WATER HEATER INSTALLA-
TION
1.1 INSTALLATION RECOMMENDA-
TIONS.
The Julius water heater has been designed for wall
installation. It must be used for the production
of domestic hot water and similar purposes.
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).
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.
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 inside or between
cabinets, ensure sufficient space for normal ser-
vicing; 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 ad-
equate 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:
“Julius” water heaters cannot be installed:
- in bedrooms or bathrooms;
- in areas with a risk of fire (for example: garages)
- this provision also applies for flue ducts;
- on the vertical projection of hobs;
- in places/environments that constitute com-
mon parts of office condominiums such as
stairs, cellars, entrance halls, attics, lofts, escape
routes, etc. if they are not located inside techni-
cal 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).
Moreover, open chamber water heaters must
not be installed in places where commercial,
artisan or industrial activities take place, which
use products that may develop volatile vapours
or substances (e.g. acid vapours, glues, paints,
solvents, combustibles, etc.), as well as dusts (e.g.
dust deriving from the working of wood, coal
fines, cement, etc.). These may be damaging for
the components of the appliance and jeopardise
functioning.
It is also appropriate that they are not installed in
places where wood-burning heat generators are
present (open fires), which are not sealed with
respect to the installation environment.
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.
They must also be installed in an environment
in which the temperature cannot fall below 0°C.
They must not be exposed to atmospheric agents.
