FAQ
What kind of fuel can these cast iron log burners be used with?+
These burners are designed primarily for use with seasoned wood logs. Burning other fuels, such as coal or smokeless fuel, is not recommended and may damage the unit. Always adhere to manufacturer’s guidelines regarding fuel type.
How much maintenance do cast iron log burners require?+
Cast iron log burners require regular cleaning after each use to remove ash build-up. Periodically, you'll need to apply a light coat of oil to the exterior surface to prevent rust and maintain the finish – approximately every 6-12 months.
Are cast iron log burners suitable for installation in a chimney?+
Yes, these log burners are designed to be installed in standard brick chimneys that meet current building regulations. Ensure your chimney is swept regularly to prevent blockages and maintain efficient airflow.
What safety precautions should I take when using a cast iron log burner?+
Always ensure adequate ventilation around the burner to prevent carbon monoxide buildup. Keep flammable materials at least 30cm away from the unit, and never leave a burning fire unattended.
How do I clean ash from a cast iron log burner?+
Use a metal brush or rake to remove loose ash regularly. For stubborn residue, you can use a small amount of water and gently scrub with a soft cloth – dry thoroughly afterwards.
Can I paint a cast iron log burner?+
While it's possible to paint a cast iron log burner, it’s strongly advised against using standard paints. Specialist stove enamels are designed to withstand high temperatures and provide optimal protection; otherwise, the paint may blister or peel.

Your chimney must have a flue size compatible with the burner’s output. A minimum flue diameter of 6 inches is recommended, but always consult your local building regulations and a qualified chimney sweep.
Can I use a catalytic converter with this type of log burner?+
No, catalytic converters are not suitable for use with wood-burning stoves or log burners. They are designed to treat exhaust gases from internal combustion engines and will damage the catalyst over time.
What is the typical heat output of a cast iron log burner?+
The heat output varies depending on the size and design of the burner, but generally expect around 3-5kW. Always check the manufacturer’s specifications for precise figures regarding BTU or kilowatt ratings.
