SureFire Igniters

The SureFireTM gas igniters are a versatile and reliable source of ignition energy for oil, coal, or natural gas burners. They are self-contained units and feature a stable and clean-burning flame, repeatable fuel ignition, low maintenance (no moving parts), and low cooling/combustion-air requirements.

The SureFireTM gas igniters are NFPA-rated as a Class 1, 2, or 3 igniter, depending on the application: Class 1 igniters are used for burner light-up and support under any conditions; Class 2 igniters are used for light-up and support under prescribed light-off conditions; and Class 3 igniters are used for light-up only and are not intended for warm-up or support.

These igniters are provided with a durable High Energy Igniter (HEI) for repeatable light-off. Refer to the HEI bulletin for detailed HEI information.

In most applications, the self-contained SureFireTM gas igniters are mounted in a burner through a mounting tube. The major components of the SureFireTM gas igniters are the guide tube assembly, and the HEI. Figure 1 shows the SureFireTM igniter assembly. 

Nonfouling 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.

Removeable 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 pack to the spark rod assembly ensuring operator safety.

Application Flexibility –

Standard and retractable HEI models are available to fit a variety of igniter or burner types.
