Product information

Description

The Connection kit for Vaillant VIH R 120 provides the necessary fittings and connectors to integrate the VIH R 120 unit into domestic hot water and central heating systems. Designed to match the hydraulic and potable water interfaces of the VIH R 120, the kit supplies factory-specified components that ensure correct alignment and compatibility with the unit when installed by a professional.

Advantages

The kit includes preselected connectors and fittings that correspond to the VIH R 120 interface, reducing on-site adaptation time and ensuring proper hydraulic sealing. Components are designed for potable water compatibility and reliable thermal performance within typical residential and small commercial heating systems. By providing matching parts, the kit simplifies installation logistics and helps maintain system integrity when combining the VIH R 120 with existing piping and ancillary equipment.

Suitable for

  • Integration of a Vaillant VIH R 120 into domestic hot water systems
  • Connection of the VIH R 120 to central heating circuits in residential properties
  • Use by professional heating installers and service technicians during system replacement or new installations

Key specifications

  • Set of factory-specified fittings and hydraulic connectors matched to the VIH R 120 interface
  • Components suitable for potable water contact
  • Materials selected for standard residential heating temperatures and pressures
  • Includes connectors for hot water and heating circuit connections as required for VIH R 120 integration

How to use

Installation of the connection kit should be carried out by a qualified heating engineer in accordance with local regulations and the VIH R 120 installation manual. Verify system shutdown and depressurisation before starting work. Fit the supplied connectors and fittings to the VIH R 120 unit following the unit’s port identification and torque specifications. Ensure all potable water connections are flushed and inspected for leaks before commissioning the system. After mechanical installation, complete required electrical and control wiring per the boiler documentation and perform standard commissioning and safety checks.

Usage recommendations

Use this connection kit only with the Vaillant VIH R 120 model it is designed for; confirm compatibility with the specific installation scenario and consult the VIH R 120 technical manual. Where water quality or system conditions differ from typical residential installations, evaluate component suitability and consider additional water treatment or protective measures.
