1.2 Safety Warnings
- Fire Hazard: Always maintain safe distances from combustible materials. Refer to the specifications section for minimum clearances.
- Carbon Monoxide: Ensure proper ventilation and chimney draft to prevent carbon monoxide buildup. Install carbon monoxide detectors.
- Hot Surfaces: The stove surfaces become extremely hot during operation. Use protective gloves when handling parts like the door handle. Keep children and pets away.
- Fuel Type: Only use dry wood as fuel. Do not burn plastics, treated wood, or other unsuitable materials.
- Water System: Ensure the water exchanger system is properly installed, filled, and vented before operating the stove. Overpressure can be dangerous.
2. Setup and Installation
Proper installation is crucial for the safe and efficient operation of your stove. It is highly recommended that installation be performed by a qualified professional.
2.1 Unpacking and Inspection
Carefully unpack the stove and inspect it for any damage that may have occurred during transit. Report any damage to your supplier immediately.
2.2 Location and Clearances
Choose a suitable location on a non-combustible floor. Ensure adequate clearance from walls, furniture, and other combustible materials. Refer to the technical specifications for exact minimum distances.
- Minimum distance to combustible materials:
- Rear: 400 mm
- Side: 400 mm
- Front: 800 mm (within the radiant area of the glass)

2.3 Chimney Connection
Connect the stove to a suitable, properly sized chimney flue. Ensure all connections are sealed and airtight to prevent smoke leakage and ensure proper draft. The chimney must be clean and free of obstructions.

2.4 Water Exchanger Connection
The integrated water exchanger requires connection to your central heating system. This must be done by a certified plumber. Ensure the system includes an expansion tank, circulating pump, safety valve, and pressure gauge. Fill the system with water and bleed all air before operation.

3. Operating Instructions
3.1 Fuel Type
Only use dry, seasoned firewood. Wood moisture content should be 16% ± 4% according to EN 13240:2006. Do not use wet wood, treated wood, coal, or any other combustible materials not specified for this stove.
3.2 Lighting the Stove
- Open the primary air intake fully.
- Place crumpled paper or firelighters at the bottom of the combustion chamber.
- Add a small amount of kindling on top of the paper/firelighters.
- Light the paper/firelighters.
- Once the kindling is burning well, gradually add larger pieces of dry firewood.
- Close the door securely.
3.3 Temperature Control
Adjust the primary and secondary air intakes to control the burn rate and heat output. Closing the air intakes will reduce the burn rate, while opening them will increase it. Avoid over-firing the stove, as this can damage the unit and lead to unsafe conditions.
Note: The manufacturer recommends not overloading the stove with too much wood to avoid high temperatures at the boiler outlet, especially if not connected to a regulated system.
4. Maintenance
Regular maintenance ensures the longevity and safe operation of your Prity K1CPW8 stove.
4.1 Ash Removal
Remove ash regularly from the ash pan located below the cast iron grate. Do not allow ash to build up and block the air intake. Always ensure ashes are cold before disposal.
4.2 Glass Cleaning
The ceramic glass in the combustion chamber may accumulate soot. Clean it when the stove is cold using a specialized glass cleaner for wood stoves or a damp cloth dipped in ash. Avoid abrasive cleaners.
4.3 Chimney and Flue Pipe Cleaning
Have your chimney and flue pipes inspected and cleaned by a certified chimney sweep at least once a year, or more frequently depending on usage. This prevents creosote buildup, which can lead to chimney fires.
4.4 General Inspection
Periodically check all seals, gaskets, and connections for wear and tear. Replace any damaged parts immediately to maintain efficiency and safety.
5. Troubleshooting
This section addresses common issues you might encounter with your stove.
| Problem | Possible Cause | Solution |
|---|---|---|
| Smoke entering the room | Poor chimney draft, blocked flue, downdraft, door not sealed. | Check chimney for blockages, ensure proper ventilation, inspect door seals, pre-heat flue. |
| Stove not heating efficiently | Wet wood, insufficient air supply, excessive ash buildup, chimney issues. | Use dry wood, open air intakes, remove ash, check chimney. |
| Glass blackens quickly | Wet wood, low burning temperature, insufficient air wash. | Use dry wood, increase burn rate, ensure air wash vents are clear. |
| Water system not heating | Air in system, pump malfunction, insufficient heat from stove. | Bleed air from system, check pump, ensure stove is burning at optimal temperature. Consult a plumber. |
