The Vaillant 0020146732 ecoTEC Pro 28 Gas Section with Venturi is a genuine replacement fuel control assembly designed to regulate and deliver the correct mixture of gas and air to the boiler’s combustion chamber. This gas section integrates a precision gas valve with a matched venturi to help control gas flow and ensure the correct air/gas ratio for efficient combustion. Proper fuel regulation and air mixing support smooth ignition, stable flame quality, improved efficiency and responsive modulation across varying heat demands. Built-in safety shut-offs protect against unsafe gas flow conditions, helping to maintain safe boiler operation.

This gas section with venturi is compatible with Vaillant ecoTEC Pro 28 boilers that reference part number 0020146732 in their technical documentation. Always verify that the part number on your existing gas section matches before installation, as gas control assemblies and venturi arrangements differ between models.

Supplied ready for direct replacement, the 0020146732 Gas Section with Venturi integrates with the boiler’s existing gas inlet, control wiring and mounting points when installed by a qualified Gas Safe engineer. Choosing this genuine Vaillant component helps restore precise gas control, supports efficient combustion and contributes to reliable heating and hot-water performance in compatible ecoTEC Pro 28 boilers.
