Baso B04S-1E405 Hot Surface Ignitor 120V Silicon Carbide

Product Description

The BASO B04S-1E405 is a silicon carbide hot surface ignitor rated at 120 volts AC, designed to ignite the main burner in gas-fired heating equipment. Hot surface ignitors replace standing pilot assemblies and spark ignition systems in modern furnaces and boilers, offering reliable, repeatable ignition on each call for heat. Silicon carbide construction provides high thermal conductivity and fast heat-up times, allowing the ignitor to reach ignition temperature quickly. This part is installed by licensed HVAC technicians during routine maintenance, seasonal startup, or emergency no-heat service calls.

The B04S-1E405 is suited for residential and light commercial gas heating applications where a 120-volt hot surface ignition system is specified. Typical installations include forced-air gas furnaces and gas-fired boilers that use a hot surface ignitor as the primary ignition source. Installers should verify voltage requirements and mounting configuration before ordering to confirm fitment with the existing ignition control system.

Key Features

• Silicon carbide element for fast heat-up and durable ignition performance
• 120-volt AC operating voltage compatible with standard residential and commercial ignition control boards
• Direct replacement style for hot surface ignition systems
• Rugged construction suited to the high-temperature environment of a gas burner assembly

Compatibility

Designed as an OEM-style replacement for gas furnaces and boilers equipped with 120-volt hot surface ignition systems.

Installation Notes

Hot surface ignitors are installed by licensed HVAC technicians. Always shut off power to the unit at the disconnect and allow the ignitor to cool completely before handling, as silicon carbide elements are fragile and can crack from mechanical shock or skin oils. Avoid touching the ignitor element with bare hands during installation. Follow the equipment manufacturer's wiring diagram and applicable local codes when reconnecting the ignitor harness to the control board.
