Connection to the chimney must be made with a pipe at least 150mm, 180mm or 200mm in diameter, depending on replace

type. The stub pipe connection and all other connections to the chimney need to be sealed tight. A special heat resistant paste or

heat resistant modelling glue need to be used here. It is recommended to set the angle of the connecting elbow to be no more than

45° (this prevents excess soot buildup in the connector) and to add a revision door in it (see connection design). Fireplace inserts

with stub pipes less than or equal to 200mm require a minimum chimney surface of 4 dm² (like. 20 cm x 20 cm). Its diameter must

be consistent on its entire length. A too big diameter can be too hard to heat and can lead to disruptions in stove functionality.

The chimney cannot have more than two slopes, and their angles cannot exceed 45° for chimneys up to 5m tall and 20° for taller

Chimneys should be located in the walls between the heated rooms. When the chimney is located in the wall of the building,

perform the isolation of a material resistant to high temperatures. Its absence may result in lowering the temperature of the

exhaust gases and loss the ue draft. Diameter of the ue should not be less than the diameter of duct into the chimney. If the ue

outlet exhaust gas damper is installed, it is in the closed position it should have a section which is not obscured by at least 25% of

the diameter of the exhaust duct. Chimneys should be installed above the roof in accordance with the applicable standard.

fresh air intake

If the air supply is insucient to housing such as apartments equipped with mechanical ventilation must take additional fresh

air supply to the re from the outside or in the basement, if it is not heated in the winter. Diameter of air intake should be at least

¼ of the diameter of ue.
