2. Important Safety Instructions
- Always place the fan on a flat, stable surface on top of your stove.
- Ensure the fan is placed at the rear of the stove top, away from the chimney flue, to avoid direct contact with excessively high temperatures.
- The fan operates within a temperature range of approximately 60°C (140°F) to 345°C (653°F). Exceeding 345°C (653°F) can damage the fan.
- Do not handle the fan directly when it is hot. Always use gloves or wait for it to cool down.
- Keep children and pets away from the fan during operation.
- Never immerse the fan in water or any other liquid.
- If the fan stops working or shows signs of damage, discontinue use immediately.

4. Setup and Placement
- Unpack the stove fan and ensure all components are intact.
- Place the fan on a smooth, flat surface on the top of your wood stove or fireplace.
- Position the fan towards the back of the stove, ensuring it is not directly in front of the chimney flue or in an area where temperatures exceed 345°C (653°F).
- For optimal performance, place the fan where it can draw cooler air from the back and push warm air forward into the room.
5. Operating Instructions
The MERTTURM stove fan operates automatically based on the heat generated by your stove. No manual intervention or external power source is required.
- Starting Temperature: The fan begins to operate when the stove surface temperature reaches approximately 60°C (140°F).
- Optimal Operation: The fan's speed increases as the stove temperature rises, reaching maximum efficiency between 60°C and 345°C (140°F - 653°F).
- Overheating Protection: If the temperature exceeds 345°C (653°F), the fan's bimetal strip will automatically lift the base to protect internal components.
- Stopping Operation: As the stove cools down, the fan's speed will decrease and eventually stop when the temperature falls below the starting threshold.

6. Maintenance
- Cleaning: Periodically wipe the fan blades and base with a soft, damp cloth once the fan has completely cooled down. Do not use abrasive cleaners.
- Inspection: Regularly check for any signs of damage to the blades or base. Ensure the fan spins freely.
- Storage: When not in use for extended periods, store the fan in a cool, dry place.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Fan does not spin | Stove temperature is too low. | Ensure stove surface temperature is above 60°C (140°F). |
| Fan spins slowly | Stove temperature is not optimal. | Increase stove temperature or reposition the fan to a hotter spot on the stove top (within safe limits). |
| Fan is noisy | Fan blades are dirty or damaged; fan is not level. | Clean blades. Check for damage. Ensure fan is on a flat, stable surface. |
| Fan stops unexpectedly | Stove temperature exceeded 345°C (653°F) and overheating protection activated. | Allow stove to cool down. Reposition fan to a slightly cooler area if possible. |
