This is an authentic Sure Flame replacement part. This ignitor plug is commonly used in heaters. Ignitor plugs are similar in function to a spark plug, they take voltage and create the spark needed to ignite the fuel/air mixture in the combustion chamber. The main difference is once the mixture has ignited and the flame is sustaining itself the ignitor stops firing, where a spark plug would continue to fire while the equipment is running. The ignitor plug does not need to continue to fire because the flame itself provides a constant source of ignition for the fuel/air mixture travelling through the heater. This replacement part is sold individually.
