The MAXFire® Series 100 gas igniters can be used as a Class 1, Class 2, or Class 3 igniter, depending on burner capacity. The MAXFire® igniter is easily installed as a retrofit into most burner types based on its size, capacity, and reliable operation.
MAXFire® gas igniters consist of four major components: a guide tube, a gas transport tube, a spark rod, and a stainless steel diffuser for pilot stabilization. The guide tube houses the spark rod and the gas transport tube, which are easily removed from the guide tube for maintenance purposes by releasing a “V” band retainer, requiring no tools. Cooling/combustion airflow is directed down the guide tube to support and maintain the primary combustion zone during operation. The controlled mixture of fuel and air in the primary combustion zone results in a highly reliable, stable igniter flame. While out of service, airflow cools the igniter and prevents debris from migrating into the end of the guide tube.
MAXFire® gas igniters come standard with Forney’s High Energy Spark Igniter (HESI) as the spark source. The HESI produces a powerful 12-joule spark approximately three times per second at the primary combustion zone. The HESI spark tip is a nonfouling, surface-gap tip which is replaceable as a unit by a threaded connection. Optional equipment for the MAXFire® includes a High Tension Spark (HTSI) source in place of the HESI, mounting hardware, hoses, flame rod and an integral or externally mounted optical flame detector.
