A
A
2
Loosen the screw cap “A” inside the pressure
inlet.
3
Connect a pressure gauge (not supplied) to the
pressure inlet.
4 Measure the supply pressure with the burner off.
5
Open the gas valve and read the pressure at the
pressure gauge.
6
Close the gas valve and check that the pressure
at the pressure gauge does not drop.
7
Leave the piping pressurised for 10 minutes and
check again that the pressure at the pressure
gauge has not dropped.
If the pressure drops, this is an indication of a gas
leak.
8
If the pressure has remained stable, open the gas
valve again.
9
Disconnect the pressure gauge from the
connection point.
10
Screw the screw cap “A” located inside the
connection point of the pressure gauge.
The gas supply counter must possess the following minimum requirements:
