    Not getting gas?

    Is it natural or LP? Check the regulator outside and make sure its vent isn't blocked by snow or ice.

    Could also be a bad gas valve, but if you don't have a digital manometer and are not trained to use it, then that cannot be confirmed.

    If it is the gas valve, and you replace it, then the manometer and combustion analyzer should be used to adjust it when the boiler is fired off again.
