4. OPERATION WITH SUPPLY GAS IDENTICAL TO THAT AVAILABLE

Check whether the indications on the data plate correspond to the gas distributed. Also check correspondence to the
indications below.
4.1 Checking the supply pressure (Fig. 2)
The supply pressure can be measured by means of a pressure gauge with a
U-shaped pipe, or of the electronic type with a minimum grading of 0.1
mbar.
Unscrew the screw "A" from the pressure tap "B".
-
- Position the pressure gauge.
Switch on the appliance and check that the pressure is the one
-
intended: otherwise check on the cause.
At the end of the operation, reassemble the appliance and check on the
-
connection.
