A chimney over 4 meters high will ensure good draft.

A natural draft ventilation system removes air from the room where the fireplace is located, and the chimney system is responsible for removing combustion products from the hearth. By the way, the ventilation and chimney ducts must be vertical, a slight slope is allowed, but without ledges. The inner surface of the chimney must be smooth and of the same cross-section. If you design and install chimneys and ventilation correctly, then thanks to this, the room will always have optimal air exchange and the possibility of backdraft in the ventilation ducts will be eliminated. Also, there will be no smoke and carbon monoxide in the living room with a fireplace. It is allowed to place a single block in the ventilation and chimney ducts, separating them by chinese overseas british data with partitions (hermetically). It is recommended to place the ventilation pipe near the chimney. There are no strict requirements here.

A chimney rising above the tree crowns and neighboring high-rises, with thermal insulation, which in turn maintains a high temperature inside the pipe, will ensure the removal of combustion products under different weather conditions. The height of the chimney head of the fireplace should be higher than the outlet of the ventilated channel pipe.

The ventilation duct can pass a limited amount of air, which depends on the cross-section of the pipe and the speed at which the air flow moves. The quality of natural draft may deteriorate due to a narrowed cross-section of the duct, clogging inside, unevenness of the inner surface of the pipe and a complex shape of the ducts - these are the main factors that affect the draft. And also: air flows that pass through the duct create noise. Strong draft (ventilation through the chimney) is always accompanied by a hum in the chimney. In order to reduce the hum in the chimney, it is necessary to choose the optimal cross-section of the duct and thus maintain a low air flow speed.

Checking ventilation and chimneys should be carried out at a strictly defined time, guided by established standards and common sense, + cleaning them if necessary. As a rule, chimneys are checked quarterly before the start of the heating season, and ventilation ducts are sufficiently checked once a year.
