Gas Furnace Repair and Troubleshooting - The Spruce
Newer conventional furnaces do not rely on a standing pilot to ignite the gas burners, but rather make use of electronic components. Electronic ignition occurs typically in one of two ways: intermittent pilot or hot surface ignition. The intermittent pilot system uses an electronically controlled high-voltage electrical spark to ignite the gas pilot, which subsequently lights the main burners

Why Does My Boiler Make A Banging Noise When Firing Up
Just check out our blog, "How a Boiler Works". But "delayed ignition" is when the gas that's sent into the combustion chamber isn't ignited immediately. And when that happens, gas builds and builds inside the combustion chamber until BANG—the pilot light finally ignites all that gas, creating a mini-explosion.
