• Installation standards: these boilers are designed
exclusively for wall-mounted installation; they must
be used for room heating and the production of
domestic hot water for household and similar uses.
The wall surface must be smooth, i.e. without any
protrusions or cavities enabling access to the back
part. They are NOT designed for installation on
plinths or floors (see figure).
Caution: installation of the boiler on the wall must
guarantee a stable and efficient support for the gen-
erator. The plugs supplied with the appliance ensure
adequate support only if inserted correctly (accord-
ing to technical standards) in walls comprising bricks
or breeze blocks, partitions with limited static proper-
ties, or other provided that a static test is performed
to ensure adequate support.
These boilers are used to heat water to below boiling
temperature in atmospheric pressure.
The appliance must be connected to a heating cir-
cuit and domestic water distribution circuit in corre-
spondence to performance and power specifications.
It must also be installed in an ambient temperature
that does not fall below 0°C, and must not be ex-
posed to atmospheric agents.

INSTALLATION
1.1 Warnings.
Immergas gas appliances must be installed exclu-
sively by a professionally qualified and authorised
technician.
Installation must be performed in compliance with
standards UNI and CEI, current legislation and in
observance with local technical standards accord-
ing to a professional code of practice.
The following standards must be observed in par-
ticular: UNI-CIG 7129 and 7131 and CEI 64-8 and
64-9.
Before installing the appliance, ensure that it is de-
livered in perfect condition; if in doubt, contact the
supplier immediately. Packaging materials (staples,
nails, plastic bags, expanded polystyrene etc.) con-
stitute a hazard and must be kept out of the reach of
children.
If the appliance must be installed inside or between
other cabinets or items of furniture, ensure that suf-
ficient space is left for maintenance; a clearance of
2÷3 cm between the boiler casing and the sides of
the cabinet is recommended. Keep all flammable
objects well away from the appliance (paper, cloths,
plastic, polystyrene, etc.).
In the event of malfunctions, faults or incorrect op-
eration, switch the appliance off immediately and
contact a qualified technician (e.g. from the Immergas
Service centre to ensure use of original spare parts).
Never attempt to modify or repair the appliance alone.
Failure to observe the above implies personal respon-
sibility and renders the guarantee null and void.
