6.6 - Measurement and adjustment
of gas pressure adjustment
The gas supply pressure must correspond to that stated in
the table in chapter 9 at the end of the manual.
For its verification, proceed as follows:
1.- close the gas isolation valve;
2.- access the components inside the appliance, following
the procedure in paragraph 8.2;
3.- loosen the pressure point “A” (see figure 6.8);
4.- connect to a manometer with resolution of at least 0.1
mbar (1 mmH2O);
5.- open the gas isolation valve;
6.- check that the pressure does not exceed the value given
in the table in chapter 9 under “gas supply maximum
pressure”;
7.- open the domestic hot water tap to maximum;
8.- wait for the temperature of the water heater to stabilise;
9.- check that the pressure does not drop to a lower value
than the “gas supply minimum pressure” given in the
table in table 9. If the supply pressure does not respect
the values described, operate upstream from the
appliance in order to take it back within the minimum and
maximum field;
10.- close the domestic hot water tap;
11.- close the pressure point “A” in figure 6.8;
12.- check for gas leaks an all joints.
ATTENTION !!! Perform the leak test using a soap
and water only. The use of naked flames is prohibited.
