UCP45S Set for ATMOS A 45 Burner

Product detailed description

Automatic ash removal systems are commonly installed in residential and commercial heating systems using pellet boilers. These systems reduce manual maintenance by transferring combustion residue from the burner chamber to an external container. Installers working with ATMOS pellet boilers must ensure compatibility with the boiler model and existing air supply systems. The UCP45S set is designed for boilers with pneumatic cleaning systems and requires integration with a screw conveyor and control modules.

Technical parameters

Installation and connection

Installation involves connecting the screw conveyor to the combustion chamber and external ash container. The DN 28 connection must be sealed with a gasket to prevent air and ash leakage. The control modules AD03 and AD04 must be wired to the boiler's control system. A 3/4" coupling is used for air supply. Common installation errors include incorrect alignment of the screw conveyor and failure to secure the ash container properly. Ensure the ash container is positioned for easy removal and that the screw conveyor is level to prevent jamming.

Compatibility and accessories

The UCP45S set is compatible with ATMOS models DCxxS, DCxxRS, CxxS(T), ACxxS and DC50S. It requires an external ash container and a compressor with a 5–10 L air tank capable of 5–8 bar pressure. If a separate compressor is not available, the set must be used with an existing system that meets these specifications. The set includes a 1 m air hose, control valve, combustion chamber, and mounting bracket. Additional components such as a metal cover and sealing flap are included for integration with the boiler's existing structure.

Technical background for designers

The UCP45S operates by transferring ash from the combustion chamber to an external container using a screw conveyor. The conveyor is driven by a gear unit and controlled via the AD03 and AD04 modules. The system is constructed from durable materials to withstand high temperatures and abrasive ash. The screw conveyor must be positioned to avoid contact with the combustion chamber walls to prevent wear. The control modules integrate with the boiler's existing control system, allowing for automatic or manual ash removal. The system's efficiency depends on the ash content of the fuel and the frequency of operation intervals, which can be set to 1, 3, 6, 12 or 24 hours.

Service and operation

Regular inspection of the screw conveyor and control modules is necessary to ensure continued operation. When the ash container is full, the system automatically stops and emits an audible signal. To restart the system, the ash container must be emptied and the boiler's switch turned off and on for 5–10 seconds. No specific service intervals are defined in the brief, but periodic checks for wear and alignment are recommended. The system should be disconnected during boiler maintenance to prevent damage to the conveyor or control modules.

Frequently asked questions

Can the UCP45S be used with a boiler that already has an ash container?
Yes, provided the existing container meets the system's pressure and volume requirements. The DN 28 connection must be compatible with the existing container's inlet.

Is it possible to operate the ash removal system manually?
Yes, by turning the boiler's switch off and on. This allows for manual ash removal without changing the automatic settings.

What happens if the ash container is not emptied?
The system will stop automatically and emit an audible signal. Continued operation is not possible until the container is emptied and the system is reset.

Can the system be used with a fuel other than pellets?
Yes, the UCP45S is compatible with wood, wood briquettes and coal. The ash removal intervals can be adjusted based on the fuel's ash content.
