10.1 Adjustments
The appliance has already been factory set by the manufacturer.
However, should it need to be readjusted, for example after non-sched-
uled maintenance, replacing the gas valve or gas conversion, proceed
as described below.
b
Adjustments to maximum power must be performed in the indi-
cated sequence and only by qualified technicians.
-
Remove the casing by unscrewing the fixing screws

(see sec-
- Loosen the screw of the pressure test point (1) downstream from
the gas valve by roughly two turns, then connect the pressure
gauge
- Disconnect the compensation connector (5) from the gas valve
- Remove the protective hood (2)
-
Open a water tap to its maximum flow rate, set the temperature
selector to maximum and power up the water heater
