4.5 Starting up the water heater
Once the system has been filled, proceed as
follows:
•
Check that the exhaust vent 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 clockW - BTU/hrise to reduce the
CO2 value or anticlockW - BTU/hrise to
increase it
