Supco FLS014 Flame Sensor 4" 45° Offset for Hot Surface Ignition Systems

The Supco FLS014 is a professional-grade flame sensor designed to replace many popular sensors in modern furnaces that use hot surface ignition (HSI) or direct spark ignition systems. This replacement sensor features a 4-inch length with a 45-degree offset angle, making it compatible with Carrier furnace models.

Key Features:

• Alumina ceramic insulator provides superior electrical isolation and heat resistance
• Kanthal flame rod material withstands temperatures up to 1800°F
• 45-degree offset design for proper flame positioning
• 4-inch total length for precise fitment
• Compatible with both spark ignition and flame sensing applications
• Can be mounted on multiple burners or adjacent to igniter

OEM Cross-References: This sensor replaces Carrier part numbers LH33WZ511, LH33WZ515, LH680012, LH680014, LH680534, and LH33ZS004.

Designed for use in hot surface ignition systems, this flame sensor provides reliable flame detection to ensure safe furnace operation. The durable Kanthal rod material and ceramic insulator construction deliver long-lasting performance in high-temperature environments.
