Maxon 18118 Spark Ignitor

The Maxon 18118 Spark Ignitor is a critical high-voltage combustion ignition component engineered specifically for industrial gas-fired equipment, including Maxon burners, gas turbine engines, and high-capacity boilers. Featuring a precision 18mm electrode, this ignitor delivers a consistent high-energy spark to ensure reliable fuel-air mixture ignition, eliminating the need for inefficient pilot lights and reducing instances of incomplete combustion. Built with a high-grade nickel-chromium alloy electrode and a thermal-resistant ceramic insulator, the 18118 is designed to maintain electrical integrity under the extreme heat of steady-state burner operation.

This replacement spark plug often comes equipped with a Rajah E9-SSN connector to facilitate a secure, vibration-resistant connection to the ignition transformer. For technicians performing routine maintenance on industrial oven parts or process heating systems, the Maxon 18118 18MM Spark Ignitor provides a drop-in solution that ensures flame signal stability and consistent light-offs. Its compact design allows for installation in tight burner housings, making it a standard choice for HVACR contractors managing large-scale thermal processing applications. Proper electrode gap settings should be verified during installation to prevent carbon fouling and ensure optimal arc performance.

• Efficient Ignition: Delivers a 10-15kV spark for immediate ignition of gas burners, improving overall system safety.
• Industrial-Grade Materials: The nickel-chromium alloy construction resists corrosion and heat deformation for extended service life in 24/7 operations.
• Seamless Integration: Designed as a direct OEM replacement part for diverse Maxon burner configurations, including gas turbines and boilers.
• Enhanced Safety: High-voltage performance ensures positive ignition, preventing gas buildup and potential flame-rollout issues.

Is the Maxon 18118 compatible with all gas-fired burners?
While the 18118 is a standard 18mm spark ignitor, it is essential to verify the specific bore size and electrode length of your burner model. It is widely used in Maxon's industrial line, but always check your technical manual for part number compatibility.

Can I test this ignitor with a standard multimeter?
No, standard meters cannot handle the 10,000+ volts generated during the ignition cycle. Technicians should use an inline spark tester or perform a continuity test on the electrode while the power is disconnected to ensure the internal rod is not cracked.

How often should I inspect the 18mm electrode?
The electrode should be inspected during every scheduled maintenance window for carbon buildup, ceramic cracking, or erosion of the nickel-chromium tip to ensure consistent ignition performance.
