How to connect a Patio gas bottle (Green Bottle)

Patio gas bottles have a 27mm valve, so they should only be used with 27mm clip-on gas regulators. There’s no protective cap, so make sure the top of the valve is clean and free from debris. The regulator switch should start in the off position (3 o’clock position).

If the gas regulator on/off switch gets stuck when turning the supply on, this means the regulator hasn’t been connected correctly. If this happens, disconnect the regulator and start again.

These cylinders have a 21mm valve and can only be used with 21mm regulators. 

To remove the safety cap from cylinder valve make sure that the arrow on the cap is pointing to the gap in the shroud. It can then be removed by pulling the lanyard (plastic tie) out, and then upwards. Avoid using tools for this and just leave the cap hanging.

IMPORTANT: If the regulator on/off switch gets stuck when turning the supply on, it means the regulator has not been connected correctly. If this happens, disconnect it and follow the instructions to reconnect it.
