Connection fitting for MCA/DTG 65, 90, 115 100002310

Complete hydraulic kit for De Dietrich MCA and DTG boilers

This kit is a ready-made solution for the hydraulic connection of De Dietrich MCA and DTG series condensing gas boilers with outputs of 65, 90, and 115 kW. Instead of selecting individual fittings, the installer receives everything necessary for a safe and project-compliant installation of the heating circuit in a single package. This approach eliminates the risk of errors in selecting diameters or types of connectors, which is crucial when working with high thermal output devices.

Thanks to its pre-assembled design, installation time is significantly reduced, and the system is immediately ready for connection to supply and return pipelines. The kit ensures proper sealing of connections and correct geometry of the heating medium flow, resulting in stable boiler operation and optimal efficiency of the entire heating system.

Application and benefits for installations

The primary purpose of this kit is to serve boilers with outputs ranging from 65 to 115 kW, positioning it in the segment of equipment for large single-family homes or public utility buildings. In the case of such high outputs, correct execution of hydraulic connections is a prerequisite for installation safety.

• Universality for MCA/DTG series: The kit has been specifically designed for models MCA 65/90/115 and DTG 65/90/115, ensuring perfect dimensional fit without the need for additional adapters.
• Ready for installation: The installer does not need to source additional components such as shut-off valves or air vents – they are already an integral part of the kit.
• Operational safety: Properly selected fittings minimize the risk of leaks at critical points where large volumes of hot water flow under pressure.
• Error prevention: Eliminating the need for manual selection of parts reduces the chance of mistakes during purchase or installation, which is especially important during service work or modernizations.

Construction and compliance with technical requirements

The product is supplied as a complete hydraulic connection kit (HC139), meaning all components are synchronized in terms of flow parameters and operating pressure. Such integration of elements allows for maintaining the correct hydraulic characteristics of the circuit, which is essential for the efficiency of condensing boiler operation.

The kit is dedicated exclusively to condensing gas boilers with outputs of 65 kW, 90 kW, and 115 kW from the MCA and DTG families. Thanks to this solution, the installation meets the manufacturer's requirements (De Dietrich / BDR Thermea Poland Sp. z o.o.), which is necessary to maintain the warranty and ensure proper system diagnostics in the future. There is no room for guesswork – this is a dedicated spare part designed to connect directly to the boiler casing without gaps or the need for non-standard adapters.

It is worth noting that for boilers with such high outputs, specific solutions regarding flue gas removal or heat exchange are often required – this fitting kit covers exactly that part of the water installation which directly interfaces with the boiler casing. For a professional, this means less time checking component compatibility and certainty that, once commissioned, the boiler will operate under optimal heating water flow conditions.
