If your auto regulator is not switching over, we recommend looking at the indicator first.
The indicator at the top of the gas regulator indicates if the gas bottle in use contains gas or is empty.
When the indicator is green, the regulator is ON and the gas bottle in use contains gas. When the indicator is RED, the regulator is OFF as the gas bottle in use is empty.
Please note, the indicator only indicates the contents of the cylinder that it is “pointing to” or “in use”. This means that the indicator can show RED when reading the first empty cylinder, even when the second cylinder has gas.
To accurately check the regulator/indicator is working – only connect or turn on one cylinder at a time and check if it is green or red and if there is gas at the outlet.
