Installation, gas connection, the air intake pipes/ue gas release
tube installation, electrical connection and commissioning of the
water heater must be entrusted to an authorised installer in ac-
cordance with the Law in force
Verify if the mains gas network corresponds to that indicated for
use of the appliance
Install a valve on the gas supply line, upstream of the appliance,
in a visible and accessible position and in any case as close as
possible to the appliance
Verify that the appliance to be installed is tted for the gas type
distributed over the network
Check the water hardness (°dH).
If is very hard, t, upstream from the appliance, a device for
softening water or another comparable mechanism that com-
plieswith the applicable regulations
Wall mounting
Precautions
Do not install this appliance in a room with an ambient
atmosphere containing fatty and/or corrosive dust or va-
pours
hThe appliance must be installed on a suitable wall and close to a
ue gas release tube
hTo allow maintenance operations, leave the minimum distances
shown in the gure around the appliance.
Location
hIt is forbidden to install the water heater in rooms where the
temperature can drop below 0°C. If the appliance is positioned
in areas exposed to the risk of frost, the water heater must be
disconnected and emptied
hThe water heater must never be hermetically sealed in a cabinet or
in a cavity and there must be an adequate supply of air
hThe water heater must not be placed above a cooker or other
cooking appliance in order to prevent the deposition of cooking
vapour grease and consequent malfunction
hHeat-sensitive walls (e.g. wooden ones) must be protected with
appropriate insulation
Support bracket
Having established the position of the appliance, drill no. 2 Ø 6 holes
to apply the support bracket (use the same bracket to mark the holes).
Secure it with the plugs supplied.
Below is descried the type of rear and horizontal outlet which is the
most common:
hPosition the paper template between the wall and the appliance
support ns
hMark the centre of the hole of the pipe
hDrill a Ø 105 mm hole as indicated on the paper template
hConnect the appliance to the support bracket and connect the ue
gas release tubes.
Electrical connection
Electrical current with 230V voltage
Before any work on the electrical equipment, always dis-
connect the 230V voltage.
Connect the supplied cable to the line respecting the phase, neutral and
earth.
In the event of replacement of the power supply cable, an operation
which must in any case be performed by a qualied technician, connect
the appliance with a cable type H 05 V VF 3 x 0.75 mm2 with Ø max 7mm
similar to that provided. In addition, the earth wire must be 30 mm longer
than the power supply cables. Power the appliance via an all-pole switch
with an opening of at least 3 mm between the contacts. For maintenance
operations, disconnect the power by turning the omni-pole switch.
N.B. no responsibility is accepted for damage to persons, animals or
property caused by failure to earth the appliance and the creation of an
electrical installation that does not comply with current standards (CEI
68.4).
Arrange for qualied personnel to check that the electrical installation is
suitable for the maximum power absorbed by the appliance, as indicated on
the data plate, ensuring in particular that the wire section of the systemis
suitable for the power absorbed by the appliance.
For the main power supply of the appliance from the mains, the use of
adapters, multiple sockets and/or extension cords is not permitted.
The use of any component that uses electricity involves the observance
of a number of fundamental rules such as:
hDo not touch the appliance with wet parts of the body and/or
bare feet
hDo not pull the electrical cables
hDo not leave the appliance exposed to atmospheric agents (rain,
sun, etc.)
hDo not allow the appliance to be used by children or inexperi-
enced persons.
The power cable of the appliance must not be replaced by the user.
If the cable becomes damaged,switch off the appliance and for the purposes
of replacement, use exclusively professionally qualied personnel.
Where the appliance will not be used for a certain period of time, it is
advisable to disconnect the power supply to all the system components
that use electricity.
Gas connection
Non-compliance with theapplicable laws may result in re or
explosions, causing serious damage to materials, animals or per-
sons, possibly even irreparable
Determine the diameter of the pipe in accordance with the regulations
in force.
Before installing the appliance blow into the gas pipe in order to remove
any residue. Connect the water heater to the gas pipe of the internal
system and t upstream from the appliance a valve for gas interception
and opening.
Comply with the prescriptions of the relevant standard.
For initial start-up of the appliance, the following checks must be carried
out by qualied technicians:
hChecking for internal and external leakage of the gas supply system
hAdjustment of the gas ow rate according to the power required
by the appliance
hThat the appliance is powered by the type of gas for which it was
designed
hThat the gas supply pressure is in the range between the values
indicated on the data plate
hThat the gas supply system is dimensioned for the capacity re-
quired by the appliance and is equipped with all the safety and
control devices required by current regulations.
hIn case of absense and if the water heater is not used for a longer
period, close the gas supply to the device.
Do not obstruct the ventilation openings of the room where a gas appliance
is installed in order to avoid dangerous situations such as the formation
of toxic and explosive mixtures.
Do not use the gas pipes as electrical appliance earthing devices.
Water connection
Water at a temperature higher than 50°C causes se-
rious burns. Check the water temperature before any
use.
