What does it mean when your boiler won’t ignite?
However, if it doesn’t, you may need to dig a little deeper. The gas valve controls the amount of gas that can flow into the boiler for burning. When more heat is needed, more gas is allowed in and the opposite occurs when your house has reached its set temperature.
