Genuine Navien venturi / gas-air mixer, supplied and professionally installed by Technical Safety BC–licensed gas fitters. Never sold for DIY.
The Venturi / Gas-Air Mixer on Your Navien Boiler
On fully premixed condensing boilers the venturi draws gas into the combustion-air stream at a precise ratio before it reaches the fan and burner. A blocked or cracked venturi upsets the gas-air mix, causing combustion faults and lockouts.
On Navien systems — including models such as NCB-240E, NCB-210E, NHB-150 — a failing venturi / gas-air mixer often shows up as e003 ignition failure or related symptoms. We diagnose it precisely and install the correct genuine Navien part.
