Honeywell Pilot burner Q382A2009/B

This pilot burner carries a small permanent or intermittent pilot flame. The flame lights the main burner and provides a flame signal for the control system. Flame sensing is performed by an ionisation electrode, while ignition uses both an ignition electrode and an ionisation electrode. The insulator is made of ceramic.

Parts of this type are selected by matching electrode geometry—length, bend, insulator diameter, and spark gap—to the burner series they were shaped for. The mounting flange must also align with the burner head. In systems where the pilot burner is integrated, the unit typically houses both the ignition electrode and the ionisation electrode, though the specific arrangement depends on the burner design. Always verify the burner model and compare the physical dimensions of the replacement directly against the original unit.

Common wear patterns include eroded spark tips, cracked ceramic insulators, soot build-up from incomplete combustion, and a drifting electrode gap that lengthens the ignition time. These signs may be visible when inspecting the burner.
