DESCRIPTION

The High Energy Spark Igniter (HESI) 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 presence
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 HESI models are available to fit a variety of igniter or burner types.

    SAFETY Safety is the responsibility of each individual who installs, operates, or maintains Fireye equipment. The Fireye design of the HESI includes personnel safety as a basic design element. The HESI assembly uses a 2000-vdc energy source to produce a 12-joule spark for fuel ignition purposes.

    POWER PACK INSPECTION AND MAINTENANCE The following steps describe power pack inspection and maintenance. Disconnect all electric power from the power pack, and ensure that all residual voltage is dissi- pated. (See Safety section.) Open the power pack door. Test capacitor C1 for resistance across terminals 1 and 2. Test transformer T1 for resistance at the two red secondary leads.
