Connecting Regulators - Snap-on Butane

How to connect a snap-on butane regulator

The CALOR range of Butane gas cylinders feature a 21mm valve fittting. If you're unsure of compatibility, check the underside of your regulator for the diameter of the fitting.

Step 1

Turn the orange safety cap towards the centre of the gap in the shroud. Pull on the black lanyard to remove the orange cap.

Step 2

Once you have removed the orange cap, check to see that the black washer is fitted inside the cylinder valve.

Step 3

Before connecting the regulator, ensure the regulator switch is in the disconnect position.

Step 4

Place the regulator on top of the cylinder valve and push down firmly until you hear a click.

Step 5

When you need to use the gas, turn the switch anti-clockwise to the 'on' position.

We strongly advise that when fitting any gas regulator that you should follow the manufacturers instructions. Most snap-on regulators operate much the same, however the various designs are wide ranging. When you're finished using your appliance, reverse Step 5 to stop the flow of gas.

Note: If you find that the on/off switch requires excessive force when turning the supply on, you may need to repeat Steps 1 to 5 as the regulator may be incorrectly fitted.

Step 2
