Herz Condensate Management / Flue Slope Issue

Boiler flue terminal shows white staining and excessive condensate dripping

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

Incorrect flue slope away from Herz boiler, missing condensate drain on flue, blocked condensate trap, excessive flue length causing condensation

Safety: Condensate is mildly acidic; avoid skin contact.

Check flue slope: Visually confirm that the flue slopes back towards the Herz boiler as specified, so condensate returns to the trap.
Clean trap: Remove and clean the condensate trap to ensure free flow.
Inspect joints: Ensure all flue joints are properly sealed to prevent condensate leakage.
Correct installation: If the flue is incorrectly installed, a qualified installer must reconfigure it according to Herz guidelines.
