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.
Outdoor installation in a partially protected place
“City Max xx K”
forced draught, condensing mod
-
els can be installed outdoor, but only in partially
protected places.
The boiler minimum and maximum working tem
-
peratures are mentioned in the paragraph "Tech-
nical data" on page 45 and on the boiler data plate.
The materials used
for the boiler installation, in-
cluding the devices and/or the materials used for
thermal insulation, should be so to
maintain their
functionality within the temperature range indi
-
cated on the data plate.
If the place
where the boiler is located is converted
from outdoor to indoor
(e.g. veranda) it will
be necessary to
verify the compliance
of the new configuration with the laws and rules in force,
and to make the modifications required.
Positioning and fastening
Remark: A re-usable metal jig (
D
in the figure) can be ordered separately, so as to facilitate connec
-
tions 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 connec-
tions" on page 14 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: at least 50mm laterally and 300 mm on the lower side
f
To fix the boiler with wallplugs (“stud” type with nut), centre the relevant wall holes as regards
to
A
points. To hang it with open hooks, place hooks in correspondence with
B
points.
