1. Introduction
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. Safety Information
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 General Safety Precautions
- Ensure proper ventilation in the room where the stove is installed.
- Never use flammable liquids to start or rekindle a fire.
- Keep children and pets away from the hot surfaces of the stove.
- 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.
- Install smoke and carbon monoxide detectors in your home.
2.2 Clearances to Combustible Materials
Maintain the following minimum distances from combustible materials to prevent fire hazards:
- Rear: 40 cm
- Left Side: 40 cm
- Right Side: 40 cm
- Front: 80 cm (from the radiant heat area)
- Floor: 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. Setup and 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 Unpacking and Inspection
- Carefully remove the stove from its packaging.
- Inspect the stove for any signs of damage during transit. Report any damage to your supplier immediately.
- Ensure all components listed in the packing list are present.
3.2 Location and Hearth Requirements
- 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 Flue Connection
- Connect the stove to a suitable chimney or flue system using a flue pipe with a diameter of 150 mm.
- Ensure all flue pipe connections are sealed properly to prevent smoke leakage.
- The chimney must be in good condition, free of obstructions, and capable of providing adequate draft.

4. Operating Instructions
Follow these steps for safe and efficient operation of your wood boiler stove.
4.1 Fuel Type
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 Starting a Fire
- Open all air inlets (primary and secondary air controls) fully.
- Place crumpled newspaper or firelighters at the bottom of the combustion chamber.
- Stack small pieces of kindling on top of the newspaper/firelighters.
- 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. Maintenance
Regular maintenance ensures the longevity and efficient operation of your stove.
5.1 Ash Removal
- 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 General Inspection
- 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. Troubleshooting
This section addresses common issues you might encounter with your wood boiler stove.
| Problem | Possible Cause | Solution |
|---|---|---|
| Smoke entering the room | 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. |
| Low heat output | Wet wood, insufficient air supply, small fire, creosote buildup. | Use dry wood. Open air controls. Build a larger fire. Clean flue and stove. |
| Excessive burn rate | Too much air, door seal leakage. | Close air controls. Inspect and replace door seals if necessary. |
| Glass blackens quickly | Wet wood, insufficient secondary air, low burning temperature. | Use dry wood. Ensure secondary air is open. Maintain a hotter fire. |
