A85 Burner Fan Atmos H0043

Product detailed description

The A85 Burner Fan is a critical component in pellet-burning heating systems, ensuring consistent and efficient combustion. It is commonly used in residential and commercial solid fuel boilers, where precise air flow control is essential for optimal performance. Installers working with Atmos A85 burners will find this fan necessary for system maintenance or replacement after wear or malfunction. The fan integrates with the boiler’s control system to regulate air supply based on load and fuel type.

Correct installation and compatibility are crucial for the fan to function effectively. It is typically mounted within the burner housing and connected to the electrical and air control circuits. The fan must be aligned with the air duct and sealed properly to prevent air leaks, which can affect combustion efficiency and emissions. The fan’s speed sensor provides feedback to the boiler’s control unit, allowing for dynamic air flow adjustments.

Technical parameters

Weight	2.08 kg
Code	H0043
Brand	Atmos

The weight of the fan is 2.08 kg, which is relevant for handling and installation. This parameter does not directly affect performance but is useful for logistics and storage. The fan is designed for use with the Atmos A85 burner model only, and its specifications are tailored to that system’s requirements. The absence of a gasket and starting capacitor in the package means these must be sourced separately to ensure full functionality.

Installation and connection

The fan is installed within the burner housing, typically secured with bolts or screws. The air flap must be aligned with the duct to allow for smooth airflow. The electrical connections should be made to the control unit using the correct wiring diagram. A common mistake is omitting the gasket under the flange, which can lead to air leaks and reduced efficiency. It is also important to verify that the fan is compatible with the existing control system and that the speed sensor is properly connected.

Compatibility and accessories

This fan is specifically designed for the Atmos A85 pellet burner. To complete the installation, the gasket under the fan flange and the starting capacitor must be ordered separately. The gasket is available as 'Gasket under A85 Burner Fan' and the capacitor as 'Capacitor for S0173 Exhaust Fan'. These components are essential for the fan to operate correctly and safely. Installers should ensure that all parts are from the same manufacturer to maintain system integrity and performance.

Technical background for designers

The fan operates by drawing air through the burner and into the combustion chamber, where it supports the burning of pellets. The speed sensor monitors the fan’s operation and sends data to the control unit, which adjusts the air flow accordingly. The fan is constructed from durable materials suitable for high-temperature environments. Its integration into the system depends on the boiler’s control logic and air flow requirements. Factors such as duct design, air resistance, and electrical load can affect the fan’s efficiency and service life.

Service and operation

Regular inspection of the fan’s operation is recommended to ensure it is functioning correctly. The air flap and duct should be checked for blockages or leaks. The speed sensor should be verified for proper signal transmission. The gasket should be inspected for wear or damage, as a faulty seal can lead to air leaks. No specific service intervals are provided in the brief, but routine checks are advisable to maintain system performance.

Frequently asked questions

Can the fan be used with other Atmos burner models?
No, the fan is specifically designed for the Atmos A85 burner model and is not compatible with other models.

Is the gasket included in the fan package?
No, the gasket under the fan flange is not included and must be ordered separately.

What is the purpose of the speed sensor?
The speed sensor monitors the fan’s operation and provides feedback to the control unit, allowing for dynamic air flow adjustments.

Can the fan be installed without the starting capacitor?
No, the starting capacitor is required for the fan to operate correctly and must be ordered separately.
