Description
The MAXFire® 100 Series gas igniter incorporates the “protected primary combustion zone” design in each of the 5 capacities available. The ignition process starts inside the guide tube away from the burner environment resulting in an extremely stable and reliable igniter. Capacities (nominal) range from 1 mmBtu/hr to 50 mmBtu/hr.
MAXFire® gas igniters provide the most reliable source of energy for main flame ignition, flame stabilization, and boiler warm-up.
