Inlet and outlet set - for boiler modules DN 25 PAW.VN 3461

Product detailed description

Boiler modules in central heating systems require dedicated access points for maintenance and system management. This includes the ability to fill, drain and flush the system during installation or servicing. The IVAR 3461 DN 25 set is designed for such applications, typically found in residential and commercial buildings with hydronic heating systems. Installers working on boiler room layouts or retrofitting older systems will find this set useful for ensuring efficient and safe system operation.

Direct installation above the boiler module ensures minimal space requirements and secure access. The set is commonly used in systems where periodic maintenance is required, such as in multi-family dwellings, small commercial buildings or industrial facilities with compact boiler arrangements. The design allows for quick access to the system’s hydraulic circuit without disrupting the boiler’s primary function.

Technical parameters

Installation and connection

The set is installed directly above the boiler module, using the included mounting bracket to secure the T-piece. The connection is made via DN 25 threaded or flanged fittings, depending on the boiler module’s design. Installers should verify that the module’s inlet and outlet ports match the set’s nominal diameter and thread type before assembly. A common mistake is misalignment of the mounting bracket, which can lead to stress on the piping and potential leaks. The filling and drain valve should be positioned for easy access during operation and maintenance.

Compatibility and accessories

The IVAR 3461 DN 25 set is specifically designed for boiler modules in the PAW series. It is compatible with standard DN 25 piping and fittings used in heating systems. No additional components are required for installation, as the set includes all necessary parts for immediate use. The set is intended for direct integration with boiler modules and is not designed for use with other types of heating equipment.

Technical background for designers

The set operates as a manifold for system filling and draining, with the T-piece allowing for the connection of a filling or drain hose. The materials used are selected for their resistance to thermal expansion and corrosion, ensuring long-term reliability in heating systems. The design allows for integration into the boiler module’s hydraulic circuit without affecting the module’s primary function. The efficiency and service life of the set depend on correct installation, including secure mounting and alignment with the boiler module’s ports.

Service and operation

Periodic inspection of the valve and mounting bracket is recommended to ensure continued functionality. The valve should be checked for signs of wear or leakage, particularly after system draining or flushing. No specific service intervals are provided in the technical data, but maintenance should be carried out in accordance with the manufacturer’s guidelines for the boiler module. The set does not require regular servicing beyond visual inspection and functional testing.
