Section 1 Description
The MAXFire
®
gas igniter is a versatile and reliable source of ignition energy for oil, coal, or natural gas
burners. It is a self-contained unit that features a stable and clean-burning flame, repeatable fuel ignition,
low maintenance (no moving parts), and low combustion/cooling air requirements.
Depending on the burner capacity, the MAXFire
®
gas igniter may be sized for use as an NFPA-rated
Class 1, Class 2, or Class 3 igniter. Class 1 igniters are used for burner light off and support. Class 2
igniters are used for light off and support under prescribed light off conditions. Class 3 igniters are used
for light off only and are not intended for warm-up or support.
MAXFire
®
igniters are available in a variety of hardware configurations to fit the customer’s installation
requirements and operating preferences. In addition to the standard assemblies, other capacities can be
provided on request.
The major components of the igniter assembly are a guide tube, ignition source, and view port. Figure
