Tryska DC0140

Product detailed description

This ceramic nozzle is part of the combustion system in selected ATMOS solid fuel boilers, ensuring efficient air flow and combustion control. It is typically installed in residential and commercial heating systems where solid fuel boilers are used for central heating applications. The design allows for precise regulation of airflow to the combustion chamber, which is critical for maintaining stable and efficient burn conditions.

Installers working with these models must ensure proper alignment and sealing during installation to prevent air leaks and maintain boiler efficiency. The nozzle is typically mounted within the boiler casing and connected to the combustion chamber through a defined interface. Compatibility with specific model variants and production dates is essential for correct function.

Technical parameters

Installation and connection

Installation requires alignment of the nozzle with the combustion chamber and secure mounting using the provided gasket and three sealing strips. The sealing strips must be placed along the sides and front of the nozzle to ensure airtightness. Installers should verify that the nozzle is level and that all sealing surfaces are free of debris before tightening. Common mistakes include misalignment or incomplete sealing, which can lead to uneven airflow and reduced boiler performance. The presence of an optional extension block (200 x 200 mm cube) must be confirmed for certain DC50S models.

Compatibility and accessories

The DC0140 is compatible with the following models: DC70GSX (600 mm chamber), DC50S (from 1.1.2010 to 31.3.2018), DC40SE, DC60GSX, GSX60, and GSX70 (600 mm chamber). For DC50S models produced before 1.1.2010, the DC0133 variant is required. For DC50S models after 1.4.2018, the DC0148 variant is used. The package includes a gasket and three sealing strips. An additional extension block (200 x 200 mm) is required for some DC50S models and must be ordered separately.

Technical background for designers

The ceramic construction of the nozzle provides resistance to high temperatures and mechanical stress, making it suitable for long-term exposure to combustion gases. The nozzle integrates directly into the combustion chamber, where it regulates air supply based on boiler load and fuel type. The geometry of the nozzle opening (280 x 45 mm) influences the turbulence and mixing of air with fuel, affecting combustion efficiency. Long-term performance is influenced by correct installation, regular cleaning and the quality of fuel used.

Service and operation

Regular inspection of the sealing strips and gasket is recommended to ensure continued airtightness. Any signs of wear or cracking should be addressed promptly. The ceramic material is durable, but damage due to thermal shock or physical impact may require replacement. During boiler shutdown, the nozzle should be visually inspected for soot buildup or blockage.
