2.3.4. GAS PRESSURE CONTROL

Turn off the device, disconnect the pressure gauge, replace the screw without forget-
ting to place the washer (Ref.C) and contact the gas supplier to check the pressure in
the network. This may require inserting a pressure regulator before the device.

The feed gas pressure must be measured
at the level of the pressure tap (Fig. 4) -
(Ref. B) after removing the screw (Ref. A).
Connect a gauge to the pressure tap by
means of a flexible tube (for example, a
liquid manometer, with a minimum resolu-
tion of 0.1 mbar) and measure the pressure
at the inlet while the device is operating. If
the pressure value is not within the lower
and upper limits indicated in the table, the
device cannot be installed.
