6.1
Important
▶ Before installation, consult the gas company and current
legislation regarding gas appliance and site ventilation.
▶ Install a gas shut-off tap as close to the appliance as
possible.
▶ After connection to the gas main, the appliance should be
carefully cleaned and tested for leaks; To avoid damage
from excess pressure in the automatic gas regulator, this
should be carried out with the gas valve shut.
▶ Ensure that the appliance installed is suitable for the type
of gas provided.
▶ Ensure that the flow and pressures for the regulator
installed are those indicated for the consumption of the
appliance (see technical data in table 5).
6.2
Selection of location for installation
Considerations relevant to location
▶ Fulfil requirements specific to each country.
▶ The heater must not installed above a source of heat.
▶ Respect the minimum installation measurements indicated
in Fig. 13.
DANGER:
Explosion
▶ Always turn off the gas cock before
carrying out any work on components
which carry gas.
Installation, electrical connection, gas
installation, connection of inlet and exhaust
pipes and initial startup must be realized
exclusively by authorized personnel.
The heater can only be used in the countries
indicated on the appliance type plate.
CAUTION:
Assure that inlet water into the
appliance does not exceed 60 °C, for
example when used as a backup for solar
installations.
▶ A 3-way valve or thermostatic valve
(adjusted to values lower than 60 °C)
must be installed before the appliance if
inlet water temperature exceeds this
limit.
▶ Assure that the installation contains an
expansion vessel.
For outlet temperature greater then 45 °C we
recommend the use of a descaling system.
