Lochinvar & A.O. Smith 100208503 Module R-410A Key Benefits Enhanced Thermal Tolerance:

Key Benefits Enhanced Thermal Tolerance: Equipped with a Class H coil to handle high-temperature environments that cause standard coils to burn out

Durable Construction: High-grade steel blades riveted for industrial-strength performance

ensure the plunger and valve stem are free of mineral buildup to prevent inrush current failures and extend the service life of the electromagnetic operator

this component is designed for both local and remote flame sensing configurations where the sensor is mounted separately from the spark electrode to monitor the main burner flame

Durable Construction: High-tensile strength core resistant to permeation and thermal degradation

Lochinvar & A.O. Smith 100208503 Module R-410A Key Benefits Enhanced Thermal Tolerance:The Lochinvar & A. O. Smith 100208503 Module is a critical ignition control module designed for high performance direct spark ignition within EB and EW series water heaters and commercial boilers. Specifically engineered for Lochinvar EB EW 100 300 models, this 120 VAC component manages the precise timing of the hot surface igniter and gas valve to ensure consistent combustion cycles. As a cross referenced replacement for RLY2400 and RLY2400K, it
