De Dietrich Condensate Management / Flue Installation Issue

Condensation or water dripping from the flue joints inside the property

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 on De Dietrich concentric flue, Failed flue joint seals, Blocked condensate drain, Excessive flue length without support

Safety first: Water near electrical components can be hazardous. Turn off power if water is entering the unit.

Step-by-step checks:

Inspect flue slope: The flue should slope slightly back toward the boiler to allow condensate to drain.
Check joints: Look for loose or separated flue joints and reseat if accessible.
Clean condensate trap: Ensure the condensate trap and drain are clear so condensate can flow freely.

When to call a professional: Flue reconfiguration or resealing should be done by a qualified installer.
