4.5kg Butane Gas Cylinder

All Flogas butane cylinders have either a 20mm or 21mm valve, so they need be fitted with the correct clip-on regulator. You can double check the size of the regulator by looking on the inside of the regulator.

Different heaters are supplied with different types of regulators, so refer to the heaters instructions if you are using a different regulator.

Make sure the hose coming from the heater is correctly connected to the regulator and they are clean and not damaged.

Make sure the switch on the regulator is in the off position. Turn clockwise into the 3 o’clock position.

Remove the protective cap from the gas cylinder

Place the regulator onto the valve and press down firmly until you hear a metallic click signifying the collar has locked onto the valve.

We recommend connecting your gas bottle outside of the portable heater and only placing it inside when it’s ready to use

To start using your heater, turn the regulator anti-clockwise so it’s in the 12 o’clock position.

The gas is now on. Light your portable heater as advised by the manufacturer’s instructions.

When you’ve finished using your heater, turn the switch on the regulator clockwise to the 3 o’clock position to turn the heater off.

We recommend turning the heater off at the regulator every time, this will burn off any residual gas left in the heater. If your heater has a power switch, you can also turn this off.

If you need to change your empty gas bottle, turn off the regulator and push in the button on the regulator to easily lift it off the bottle. It is now safe to replace your gas bottle.

All cylinders have a tare weight disk showing the weight of the cylinder, we then fill the bottle to the required amount it can hold. To check how much gas is remaining we would recommend using scales.

For example the total weight of a 13kg cylinder is 25kg – the bottle weighs 12kg and the gas weighs 13kg.

To check how much gas is remaining, place the bottle on a scale and check the weight. In this example, if the scales show 14kg, the original bottle weight was 12kg, so this would mean there is 2kg of gas left in the cylinder.

If you bottle is empty and you wish to either return it or order a new one you can do this either through the website shop or your account.

Simply choose the bottle you wish to order and when prompted, select yes where it says ‘Do you have a cylinder to return’. You can also check previous orders in your account if you’re unsure which cylinder you have.

You can swap your gas cylinder for any cylinder within the same category. There is no charge when swapping a cylinder within the same category.

Turn the control lever from the vertical (on position) to the horizontal (off position). With your hand over the regulator, which is usually a round metal device, normally blue in colour or it has a blue label or label that says butane connected to the bottle by a hose what controls the gas flow. Place your thumb against central spindle/shaft of control lever and press firmly towards the body of the regulator. This will release the locking collar from the cylinder valve and regulator should spring away. The cylinder can then be removed for the replacement cylinder to be positioned.
