3.3.1 GAS INSTALLATION AND LEAKAGE TEST INSTRUCTION
DANGER:
WARNING:
❖ SAFETY
The pressure gauge is designed to check current pressure in system and can
be used to detect leaks in gas systems with a maximum working pressure of
200 kPa (2 bar). The system is supposed to be checked prior to the first use,
after a period of non-use and every time the gas bottle is changed.
Propane is an explosive gas; therefore smoking and open flames are
absolutely prohibited.
❖ TESTING
With a gauge fitted:
1. Close appliance valve,
2. Open LPG cylinder valve,
3. Allow indicated gauge pressure to stabilize,
4. Close LPG cylinder valve,
5. Observe pressure gauge reading for 3 min, pressure gauge reading
should remain constant if no leak in the LPG system is present.
The gauge does not provide an indication of liquid LPG remaining in the
cylinder, only its vapour pressure, which is a constant at any given
temperature.
WARNING:
Do not use an installation that has leaked until it has been inspected and repaired by a
competent person.
