FURNACE IGNITORS
Robertshaw’s 41-400 Series Norton Hot Surface Ignitors deliver dependable
ignition in heating systems of every description. From furnaces and boilers to
rooftop heaters, infrared burners, unit heaters, water heaters and many other
types of HVAC equipment.
The 41-400 Series Hot Surface Ignitors are made of high-purity recrystallized
silicon carbide (Crystar™) which combines physical and thermal strength with
stable electrical properties. The 41-400 Series are designed to reach ignition
temperature(s) within 17 seconds. They have 18-gauge nickel chrome lead
wires embedded and metalized in place for maximum holding strength and
electrical conductivity. The lead wires are also enclosed with a special high-
temperature fiberglass insulation providing total electrical protection.
NOTE: All 41-400 series ignitors are 120 VAC models. Some hot surface
modules are rated for 208/240 volts input, however they step the voltage to
ignitor down to 120 VAC.
