1. Einleitung
This user manual provides essential information for the safe and efficient installation, operation, and maintenance of your Prity WD W29 wood boiler stove. Please read these instructions carefully before using the appliance and retain them for future reference. This stove is designed for residential premises using solid fuel, wood briquettes, or dry wood.
2. Sicherheitshinweise
Always prioritize safety when operating any wood-burning appliance. Failure to follow these safety guidelines can result in property damage, injury, or death.
2.1 Allgemeine Sicherheitsvorkehrungen
- Sorgen Sie für eine ausreichende Belüftung des Raumes, in dem der Ofen aufgestellt ist.
- Never use flammable liquids to start or rekindle a fire.
- Halten Sie Kinder und Haustiere von den heißen Oberflächen des Herdes fern.
- Only burn approved fuels (dry wood, wood briquettes). Do not burn trash, plastics, or treated wood.
- Regularly inspect the chimney and flue pipe for blockages or damage.
- Have the stove and chimney inspected and cleaned by a qualified professional annually.
- Installieren Sie Rauch- und Kohlenmonoxidmelder in Ihrem Haus.
2.2 Clearances to Combustible Materials
Um Brandgefahren vorzubeugen, sind folgende Mindestabstände zu brennbaren Materialien einzuhalten:
- Hinteren: 40 cm
- Linke Seite: 40 cm
- Rechte Seite: 40 cm
- Front: 80 cm (from the radiant heat area)
- Boden: 0 cm (if installed on a non-combustible hearth)
Note: These distances are minimum requirements. Always consult local building codes and regulations, which may require greater clearances.

3. Einrichtung und Installation
Installation of this appliance must be performed by a qualified professional in accordance with all local and national building and fire codes.
3.1 Auspacken und Prüfen
- Nehmen Sie den Herd vorsichtig aus der Verpackung.
- Prüfen Sie den Herd auf Transportschäden. Melden Sie jegliche Schäden unverzüglich Ihrem Lieferanten.
- Stellen Sie sicher, dass alle in der Packliste aufgeführten Komponenten vorhanden sind.
3.2 Standort- und Feuerstellenanforderungen
- The stove must be placed on a non-combustible hearth that extends beyond the stove's footprint according to local regulations and the specified clearances.
- Ensure the floor can support the weight of the stove. The stove weighs approximately 10 kg (Note: This weight from specifications seems incorrect for a boiler stove. Please verify actual weight with supplier or manufacturer before installation).
- Maintain required clearances to walls and other combustible materials as detailed in Section 2.2.
3.3 Abgasanschluss
- Connect the stove to a suitable chimney or flue system using a flue pipe with a diameter of 150 mm.
- Stellen Sie sicher, dass alle Abgasrohrverbindungen ordnungsgemäß abgedichtet sind, um Rauchaustritt zu verhindern.
- The chimney must be in good condition, free of obstructions, and capable of providing adequate draft.

4. Bedienungsanleitung
Follow these steps for safe and efficient operation of your wood boiler stove.
4.1 Kraftstoffart
Only use dry, seasoned wood or approved wood briquettes. The moisture content of wood should be below 20% for optimal efficiency and reduced emissions. Burning wet wood leads to creosote buildup and reduced heat output.
4.2 Ein Feuer entzünden
- Open all air inlets (primary and secondary air controls) fully.
- Place crumpled newspaper or firelighters at the bottom of the combustion chamber.
- Stapeln Sie kleine Anzündholzstücke auf das Zeitungspapier/die Anzündwürfel.
- Place a few small logs on top of the kindling.
- Ignite the newspaper/firelighters.
- Close the combustion chamber door once the kindling is burning steadily.
- Allow the fire to establish for 10-15 minutes with air controls fully open.

4.3 Adding Fuel and Air Control
- Before opening the combustion chamber door, open the air controls fully for a few moments to prevent smoke spillage.
- Carefully open the door and add more logs as needed.
- Close the door and adjust the air controls to achieve the desired burn rate and heat output. Reduce primary air for a slower burn, and secondary air for cleaner combustion.
5. Wartung
Regular maintenance ensures the longevity and efficient operation of your stove.
5.1 Ascheentfernung
- Remove ash from the ash pan regularly, typically daily or every few days depending on usage.
- Ensure the fire is completely out and the ashes are cool before removal.
- Use a metal container with a tight-fitting lid for ash disposal. Store the container away from combustible materials.

5.2 Cleaning the Combustion Chamber and Flue
- Periodically clean the interior of the combustion chamber to remove any creosote buildup.
- The second upper door facilitates easy cleaning of the internal components.
- The flue pipe and chimney should be inspected and cleaned by a certified chimney sweep at least once a year, or more frequently if burning resinous wood.
5.3 Allgemeine Inspektion
- Check door seals for wear and tear. Replace if necessary to maintain airtightness.
- Inspect glass for cracks or damage.
- Ensure all moving parts (air controls, door hinges) operate smoothly.
6. Fehlerbehebung
This section addresses common issues you might encounter with your wood boiler stove.
| Problem | Mögliche Ursache | Lösung |
|---|---|---|
| Rauch dringt in den Raum | Poor chimney draft, blocked flue, door opened too quickly, wet wood. | Check chimney for blockages. Ensure air controls are open before opening door. Use dry wood. Consult a chimney sweep. |
| Geringe Wärmeabgabe | Wet wood, insufficient air supply, small fire, creosote buildup. | Use dry wood. Open air controls. Build a larger fire. Clean flue and stove. |
| Übermäßige Verbrennungsrate | Too much air, door seal leakage. | Close air controls. Inspect and replace door seals if necessary. |
| Glas wird schnell schwarz | Feuchtes Holz, unzureichende Sekundärluftzufuhr, niedrige Verbrennungstemperatur. | Use dry wood. Ensure secondary air is open. Maintain a hotter fire. |
