Vaillant 3816 Ecotec Spacer Frame 308650 105291

The Vaillant 3816 ecoTEC Spacer Frame is an accessory designed for use with compatible Vaillant ecoTEC boilers. This spacer frame is fitted to provide additional clearance between the boiler and the wall surface when space or pipework routing constraints are present.

On site, installers typically use the spacer frame to simplify maintenance access or to make pipework connections more manageable during or after installation. It is particularly useful in tight plant rooms or residential properties where pipe runs must pass behind the appliance.
