4.5 Starting up the water heater
Once the system has been filled,
proceed as follows:
• Check that the exhaust flue is free
of obstructions and correctly
connected to the water heater;
• Switch on the power supply to the
water heater;
• Open the gas isolation valve;
• Place switch 1 in the ON position
(see 2.7 “Control Panel”), after a few
seconds the circulating pump will start
to run;
• Use button 6 to set the SUMMER,
WINTER or SUMMER/WINTER
function. The symbols
will light
up (fixed light) to indicate that the
water heater is working;
• The automatic ignition system will then
light the burner. This operation is
repeated for 3 times. It may however
be necessary to repeat the operation in
order to eliminate all the air from the
pipes. To repeat the operation, wait
approximately three minutes before re-
attempting to light the water heater. To
reset the water heater Switch off
switch 1 (see 2.7 “Control Panel”) and
switch it back on again and repeat the
lighting procedure;
• With the water heater ignited, if the
system still emits noises, the
operations must be repeated until all
the air has been removed;
• Check the pressure in the system. If
the pressure has fallen, re-open the
filling tap until the code H2O
disappears on the display and the
pressure reaches the middle of the
green area (1,2 bar). On completion,
close the filling tap.
• If the CO2 value does not correspond to the specified value, adjust screw V (see fig. 1) on the venturi clockwise
to reduce the CO2 value or anticlockwise to increase it
