    Step 1. Shut off power to the house.
    Step 2. Leave.
    Step 3. Get somebody competent to find the gas leak.

    A gas leak is a gas leak. It is also an explosion waiting to happen. I don't want to read about you in the papers. Or on the 'net.

    If you insist on living very dangerously, at least do your neighbours a favour and get the gas shut off to your house at the service entrance.

    @pumbaa Hi there, yes years later, but I’m having the same thing at a customers house and im just wondering what you ended up doing? Just change the board or the gas valve as well? It’s almost 8pm here on a Friday so I can’t get tech support..
