Ignition electrode De Dietrich 7219212

An ignition electrode generates the spark needed to ignite the gas-air mixture in a burner. This electrode is exposed to extreme heat and corrosive byproducts, so it must be made of durable materials. Over time, electrodes can wear out or become fouled, leading to ignition problems. Replacing a worn ignition electrode restores reliable burner startup and improves overall heating system performance. Check electrode gap and mounting style for compatibility.
