Lochinvar & A.O. Smith 100208513 Module

The Lochinvar & A.O. Smith 100208513 Module is a critical intermittent pilot ignition control engineered for high-performance gas-fired boilers and commercial water heaters. This OEM ignition module (cross-referenced as Honeywell S8610U3009) manages the sequence of operation for the pilot flame, main burner, and flame rectification. Built for reliability in demanding mechanical rooms, it operates on a standard 24 VAC control voltage and supports both natural gas and liquid propane configurations. For technicians troubleshooting a no-spark condition or erratic burner cycles, this module provides field-selectable pre-purge timing (0 or 30 seconds) and adjustable trial for pilot ignition (15 or 90 seconds), allowing for precise calibration based on the specific appliance vent length and gas pressure requirements.

Designed to replace legacy part numbers including RLY1131, RLY2900, and 100167752, the 100208513 ensures 100% shutoff upon ignition failure to prevent hazardous gas accumulation. This electronic ignition module is frequently found in Lochinvar Charger (CNR/CLR) series and various A.O. Smith commercial water heaters. Its robust circuitry is rated for a 1.0A pilot valve and 2.0A main valve load, maintaining stable operation in ambient temperatures up to 165°F. By utilizing flame rectification technology, the control monitors the pilot flame with high sensitivity, ensuring the main gas valve only opens when a safe pilot is established, thus protecting the heat exchanger and burner assembly from thermal stress and improper combustion.

Key Benefits:
  • Broad Compatibility: Serves as a direct replacement for Honeywell S8610U series and multiple Lochinvar/A.O. Smith legacy ignition controllers.
  • Field Flexibility: Features dip switches or selectable jumpers for pre-purge and trial-for-ignition settings to match varied application specs.
  • Safety Logic: Engineered with a 2-second maximum flame failure response time and automatic retry sequence to minimize system lockouts.
  • Dual Fuel Support: Fully compatible with Natural Gas and LP Gas systems, providing versatile inventory for service trucks.
  • Durable Infrastructure: Heavy-duty construction designed to withstand the high-cycle demands of commercial HVACR environments.
Common Questions:

What does it mean if the module sparks but the pilot won’t light?
This typically indicates a restriction in the pilot tubing, a faulty pilot gas valve, or improper gas pressure. Ensure the 24V ground is solid, as a weak ground can prevent the flame rectification signal from reaching the module, even if a spark is present.

Can I use this to replace a standing pilot system?
No, this module is specifically for intermittent pilot systems. Converting a standing pilot to an intermittent pilot requires a complete kit including the pilot burner, gas valve, and wiring harness to comply with local safety codes.

How do I verify if the module is defective or if it’s a sensor issue?
Measure the microamp signal from the flame sensor during the pilot trial. If the signal is stay above 1.0 μA but the main valve doesn’t drop in, the module internal relay may be compromised. Always check the high-voltage ignition cable for cracks or carbon tracking first.
