.
