Why Does My Boiler Make A Banging Noise When Firing Up

You see, during normal operation, when a gas boiler receives the call for heat, the gas valve opens and releases a small amount of gas into a sealed combustion chamber via small "jets". That gas is then ignited by the pilot light and the jet flames heat up a "heat exchanger". That heat exchanger then is used to heat water.
