T HE MAXF IRE 40 L OW P RESSURE G AS I GNITER PROVIDES A RELIABLE SOURCE OF ENERGY FOR MAIN FLAME
IGNITION , FLAME STABILIZATION , AND LOW GAS PRESSURE APPLICATIONS . Depending on the burner capacity, the
MAXFire can be used in a class 1 , class 2 , or class 3 application. This igniter can be easily installed
as a retrofit into most types of burners because of its size, capacity, and reliable operation.
The MAXFire Gas Igniter consists 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. No tools are required.
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, this airflow cools the igniter and prevents debris from migrating into the end of
the guide tube.
The MAXFire Gas Igniter is provided with Forney’s HESI 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. The MAXFire is also available with a High Tension
Spark (HTSI) source in place of the HESI. Optional equipment for the MAXFire Gas Igniter
includes mounting hardware, hoses, valves, and optical flame detector.
