INSTRUCTIONS FOR STARTING AND STOPPING
The ignition and switch off operations are carried out via command sequences using the con-
trols on the control panel which is at the lower front of the water heater.
During initial installation we suggest you check that:
• The water heater is correctly connected to the water system (supply, distribution and drai-
nage), checking that the "TECHNICAL DATA" according to paragraph 3 are respected,
• The water tank is completely full,
• The heater is connected to the electric supply at 230V,
• The water heater is connected to a fl ue gas exhaust system as foreseen in paragraphs 4.5
and 5,
• The "FLUEGAS PROTECTOR" has been correctly connected, as illustrated in paragraph 5,
• The room aeration has been checked where the heater is installed, also for compliance with
the applicable national and local regulations.
IGNITION
The operations shall be as follows:
• Open the gas valve,
• Press the switch 4. in the "I" position (fi gu-
re 15) so that the incorporated signal lamp
lights,
• Set the thermostat knob 1. (fi gure 15) to the
chosen position (I, II, III, E or MAX) from ap-
proximately 40°C to 72°C,
• Check for ignition (automatic) through the
signal lamp 2. (fi gure 15).
If the water heater does not ignite, it will
lock out automatically, signalling this via
the red signal lamp 3. (fi gure 15).
• We suggest you repeat the operation at
least twice, after which, if the heater does
not start, call in a qualifi ed maintenance
technician.
NORMAL OPERATION
During heating it will be necessary to adjust the thermostat knob 1. (fi gure 15) to the required
temperature, to be chosen between the values of minimum 40°C and maximum 72°C.
We suggest you set the thermostat at an intermediate position, sectors II or III (maximum 60°C)
in order to reduce the formation of scale deposits inside the water heater.
IMPORTANT NOTE: we suggest you increase the temperature of the water he-
ater to the maximum value (thermostat knob set to MAX) at least every two
weeks, for approximately six hours. This reduces the risk of proliferation of Le-
gionella bacteria, dangerous for health, in the water.

RESET
IMPORTANT: at fi rst start-up, due to the
possible presence of air in the gas pipes,
it is likely that the burner will not ignite; in
this case, repeat the start-up sequence a
number of times as already suggested.
