Pilot Assemblies

HVAC pilot assemblies are small, controlled burners that are constantly lit, and this flame is what ignites the main burner when the thermostat calls for heat. The flame is also essential for safety, as it confirms the presence of gas in the system before activating the burner. Because of this, they are essential components for code-compliant operations, preventing gas leaks or system lockouts. Gas flow without ignition is not only a safety risk; it can also lead to energy waste and increased costs.

If the flame in a pilot assembly is weak or ignition is inconsistent, you may need to replace the pilot assembly. It’s best practice to inspect these during routine maintenance to ensure proper operation. Failed pilot assemblies will result in failed ignition, and therefore no heat or frequent lockouts. Ensuring these are operating correctly is the best way to prevent HVAC service calls or occupant complaints.
