  • High-Temperature Durability: Features a robust ceramic and metal construction designed to resist oxidation and thermal stress in the combustion chamber.
  • Enhanced System Safety: Provides reliable spark ignition, reducing the risk of delayed ignition and hazardous gas buildup.
  • Optimized Efficiency: Maintains consistent pilot flame performance, helping to stabilize burner operation and maximize overall fuel efficiency.
Common Questions

What models are compatible with the 100109827 ignitor?
This igniter pilot assembly is commonly used in Lochinvar ERN pool heaters and A.O. Smith residential power vent water heaters. Always cross-reference your specific model and serial number before installation.

Can I use this for both Natural Gas and Propane units?
While the igniter itself generates the spark for both fuel types, ensure the surrounding pilot tubing and orifice are correctly sized for your specific gas type (NG or LP) as per the manufacturer's technical specifications.

Why is my pilot failing to light despite a visible spark?
If the spark is present but ignition fails, check for obstructions in the pilot tube or a faulty gas control valve. Ensure the electrode is properly positioned relative to the burner head for optimal flame crossover.
