DESCRIPTION
The High Energy Spark Igniter (HEI) is a Class 3 (special) igniter used for direct spark ignition of oil
or gas igniters or small burners. The 12 joules of power delivered to the spark tip easily ignites the
fuel. Three sparks per second are delivered. The High Energy Spark Igniter consists of three major
components: a power pack, a spark rod, and a cable.
The power pack is packaged in a NEMA-4 or NEMA-4X enclosure suitable for wall mounting at the
burner front. The power pack develops the 12 joules of power delivered to the spark tip through the
use of heavy-duty electrical components. It has a 100% duty cycle at temperatures up to 130° F
ambient.
The spark rod features a self-cleaning surface gap spark tip that is easily replaceable through a
threaded connection. Spark rods are available with an optional retraction assembly to allow the spark
tip to be inserted and retracted from the firing position.
FEATURES
Non-fouling Spark Tip
The surface gap spark tip produces a self-cleaning, highly reliable, 12-joule spark even in the pres-
ence of moisture, oil, and carbon deposits.
Removable Spark Tip
The spark tip completely detaches from the spark rod through a threaded connection. Replacement
of the spark tip is quick and easy.
Safe Operation
Heavy-duty, UL-approved flexible cable connects the power unit to the spark rod assembly ensuring
operator safety.
Application Flexibly
Standard and retractable HEI models are available to fit a variety of igniter or burner types.
