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.
