How do I use my pressure gauge?

Instructions for pressure testing your system with one of our 'G' model regulators:
1. Close all appliance valves.
2. Open cylinder valve, and allow indicated gauge pressure to stabilise.
3. Close cylinder valve, and observe pressure gauge reading for 3 minutes.
4. The pressure gauge reading should remain constant if there is no leak in the system.  

Note: A pressure gauge cannot provide an indication of liquid LPG remaining in the cylinder, only its vapour pressure, which is a constant at any given temperature.

The pressure gauge has a range of 0-10 bar. Campingaz is usually Butane, but sometimes it is a mix of Butane and Propane. Propane is added where Campingaz is used in winter and cooler climates, on occations Campingaz cylinders are filled with solely Propane, hence the range on the gauge.

The information below can be used as a guide to the approximate pressure one might expect at a given temperature.​

The primary use of the gauge is for leakage testing, on the low pressure side.

I.E. from the outlet of the regulator to and including the appliance.

This down stream has a pressure of 30 mbar

So when testing, if you have a very small leak, it will take some time for the gauge to react/decrease, hence the 3 minutes duration of testing. The actual pressure reading is irrelevant, you are only looking for a pressure drop over the 3 minutes.

I leak on the high pressure side, would result in the pressure gauge reading dropping quickly and you would likely smell gas in your cylinder locker.

IF YOU HAVE DISCOVERED OR SUSPECT A LEAK:

1. Shut off the LPG supply at the main supply valve.

2. Extinguish any naked flames and other sources of ignition.

3. Do not operate electric switches.

4. Ventilate the area by mechanical means ONLY

Do not use the installation until it has been inspected/repaired by a "competent person".
