Sta-Rite Sooting/Incomplete Combustion

Soot or black staining is visible on top of the heater or around the exhaust outlet.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Restricted air intake, incorrect gas pressure, dirty burners, blocked heat exchanger passages.

Safety: Turn off gas and power. Soot indicates dangerous combustion; address this immediately.

Inspect air openings: Ensure all combustion air openings on the Sta-Rite cabinet are clear of leaves, dirt, or obstructions.
Clean burners: Remove and thoroughly clean the burner tray, removing rust flakes and debris from the burner ports.
Check venting: For vented installations, verify that the vent is not blocked and is correctly sized.
Have combustion checked: A qualified technician should measure combustion parameters and adjust gas pressure or orifices as needed.
