Managing Your LPG Cylinders

I have no gas?

If your home’s LPG appliances are not working, please check that the gas has been turned on and that there is gas in the cylinders

How long will my LPG cylinder last?

1kg of propane = 50 megajoules

Cylinder size in KG's Energy Rating in MJ
8.5 425
13.5 675
45 2250
210 10500

Therefore, if an appliance uses 150mj, if its connected to a 45kg cylinder (which equates to 2250mj) to calculate the number of hours your cylinder will last would be: 2250mj / 150mj = 15 hours continuous use.

How to check how much gas is left in an LP gas cylinder

To get an approximate level of the gas left in your LPG cylinder, pour boiling water over the cylinder, starting from the top and working your way down the side to the base.

Next, run your hand down the gas cylinder starting from the top. The hot water will heat the metal of the cylinder but due to the cold nature of LPG, the metal will remain cool wherever it is in contact with the LPG. Therefore, the section of cylinder that remains cool is the section that contains product.

Please note: Only adults should handle boiling water. Supagas is not responsible for any mishandling of the boiling water.

Opening the Valve on Your Gas Cylinder

Ensure that the valve on the 45kg LPG cylinder is turned open in the direction of the arrows. It is recommended that you only draw gas from one cylinder at a time to avoid running out of gas. This can be done by ensuring you only have one cylinder valve turned open at a time.

On a manual regulator

Ensure that the valve (pictured in red) on the regulator is turned towards the cylinder that contains gas. ensure that the changeover valve is turned completely towards the cylinder it is drawing from.

On an automatic Regulator

Both cylinder valves are turned on with the auto regulator as opposed to one at a time with the manual regulator. Check with the manufacturer’s operating instructions as to how your automatic regulator works, as different manufacturers have different methods of operation.

Turning on your LPG hot water System

If your cylinders have gas in them, and the cylinders have been turned on as per the above instructions, but you still do not have any hot water, please ensure that your hot water system has been turned on as per the manufacturer’s instructions. This may require you to restart the hot water system by switching it off at the plug and switching it on after 10 seconds.
