INSTALLATION
WATER HEATER.
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 as to al-
low for (always in safe, efficient and comfortable
conditions):
- installation (according to the provisions of
technical legislation and technical regulations);
- maintenance operations (including scheduled,
periodic, routine and special maintenance);
- removal (outdoors in the place for loading and
transporting the appliances and components)
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).
By varying the type of installation the classifi-
cation 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.
Only professionally qualified 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.
Attention: it is forbidden to install water heaters
removed from other systems. The manufacturer
declines all liability in the event of damage caused
by water heaters removed from other systems or
for any non-conformities with such equipment.
Attention: before commissioning the water
heater, if it is operated with LPG, make sure
parameters 2 and 13 on page 20 have been set
correctly.
Installation of the water heater 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 sys-
tems powered with the above-mentioned gas in
rooms where the floor is at a lower quota that the
average external country one). Before installing
the appliance, ensure it has been delivered in
perfect condition; if in doubt, contact the supplier
immediately.
Packing materials (staples, nails, plastic bags,
polystyrene foam, etc.) constitute a hazard and
must be kept out of the reach of children. If the
appliance is installed inside or between cabinets,
ensure sufficient space for normal servicing;
therefore, leave clearance of at least 5 cm between
the water heater casing and the vertical sides of
the cabinet. Leave adequate space above and
below the water heater for possible water and
flue removal connections (Ref. Fig. 2).
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 Standards:
- this water heater was designed and built for
installation inside buildings.
- Installation of gas appliances, flue exhaust
pipes and combustion air intake pipes is
forbidden in places with a fire risk (for ex-
ample: garages, closed parking stalls), and
in potentially dangerous places.
- Installation on the vertical projection of
cooking hobs is forbidden.
- Installation is forbidden in places/rooms
that constitute public areas of apartment
buildings, internal stairways or other escape
routes (e.g. floor landings, entrance halls,
etc.).
- Installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics,
lofts, etc., unless otherwise provided for by
local regulations in force.
- It is forbidden to install the water heater
inside a closed recessed frame (e.g. Omni
Container).
- The appliance was designed to be installed in
indoor and protected places.
- It must also be installed in an environment
in which the temperature cannot fall below
0°C. It must not be exposed to atmospheric
agents.
If the water heater is installed in a place whose
temperature drops below 0°C, it is compulsory
to use the antifreeze accessory that provides for
adequate protection down to -15°C.
5
YES
NO
- It is prohibited to obstruct the air intake
and aeration grids where the appliance is
installed.
Attention: wall mounting of the water heater
must guarantee stable and efficient support for
the generator.
The fastening plugs (standard supply) are only to
be used 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 mount.
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.
