The burner assembly is the part of a gas water heater that mixes and ignites fuel to produce heat. It includes the burner, ignition system (pilot or electronic igniter), and controls that regulate gas flow and safe operation. A clean, properly adjusted burner assembly ensures efficient heating and reduces risks like soot buildup and carbon monoxide.

Clean burners and proper ignition improve safety and efficiency.
In a home, the burner assembly ignites whenever hot water is needed, providing reliable heating for showers, laundry, and cleaning.
Schedule annual burner inspections and cleanings to maintain efficient combustion and safe operation.
“Schedule annual burner inspections and cleanings to maintain efficient combustion and safe operation.”
High-efficiency condensing water heaters capture extra heat from exhaust gases, using advanced burner designs to improve efficiency.
What color should a burner flame be?
A steady blue flame is ideal. Yellow or orange flames can indicate dirty burners or poor combustion.
Can I clean the burner assembly myself?
Basic cleaning is possible, but fuel and ignition components should be serviced by a professional for safety.
What causes soot around the burner?
Incomplete combustion, dirty burners, or improper airflow can lead to soot buildup and should be inspected.
