2
Loosen the screw cap “

” 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
Tighten the screw cap “
D
” inside the connection point
of the pressure gauge.
