The Flue & Venting on Your Navien Boiler

The flue and venting system carries combustion products safely outside and, on sealed-combustion boilers, draws intake air in. Damaged, blocked, or improperly sloped venting is a serious safety issue and a common cause of pressure and condensate faults.

On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing flue & venting often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
