Vaillant Clamp DN 100 Kit 30, 40mm 0020231438

The Vaillant Clamp DN 100 Kit (Part No. 0020231438) is a specialized genuine OEM fixing designed for the secure installation and structural support of 100mm flue systems. This clamp is essential for maintaining the integrity of the outer air duct in Vaillant’s concentric flue systems, ensuring that extensions and elbows remain firmly connected and correctly aligned. The "Kit 30, 40mm" designation refers to the specific bracket or spacer dimensions included to ensure the flue maintains the required clearance from wall or ceiling surfaces.

Key Features and Specifications
DN 100 Compatibility: Specifically engineered for the 100mm Outside Diameter (OD) air duct used in standard 60/100mm concentric flue systems.

Structural Stability: Prevents flue segments from sagging or pulling apart due to thermal expansion and contraction, which is a critical safety requirement.

Kit 30, 40mm: Includes the necessary hardware to provide a 30mm or 40mm "stand-off" distance, ensuring the flue is supported at the correct pitch (3° gradient) back to the boiler.

Genuine Vaillant Part: Manufactured to the exact tolerances required for Vaillant flue gas systems, ensuring compliance with Gas Safety (Installation and Use) Regulations.

Corrosion Resistant: Built from high-quality treated steel or reinforced polymers to withstand the environment of a boiler room or utility space.

Installation and Safety
According to Vaillant installation manuals, every flue extension must be supported by a pipe clamp. The distance between two clamps must not exceed 2 meters, and a clamp should always be installed near a change of direction (elbows).

Important Safety Note: The installation of any flue-related component must be carried out by a Gas Safe Registered engineer. Improperly supported flue pipework can become disengaged, leading to the leakage of dangerous combustion gases (Carbon Monoxide) into the property.
