Calibration gas valve
Before calibration check the mains pressure: 20 mbar for
Natural gas - 37 mbar for LPG.
After each replacement of the electronic board or gas valve,
set the appliance (complete electronic calibration
The calibration of gas valve cancels the values (min/max)
set at the factory.
The view, by means of a pressure gauge connected to
the gas valve, of the pressure values (min/max) set at the
factory, is carried out through the Manual Calibration (see
chapter Service Menu).

Preliminary checks
Check that:
- The data of the power supply networks corresponds to that stat-
ed on the data plate
- The data plate information corresponds to that of the power
supply networks (electric, water, gas)
- The installation complies with the local regulations in force
- The electrical connection to the mains and of the earthing con-
nection have been performed correctly.
Appliance start-up
Following the necessary checks, proceed with the following op-
erations:
Electrically power the water heater
Open the gas valve installed upstream of the water heater
Open the water tap at the bottom of the water heater
- Press the power button
- The display shows:
1. Software review

Water temperature adjustment
The water temperature can be set between 37 and 60°C.
- Use
and
to increase and decrease the water temperature,
the symbol
flashing for 5 seconds and the display shows
the new temperature.
Contact with hot water at a temperatu-
re ≥50 ° C can cause severe burns.
For daily use of the appliance it is re-
commended to set the temperature at
a value not exceeding 50°C.
The appliance is set to maintain a constant water tempe-
rature. It could happen that in the case of withdrawals at
extremely low flow rates, the water temperature rises abo-
ve the set value, causing burns. It is advisable to check
always the water temperature before any use.
Set point regulation
To reduce gas consumption and prevent limescale in the heat
exchanger, it is recommended to set the appliance at the mini-
mum temperature most suitable for the domestic use.
Recommended temperature setting:
Kitchen
50°C - 55°C
A cause of the system and environmental conditions could be a
discrepancy between the temperature set on the appliance and
that actually supplied to the user.
