It is important to select the right chimney to ensure the correct function of your wood-burning stove. If there is insufficient "airflow" in your chimney, this can result in smoke blowback and poor combustion. This will affect the functionality of your stove, your fuel economy and the environment.
For roof angles of 0 to 20 degrees, the mouth of the chimney must be at least 40 cm above the spine of the roof or at least one meter away from the roof surface.
For roof angles exceeding 20 degrees, the mouth of the chimney must be at least 40 cm above the spine of the roof or at a horizontal distance of least 2.30 m from the roof surface.
All new chimneys must be at least 1 m above the outer edge of ventilation intakes, windows or doors within a radius of 15 m from the chimney.
