Opening the valve on a quantum meter

First, make sure all your gas appliances are switched off.

• Insert your gas card into the meter. Press and hold the red 'A' button until the display shows 'release' or 'let go'.
• Remove the card. After about 30 seconds you'll hear a click. That's the valve reopening.

The display can take up to another minute to change from 'Off' to 'On'. Once it does, reset your boiler and you're good to go.
