Leak test
Prior to checking the connection pressure, all connection points both outside and inside the
appliance must be checked for leaks according to the technical regulations governing gas installations
(TRGI) (using a gas detector or leak spray).
Checking the connection pressure
➢
Close the on site gas valve.
➢
Disconnect the unit from the power supply
(remove fuses or pull the connection-plug)
➢
Unscrew the two screws which are located
down on the left to remove the left side
panel.
➢
Unscrew the sealing screw from the
pressure measurement connection on the
gas valve
„IN“ and connect a manometer.
The manometer used should be accurate to
at least 0.1 mbar.
➢

power supply.
➢
Start-up the appliance.
➢
Measure the connection pressure and
