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
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
