The Venturi / Gas-Air Mixer on Your Buderus 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 Buderus systems — including models such as GB142, GB162, Logamax plus — a failing venturi / gas-air mixer often shows up as ignition fault or related symptoms. We diagnose it precisely and install the correct genuine Buderus part.
