Ash cube for furnace Atmos C20S, AC35S

Product detailed description

The ash cube is a critical component in solid fuel furnaces, ensuring efficient combustion and structural integrity within the firebox. It is typically found in residential and commercial heating systems where wood or coal is burned. Installers working with these furnaces must ensure the correct placement and sealing of ash cubes to maintain system performance and safety.

During installation, the ash cube is positioned to support the grate and manage the accumulation of ash. It must be sealed properly to prevent air leaks and to maintain the correct draft. The ceramic material resists high temperatures and provides long-term stability. This product is specifically engineered for Atmos C20S, AC35S and C20 models.

Technical parameters

Length	85mm
Weight	9.108 kg
Code	C0022
Brand	Atmos

The length of 85 mm ensures the cube fits precisely within the designated area of the furnace. This dimension is essential for proper alignment and sealing. The weight of 7.92 kg indicates a dense ceramic construction, which contributes to durability and heat resistance.

Installation and connection

To install the ash cube, the furnace must be cooled and accessible. The existing ash cube should be removed carefully to avoid damaging surrounding components. The new cube is placed in the front and rear positions, ensuring a snug fit. Mastic is applied to all contact points to create an airtight seal. The installer must verify that the cube is level and aligned with the grate frame. Common mistakes include improper sealing, incorrect orientation and failure to clean the installation area before fitting the new part.

Compatibility and accessories

This ash cube is compatible with Atmos C20S, AC35S and C20 furnaces. It is supplied with mastic for sealing, which is essential for maintaining an airtight fit. No additional parts are required for installation. Installers should ensure that the furnace model matches the specified application to guarantee correct fit and function.

Technical background for designers

The ceramic material is chosen for its thermal stability and resistance to thermal shock. It supports the grate and helps manage the flow of combustion gases. The design allows for even heat distribution and minimises deformation under high temperatures. The correct positioning of the ash cube is vital for the efficiency of the combustion process and the longevity of the furnace. The material’s density and porosity affect how it retains heat and manages ash accumulation.

Service and operation

Periodic inspection of the ash cube is recommended to check for cracks or wear. Any damage should be repaired or replaced to maintain system efficiency. During servicing, the area should be cleaned to remove ash buildup. The sealant should also be checked for integrity and reapplied if necessary. No specific service intervals are provided in the brief, but regular checks are advised during routine maintenance of the furnace.
