Crown Wind-Induced Flue Disturbance

Boiler locks out intermittently during windy conditions without a clear error code.

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

Improper flue termination location, inadequate wind protection on the vent kit, negative pressure in the boiler room, or loose vent joints.

Safety: Flue gas spillage is hazardous. If you suspect exhaust is entering the building, shut down the boiler and ventilate the area immediately.

Inspect vent termination: Ensure the Crown vent kit is installed according to the manual, with correct orientation and clearances from corners, soffits, and other structures.
Check joints: Verify that all vent joints are properly cemented or gasketed and mechanically secured.
Room air: Ensure the boiler room has adequate combustion air openings and is not under strong negative pressure from exhaust fans.
Consult installer: In very windy locations, a different termination or vent routing may be required.
