Condensate Management for Navien water heaters

Condensing equipment produces acidic water that must drain through a trap that keeps flue gas sealed in the unit. A blocked, dry or frozen trap triggers blockage codes and shutdowns, which is why the installation and the annual service treat the drain as a first-class part of the system.

This service routes the condensate in approved material to a code-compliant drain, installs and primes the trap, adds a neutralizer where the receiving drain or local rules require one, and protects the routing from freezing in unheated spaces.

Working on a Navien unit? Have the model number from the rating plate and any code or flash pattern ready. Browse Navien series, models and fault codes to find yours; the details carry through when you request service.

Frequently asked questions

Why does my tankless unit shut down in winter?

A frozen or blocked condensate drain fills the trap and trips blockage codes. Freeze-safe routing and a drain check are part of winter service.

Is condensate really acidic?

Yes, mildly. Approved materials and a neutralizer where the drain requires one protect the plumbing.
