WATER HEATER
INSTALLATION
1.1 INSTALLATION
RECOMMENDATIONS.
e water heaters have been designed for wall
installation only; they 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
have NOT been designed to be installed on
plinths or oors (Fig. 1-1).
By varying the type of installation the
classification of the water heater also varies,
precisely:
- Water heater type B
22 if installed without the
2 intake caps and with the top cover kit
-
Type C water heater if installed using concentric
pipes or other types of pipes envisioned for the
sealed chamber water heaters for intake of air
and expulsion of ue gases.
Only professionally qualified heating/
plumbing technicians are authorised to install
Immergas gas appliances. Installation must
be carried out according to the standards,
current legislation and in compliance with local
technical regulations and the required technical
procedures. 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 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 that it is 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 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 ue removal connections.
Keep all flammable 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.
In the event of malfunctions, faults or incorrect
operation, turn the appliance o immediately
and contact a qualified technician (e.g. the
Immergas Technical Aer-Sales 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 regulations:
- this water heater can be installed outside in a
partially protected area. A partially protected
location is one in which the water heater
is not exposed to the direct action of the
weather (rain, snow, hail, etc..).
- Installation in places with a fire risk is
prohibited (for example: garages, box), gas
appliances and relative ue ducts, ue exhaust
pipes and combustion air intake pipes.
- Installation is prohibited on the vertical
projection of the cooking surface.
- Installation is also prohibited in places/
environments that constitute common parts
of oce condominiums such as stairs, cellars,
entrance halls, attics, los, 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 Reference Standard).
Important: Wall mounting of the water heater
must guarantee stable and ecient support for

the generator.
e plugs (standard supply) are to be used only in
conjunction with the mounting brackets or xing
template to x 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 x the relative
mounting bracket to the wall.
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.
