Light The Way

SURE THING
It goes without saying that when winter rolls in you want your furnace to start up with no problems. That's why the system that controls the ignition function is such an integral component.

The Lennox SureLight™ ignition system utilizes the latest technology and most rugged materials available to provide reliable performance.

SMART & STRONG

For over 100 years, people have trusted Lennox to make their lives more comfortable. That's a tradition and a responsibility we take seriously. Because people trust us with the comfort of their biggest investment - their home - as well as the year-round comfort of their families, we continually challenge ourselves to come up with new and better ways to kelp them enjoy the great indoors.

That's the spirit that has gone into the SureLiglit™ ignition system.

The SureLight igniter is made of a virtually unbreakable material - silicon nitride - which is a welcome improvement from the more fragile igniters made of silicon carbide. But the igniter is just half the story.

The SureLight ignition system also features a patented "adaptive technology" control module that's intelligent enough to determine just how much energy is needed to light the burners without overheating the igniter. No other hot-surface ignition system is as reliable.

LIGHT YEARS AHEAD
SureLight ignition system is a dramatic advancement in comfort technology. Accelerated life cycle testing conducted on the igniter has proven its remarkable reliability. In fact, life cycle tests have shown that Lennox' Surelight system actually has a greater life expectancy than you. That's the kind of performance, innovation, safety and reliability you've come to expect from the company you trust.
