2. OPERATING INSTRUCTIONS
2.1 Introduction
SUPREME E
is a high efficiency, instantaneous domestic hot water heater using
natural gas or propane gas, equipped with an atmospheric burner with electronic
switch, airtight chamber and forced ventilation. For interior or partially protected
exterior installation (in accordance with EN 297/A6) with temperatures no lower
than -5ºC.

Symbol flashing: the burner is on.
If the burner is off, this symbol is not displayed.

Stationary symbol. Pressure switch open. Heater switched off (fault)
Rotating symbol. Heater working, normal operation.
During a DHW demand (generated by drawing domestic hot water), the display
shows the actual DHW outlet temperature.
2.3 Lighting and turning off
Preliminary operations and checks
1.
Make sure the hot water taps are closed.
2.
Open the water heater gas supply cock, located on its gas connection.
3.
Check that it is connected to the network.
Lighting
Turn the knob to the required water heating level.
fig. 2 Lighting
The unit will immediately be ready to operate whenever hot water is drawn.
Turning off
The burner goes off automatically when the hot water demand
ceases.
No special operation is needed in order to carry out another lighting phase. To
completely shut down the unit, turn the knob to position
.
fig. 3 Unit deactivated
In case of prolonged shutdown close the gas cock ahead of the unit.
For long periods of inactivity during the winter months, to avoid frost damage it is
advisable to drain all the water from the water heater.
2.4 Adjustments
Manual setting of burner power
Use the power adjustment knob (ref. 3 - fig. 1) to select the water heater power,
minimum or maximum and intermediate positions depending on the required water
heating level. Turn the knob anticlockwise and the unit heats the water at maximum
power. If the temperature is too high, for example in the summer, or when a reduced
flow of not very hot water is necessary, turn the knob clockwise. This reduces the power
(and gas consumption). In the position
the unit is deactivated.
Temperature setting
The water temperature can be easily set with the temperature selector: turn it to the
right to increase the temperature, or to the left to decrease.
fig. 4 Temperature adjustment
Faults
After making the adjustments described above, the water heater is ready to operate in
completely automatic mode. When a hot water tap is opened, an intermittent discharge
is generated on the ignition electrode, which causes lighting of the burner and, at the
same time, operates the gas extraction fan.
All the electronic models have an ionisation electrode inserted in the burner to control
correct flame presence. In case of malfunction or no gas with subsequent burner shut-
down, close the hot water tap.
It is then necessary to eliminate the cause or the element preventing the gas from
reaching the water heater, e.g. inadvertent closing of the gas cock, empty gas cylinder,
etc.
Water heater shutdown status is deactivated by closing and opening the hot water tap.
Repeat the operation if the delivery of hot water is not restored after eliminating the
cause
and opening the hot water tap. If the fault persists, contact the After-Sales Technical
Service.
