Side Seal for Hearth DC0163, Atmos S0953

Product detailed description

Side seals for hearths are essential components in solid fuel boilers, ensuring airtight combustion chambers and maintaining thermal efficiency. These seals are commonly used in residential and commercial heating systems where Atmos models are installed. Installers and service technicians frequently replace these seals during routine maintenance or after boiler modifications. The seal must be selected according to the specific model and chamber dimensions to ensure proper function and safety.

Correct installation of the side seal is crucial for the boiler’s performance and longevity. It prevents heat loss and ensures that combustion gases remain contained within the chamber. This product is intended for use with the upper combustion chamber of selected Atmos models and should be installed in accordance with the manufacturer’s guidelines.

Technical parameters

Installation and connection

Installation of the side seal involves removing the old seal and fitting the new sealing cords into the designated grooves of the upper combustion chamber. The cords must be cut to the correct length and positioned carefully to avoid gaps. Installers should verify that all sealing surfaces are clean and free from debris before fitting. Common mistakes include incorrect cord placement or using mismatched dimensions, which can compromise the seal’s effectiveness. It is important to follow the manufacturer’s instructions to ensure a secure fit and optimal performance.

Compatibility and accessories

This side seal is specifically designed for use with the following Atmos models: DC40GS, DC40GD, DC50GD, GS40, DC40GSE, and DC50GSE. It is intended for the upper combustion chamber and should be used in conjunction with the ceramic hearth. Additional materials such as refractory cement or high-temperature adhesive may be required for a secure fit, depending on the installation. Related products include the Side Hearth Atmos DC0163 and Tile Adhesive in Tube, which may be useful for sealing and finishing the installation.

Technical background for designers

The side seal functions by creating an airtight barrier between the ceramic hearth and the combustion chamber. The sealing cords are made from high-temperature resistant materials to withstand the thermal stresses of the combustion process. The design of the seal ensures that it remains stable under operating conditions and contributes to the overall efficiency of the boiler. The dimensions of the sealing cords are critical for proper integration into the system and must be selected based on the specific model and chamber geometry.

Service and operation

Regular inspection of the side seal is recommended to ensure continued performance. Signs of wear, such as cracking or deformation, should be addressed promptly to prevent heat loss or combustion inefficiencies. During service, the seal should be removed and inspected for damage. If any deterioration is observed, the seal should be replaced with a new set of sealing cords. No specific service intervals are provided in the brief, but maintenance should be performed as part of routine boiler servicing.
