Installation
Preparation for Installation
Proper installation of the furnace dust filter is crucial for its optimal function and your safety. Whether you are installing the filter for your customers or retrofitting it in your own home as a private individual, careful preparation is important in either case. Take enough time for planning to avoid complications later on.
Required Preliminary Checks:
- Checking that the fireplace is in perfect condition
- Confirmation that the system is suitable for retrofitting
- Combustion calculation by the chimney sweep
- Checking the accessibility of the exhaust system
Particularly for private use in your own home, installation should always be carried out in consultation with the responsible chimney sweep. They will not only check the technical suitability, but also carry out the necessary calculations, as the fine dust filter slightly increases the pressure loss in the system. This is particularly relevant during the heating phase, when the necessary negative pressure in the chimney has not yet been fully established.
This ensures that your oven fine dust filter works efficiently and complies with legal requirements – both in your own home and in professional use by specialist companies.
Installation of the Catalytic Converter Unit
The catalytic converter unit is the technical heart of the filter system. It consists of two sponge ceramic catalytic converters with a special precious metal coating and is pre-installed in the flue pipe at the factory.
Important handling rules:
- Always wear protective gloves.
- Never touch catalysts with your bare hands.
- Handle the coating with care
- Use optical positioning aids for correct alignment
The catalyst is relatively insensitive due to the fact that the coating forms a spinel with the substrate. Nevertheless, careful handling is recommended.
Installation in the Flue Gas Piping
Important Assembly Instructions
Diameter compatibility
The filter is designed for flue pipes with an internal diameter of 150 mm as standard. The following rules apply for different diameters:
Smaller diameters:
- Expandable with adapters
- Expansion always in the direction of flow
- Avoid turbulence
Larger diameters:
- Not compatible with this model
- Alternative solutions required
The Bypass Function
The integrated bypass is a critical safety element of the system. It ensures that exhaust gases can be safely discharged even if the filter unit is partially blocked. Correct positioning and regular inspection of the bypass are therefore of utmost importance.
Checkpoints for the bypass:
- Check free flowability before each start-up
- No deposits in the bypass area
- For horizontal installation: bypass positioned at the top
- Regular visual inspection through service hatch
Safety Distances
Maintaining safe distances is required by law and is non-negotiable:
Minimum distances from combustible materials:
- 500 mm in all heat-radiating directions
- For vertical installation: front, rear, left and right
- For horizontal installation: upwards, downwards and to both sides
Wall penetrations must comply with applicable building regulations and fire safety regulations. The expertise of your chimney sweep is essential here.
After Installation
Commissioning Checklist
After completing the installation work, you should systematically check the following points:
Before initial commissioning:
- Check all connections for leaks.
- Verify the correct position of all seals.
- Check that the clamp connections are secure
- Service flap completely closed
- Catalyst and bypass freely flowable
- Safety distances maintained
When firing up for the first time, heat moderately at first and observe the system closely. The catalytic converter requires a minimum temperature of 200°C to be fully effective – this temperature is easily reached during normal operation.
Special Notes for Retrofitting
Special conditions must be observed when retrofitting existing wood-burning stoves. The stove fine dust filter was developed specifically for retrofitting, but is subject to technical limitations.
Technical requirements:
- Nominal heat output: 5–12 kW
- Only simply blocked chimneys
- Exhaust gas temperature: 200–500°C
- Pipe diameter: 150 mm (or adaptable)
The performance limitation is technically justified. If the systems are too small, the exhaust gas temperature may not be sufficient to activate the catalytic converter. If the systems are too large, the exhaust gas volume could exceed the filter capacity and lead to operational malfunctions.
Documentation and Official Approval
The proper installation must be approved by a chimney sweep and documented in a report. The chimney sweep must perform a chimney calculation in advance. This approval not only serves formal requirements, but is also an important component of your legal protection.
Documents to be retained:
- Installation instructions
- Chimney sweep’s inspection report
- Proof of purchase and warranty documents
- Maintenance records
Avoid Common Installation Errors
Practical experience has revealed typical sources of error that you should avoid:
The most common mistakes:
- Inadequate sealing of the joints
- Incorrect positioning during horizontal installation
- Neglecting bypass control
- Failure to maintain safety distances
- Installation without prior chimney sweep inspection
