Control electronics board for automatic rust cleaning – Attack EK049 (H30806B)

What is that?

The board H30806B, referred to as "Electronics of cleaning of the pellet burner grate EK049", is a specialized control electronics unit for the cleaning mechanism of the Attack EK049 pellet burner. It does not take over the complete burner control, but exclusively controls the processes for the automatic cleaning of the burner grate.

Internally, Attack lists it as a spare part under the aforementioned part number, and it connects the mechanical components of the cleaning process with the main control of the burner.

What is this electronics used for?

The circuit board ensures that the grate is regularly cleaned of ash and slag to guarantee stable combustion and consistent burner performance. It initiates, monitors, and terminates the cleaning sequence according to predefined parameters.

Without this control, the automatic cleaning mechanism cannot work correctly, which can lead to blockages, poor flame formation and increased maintenance.

Features in detail

The electronics control the drive of the cleaning mechanism (motor, slide or movable grate) and regulate the sequence and duration of the movements so that the cleaning is effective and gentle.

It manages cleaning intervals based on operating hours, starts or time specifications, and coordinates the cleaning with the burner output (e.g., briefly reducing the output during cleaning).

In addition, the circuit board monitors end positions, detects blockages or malfunctions and provides feedback to the main control unit to prevent damage or trigger error messages.

Signs of a defect

Typical signs of faulty electronics include: failure of automatic cleaning, unusual noises during the cleaning cycle, repeated error messages or blockages that cannot be explained mechanically.

Other symptoms may include a decrease in combustion performance, increased soot buildup, or more frequent manual cleaning requirements. If such observations occur, the circuit board should be checked as a possible source of the problem.

Compatibility and spare part number

This spare part is specifically designed for the Attack EK049 pellet burner and is listed under part number H30806B. It is not intended as a replacement for the complete burner control unit, but rather as a module for the grate cleaning mechanism.

Installation instructions and safety

Installation should only be carried out with the unit disconnected from the power supply and ideally by a qualified electrician. Before working on the burner: disconnect the main power supply, disconnect the supply cables, and minimize electrostatic risks. Improper installation can cause further damage or compromise operational safety.

When connecting, pay attention to plug connections, polarity and possible pin assignments; if there are any uncertainties, it is recommended to consult the manufacturer or the responsible customer service department.

Maintenance tips

Regular visual inspections for corrosion, loose connections, or foreign objects will extend the service life of the electronics. Carefully clean the area around the control unit of dust and ash without damaging the components.

Error messages or recurring malfunctions should be diagnosed promptly, as timely replacement of the circuit board can prevent major consequential damage and longer downtimes.

Advantages

Targeted control of grate cleaning increases operational reliability, reduces maintenance costs and ensures consistent combustion quality.As a specialized replacement board, the H30806B enables a cost-effective replacement without having to replace the entire burner control system.
