Auburn E5-I-31-2 Ignitor
The Auburn E5-I-31-2 Ignitor is a high-performance industrial spark igniter specifically engineered for demanding combustion systems. Built with a nickel electrode and a robust 14mm x 1.25mm thread, this Auburn ignitor (alternative part CS13238) ensures reliable ignition in burners, heaters, and ovens. Its 3.68-inch overall length and 2.50-inch insertion depth are designed for precise fitment in standard HVACR and industrial configurations. By utilizing advanced ignition technology, the E5-I-31-2 is highly resilient to thermal shock and chemical erosion, making it an ideal choice for HVAC replacement parts. Whether you are maintaining a commercial boiler or a specialized furnace, this component provides the durability and consistent spark required to maintain optimal burner performance. The 13/16-inch hex size allows for straightforward installation, ensuring that your ignition control sequence remains efficient and uninterrupted in harsh environments.
Key Benefits
- Industrial Grade Durability: Engineered with a premium nickel center electrode that resists sparking erosion and chemical degradation.
- Precision Engineering: Features a standard 14mm thread and specific 2.50-inch insertion length for accurate placement within the combustion flame.
- Thermal Shock Resistance: The high-quality insulator material is designed to handle rapid temperature fluctuations without cracking.
- Direct OEM Alternative: Specifically designed to replace the Auburn I-31-2 and CS13238 models for seamless compatibility.
Common Questions
Is the E5-I-31-2 compatible with older I-31-2 models?
Yes, the 'E5' prefix is the modern designation for the standard I-31 series. As long as your dimensions and thread size match, this is the correct technical replacement.
What tools are needed for installation?
A standard 13/16-inch hex socket or wrench is required to secure the ignitor into the mounting port.
Can this be used for flame sensing as well?
While primarily a spark ignitor, many Auburn components are used in dual-purpose applications; however, you should always consult your equipment's wiring diagram to ensure proper feedback loop integration.
