The Ignition Electrode sparks to ignite gas, demanding proper gap spacing—typically 1/8 to 1/4 inch—to ensure reliable ignition without misfires. Over time, carbon buildup may require cleaning to maintain performance.
The Hot Surface Igniter, used in modern systems, heats up to ignite gas without a flame. It requires careful handling to avoid cracks, as thermal shock can cause failure. Both ignition components need secure electrical connections to prevent intermittent operation.
Proper installation involves testing each component for functionality, verifying gas valve shutoff response, and ensuring no leaks. Regular maintenance, such as inspecting wiring and cleaning electrodes, extends system life. By adhering to these guidelines, technicians ensure reliable, safe operation in residential and commercial gas-fired appliances.
