WATER HEATER.
1.1 INSTALLATION
RECOMMENDATIONS.
e Julius Eco 11-14 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. ey
are not designed to be installed on plinths or
oors (Fig. 1-1).
e place of installation of the appliance and
relative Immergas 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 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.
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 appliances
removed from other systems. e 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.
Installation of the Julius Eco 11-14 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 systems powered with the
above-mentioned gas in rooms where the oor
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 it is advisable to leave clearance of at least 50 cm between the water heater
casing and the vertical sides of the cabinet (Ref.
Fig. 1-1A). Leave adequate space above the
water heater for possible water and ue removal
connections.
Do not rest objects on the appliance.
Keep all ammable objects away from the appliance (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 ttings. 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 o and contact an
authorised company (e.g. the Authorised Technical Assistance centre, which has specically
trained sta 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:
- these water heaters cannot be installed in
bedrooms, studio ats and bathrooms. ey
also cannot be installed in rooms with wood
(or solid fuel) burning heat generators and in
communicating rooms.
- Installation in places with a re risk is prohibited (for example: underground car parks,
garages), potentially dangerous places, gas
appliances and relative ue ducts.
- 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. oor landings, entrance halls, etc.).
- Installation is also forbidden in places/rooms
that constitute public areas of apartment
buildings such as cellars, entrance halls, attics, los, 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).
- Type B 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 nes, cement, etc.).
ese may be damaging for the components
of the appliance and jeopardise functioning.
- ey must also be installed in an environment in which the temperature cannot fall
below 0°C. They must not be exposed to
atmospheric agents.
YES NO
Attention: wall mounting of the water heater
must guarantee stable and ecient support for
the generator.
e dowels, which come as standard, can 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.
ese appliances are used to heat water to below
boiling temperature in atmospheric pressure.
ey must be connected to a DHW distribution
network suited to their performance and power.

1.3 GAS CONNECTION.
Our water heaters are designed to operate with
methane gas (G20) and LPG. Supply pipes must
be the same as or larger than the 1/2”G water
heater tting. Before connecting the gas line,
carefully clean inside all the fuel feed system
pipes to remove any residue that could impair
water heater eciency. Also make sure the gas
corresponds to that for which the water heater
is prepared (see water heater data-plate). If different, the water heater must be converted for
operation with the other type of gas (see converting appliance for other gas types). It is also
important to check the dynamic pressure of the
mains (methane or LPG) used to supply the water
heater, which must comply with EN437 and its
attachment, as insucient levels may reduce generator output and cause discomfort to the user.
Key:
AC - Domestic hot water outlet
AF - Domestic cold water inlet
G - Gas supply
A type-approved and certied gas cut-o cock
must be inserted on the gas pipe before connection to the appliance.
Ensure correct gas cock connection, by inserting
a at gasket. e gas supply pipe must be suitably
dimensioned according to current regulations
in order to guarantee correct gas ow rate to the
burner even in conditions of maximum generator output and to guarantee appliance eciency
(technical specications). e coupling system
must conform to standards in force (EN 1775).

Fuel gas quality. e appliance was designed
to operate with combustible gas free of impurities; otherwise it is advisable to t special lters
upstream of the appliance to restore the purity
of the fuel.
Storage tanks (in case of supply from LPG depot).
- New LPG storage tanks may contain residual inert
gases (nitrogen) that degrade the mixture delivered
to the appliance casing functioning anomalies.
- Due to the composition of the LPG mixture, layering of the mixture components may occur during
the period of storage in the tanks. is can cause
a variation in the caloric value of the mixture
delivered to the appliance, with subsequent change
in its performance.
