Burning through logs at a high rate 

Stove is making a whistling noise 


  • Stove Whistling can be a sign that a flue stabiiser or flue damper is required. Whistling is a result of the air needed for combustion entering the stove through restricted airways and across sharp or angular edges. It is usually caused by high flue draughts above 20 pa (pascals). Whistling is also more common on stoves with tertiary air inlets.
  • If your stove is Whistling we would recommend checking your flue draught.

Stove is making a clicking noise 


  • It is normal for a woodburning stove to make some noises when firing. It is due to the metal component expanding and contracting when heating up. This is very common in small 5kw woodburners. 
Excessive Smoke 
  • Persistent fume emission is potentially dangerous and must not be tolerated. If fume emission persists: Open doors and windows to ventilate the room. Leave the room. Seek Expert Advice if necessary. 
  • You may have a cold stove and cold chimney which may need a small fire before lighting. Read more on cold chimneys.
  • Burning Wet / unseasoned logs can cause a smoky burn and smell. Read more on burning seasoned logs
  • Poor flue draught. Check your flue draught 
  • Baffle installed incorrectly or damaged - check your stove manual on correct position of your baffle
  • Refuelling at the wrong time- Fuel should only be added when flames are not present, onto hot embers. When you’re finished using the stove and the fire is out, don’t be tempted to shut down the air controls.Leaving the levers fully open will allow air to flow into the stove and through the flue to help prevent the cold air blockage occurring.
  • Incorrect operation of the air controls. Check your stove manual on air control operation when lighting and refuelling.
