FIRING PROBLEMS AND SOLUTIONS
Poor draught
• The connection to the chimney stack has not been sealed properly. Ask the sweep to check that the joint between the
stove and the chimney is completely tight.
• The flue is sooted up. Clean the flue and firebox.
• The chimney is too short, has too large a cross-section or is blocked with a bird’s nest. Contact your chimneysweep
or dealer for guidance.
• Negative pressure in the building. Open a window or fit a valve in the outside wall close to the stove.
The wood has excessive moisture content or is too cold. Use only dry wood with a moisture content of 20%.
Too much draught
• The seal on the door is worn. Check the seal and replace if worn.
• The chimney is too tall. Contact your chimneysweep or dealer for guidance.
The glass is sooted up
• The wood is too damp. Use only dry wood with a moisture content of 20%.
• The throttle valve is closed too far. Open the throttle valve to let in more air for combustion.
The glass turns white
• Poor combustion. Follow the instructions on correct firing in this manual.
• Poor quality fuel. Do not use scrap, milled or impregnated wood, plastic laminate,
plywood etc. Always use clean and dry fuel.
Smoke build-up in the room when you open the fire door
• Opening the fire door too quickly will cause pressure equalisation in the firebox. Open the door slowly.
• Poor draught in the chimney. Contact your chimneysweep or dealer to check the height of the chimney
relative to the draught that it needs.
• Excessive negative pressure in the building. Open the supply valve or a window to bring oxygen into the building.
White smoke
• Combustion temperature is too low. Increase the air supply.
• The wood is damp and contains water vapour. Always use clean and dry fuel.
Black or dark grey smoke
• Incomplete combustion. Increase the air supply.
