DURAFire® Oil Igniter

e DURAFire® can be used as a Class 1, Class 2, or Class 3 igniter,

depending on the burner capacity. e DURAFire® is easily installed as a retrot

into most burner types based on its size, capacity, and reliable operation.

e DURAFire® oil igniter consists of ve major components: a guide

tube, an atomizer/head assembly, an oil/air mixture transport tube, a spark rod,

and a stainless steel diuser for pilot stabilization. e guide tube houses the

internals, which are attached to the head and easily removed from the guide

tube for maintenance purposes by releasing a “V” band retainer, requiring no

tools. Cooling/combustion airow is directed down the guide tube to support

and maintain the primary combustion zone during operation. is controlled

mixture of fuel and air in the primary combustion zone results in a highly

reliable, stable igniter ame. While out of service, airow cools the igniter and

prevents debris from entering the end of the guide tube.

e DURAFire® oil igniter comes 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. e remaining HESI components consist of a

positioning rod, cable and power unit. Optional equipment for the DURAFire®

includes mounting hardware, retraction assembly, hoses and ame detector.

e DURAFire® oil igniter delivers the

most reliable source of energy for main

ame ignition, ame stabilization, and

boiler warm-up.
