1.1 INSTALLATION RECOMMENDATIONS.
ATTENTION:
operators who install and service the
appliance must wear the personal
protective equipment required by ap-
plicable law.
e Victrix EXA boiler has been designed for wall
mounted installation only, to heat and produce domes-
tic hot water for domestic use and similar purposes
(when the boiler is connected to an external storage
tank unit).
e place of installation of the appliance and relative Immer-
gas accessories must have suitable features (technical and
structural), such as to allow for (always in safe, ecient and
comfortable conditions):
-
installation (according to the provisions of technical legisla-
tion and technical regulations);
-
maintenance operations (including scheduled, periodic,
routine, special);
-
removal (to outdoors in the place for loading and transport-
ing the appliances and components) as well as the eventual
replacement of those with appliances and/or equivalent
components.
e wall surface must be smooth, without any protrusions or
recesses enabling access to the rear part. ey are not designed
to be installed on plinths or oors (Fig. 1).
By varying the type of installation the classication of the boiler
also varies, precisely:
-
Type B
23
or B
53
boiler if installed using the relevant terminal
for air intake directly from the room in which the boiler has
been installed.
-
Type C boiler if installed using concentric pipes or other types
of pipes envisioned for the sealed chamber boiler for intake
of air and expulsion of ue gas.
Only professionally enabled companies are authorised to install
Immergas gas appliances.
Installation must be carried out according to regulation stand-
ards, current legislation and in compliance with local technical
regulations and the required technical procedure.
ATTENTION:
it is not permitted to install boilers that
are removed and decommissioned from
other systems. e manufacturer declines all li-
ability for damages caused by boilers removed
from other systems or for any non-conformi-
ties of such equipment.
ATTENTION:
check the environmental operating
conditions of all parts relevant to in-
stallation, referring to the values shown in the
technical data table in this booklet.
ATTENTION:
installation of the Victrix EXA boiler
when powered by LPG must comply
with the rules regarding gases with a greater
density than air (remember, as an example,
that it is prohibited to install plants powered
with the above-mentioned gas in rooms where
the oor is at a lower quota than the country
level).
ATTENTION:
if installing a kit or servicing the ap-
pliance, always empty the system’s
domestic hot water circuit rst so as not to
compromise the appliance’s electrical safety
(Par. 2.9 and 2.10).
