Product Overview
Features & Benefits
e MAXFire® Series 100 gas igniters can be used as a Class 1 , Class 2, or
Class 3 igniter, depending on burner capacity. e 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.
e 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. e
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. e HESI produces a powerful 12-joule
spark approximately three times per second at the primary combustion zone. e
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.
