WATER HEATER INSTALLA-
TION
1.1 INSTALLATION
RECOMMENDATIONS.
The water heaters have been designed for wall
installation only, for the production of domestic
hot water in domestic and similar uses.
The place of installation of the appliance and
relative Immergas accessories must have suitable
features (technical and structural) such to allow
(always in safety, efficiency and comfortable
conditions):
- installation (according to the provisions of the
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (to outdoors in the place for loading
and transporting the appliances and compo-
nents) as well as their eventual replacement
with appliances and/or equivalent components.
In the case of wall installation the wall surface
must be smooth, without any protrusions or
recesses enabling access to the rear part. They
are not designed to be installed on plinths or
floors (Fig. 1-1).
By varying the type of installation the classifica-
tion of the water heater also varies, precisely:
- Type B water heater if installed using the
22
relevant terminal for air intake directly from
the room in which the water heater has been
installed.
- Type C water heater if installed using concen-
tric pipes or other types of pipes envisioned for
the sealed chamber water heaters for intake of
air and expulsion of fumes.
Note: appliance classification is provided in the
depictions of the various installation solutions
shown on the following pages.
Only professionally enabled companies are
authorised to install Immergas gas appliances.
Installation must be carried out according to
regulation standards, current legislation and in
compliance with local technical regulations and
the required technical procedures.
Before installing the appliance, ensure that it is
delivered in perfect condition; if in doubt, contact
the supplier immediately. Packing materials (sta-
ples, nails, plastic bags, polystyrene foam, etc.)
constitute a hazard and must be kept out of the
reach of children. If the appliance is installed in-
side or between cabinets, ensure sufficient space
for normal servicing; therefore it is advisable to
leave clearance of at least 3 cm between the water
heater casing and the vertical sides of the cabinet.
Leave adequate space above the water heater for
possible water and flue removal connections.
Keep all flammable objects away from the ap-
pliance (paper, rags, plastic, polystyrene, etc.).
It is recommended not to position household
appliances under the water heater because they
could undergo damage in the case of leaks from
the hydraulic fittings. If this is not the case, the
manufacturer cannot be considered liable for
any damage caused to the household appliances.
For the aforementioned reasons, we recommend
not placing furnishings, furniture, etc. under the
water heater.
In the event of malfunctions, faults or incorrect
operation, turn the appliance off and contact an
authorised company (e.g. the Authorised Tech-
nical Assistance centre, which has specifically
trained staff and original spare parts). Do not
attempt to modify or repair the appliance alone.
Failure to comply with the above implies personal
responsibility and invalidates the warranty.
• Installation regulations:
- this water heater can be installed outdoors
in a partially protected area. A partially pro-
tected area is one in which the water heater
is not exposed to the direct action of the
weather (rain, snow, hail, etc.).
N.B.: this type of installation is only possible
when permitted by the laws in force in the ap-
pliance's country of destination.
- Installation in places with a fire risk is pro-
hibited (for example: garages, closed parking
stalls), gas appliances and relative flue ducts,
flue exhaust pipes and combustion air intake
pipes.
- Installation is prohibited on the vertical
projection of cooking hobs.
- Installation is also prohibited in places/en-
vironments that constitute common parts of
office condominiums such as stairs, cellars,
entrance halls, attics, lofts, escape routes,
etc. if they are not located inside technical
compartments under the responsibility of
each individual building and only accessible
to the user (for the features of the technical
compartments, see the technical standards in
force).

YES NO
Attention: wall mounting of the water heater
must guarantee stable and efficient support for
the generator
The plugs (standard supply) are to be used only in
conjunction with the mounting brackets or fixing
template to fix the water heater to the wall; they
only ensure adequate support if inserted correctly
(according to technical standards) in walls made
of solid or semi-hollow brick or block. In the
case of walls made from hollow brick or block,
partitions with limited static properties, or in any
case walls other than those indicated, a static test
must be carried out to ensure adequate support.
N.B.: the hex head screws supplied in the blister
pack are to be used exclusively to fix the relative
mounting bracket to the wall.
These appliances are used to heat water to below
boiling temperature in atmospheric pressure.
They must be connected to a DHW distribution
network suited to their performance and power.
