The Vaillant 0020144596 Adapter is a genuine flue system component designed to enable a 60 mm diameter flue connection to a 100 mm flue run on compatible boilers. This adapter allows correct integration between differently sized flue pipes while maintaining a secure, sealed pathway for combustion gases to be expelled safely to the outside. Proper flue adaptation helps preserve correct draft conditions, supports efficient combustion and ensures compliance with flue routing requirements.

This adapter is compatible with Vaillant ecoTEC Plus VUW and ecoTEC Pro VUW series boilers that specify part number 0020144596 in their flue system documentation. To ensure correct fitment and reliable performance, always verify that the part number on your existing adapter or flue component matches before installation, as flue junctions and diameters vary between models and system configurations.

Supplied ready for direct fitment, the 0020144596 Adapter installs into the boiler’s flue connection and mates with the corresponding 60 mm and 100 mm flue sections when installed by a qualified engineer. Choosing this genuine Vaillant component helps maintain safe, efficient flue gas evacuation and supports dependable operation in compatible ecoTEC Plus VUW and ecoTEC Pro VUW systems.
