Types of air ducts and foundations for chimneys

Nuances chimney installation on their own.

All types of chimney systems are distinguished by two main features:

first - the material from which the chimney;

second - mounting method of the whole structure, as the foundation for chimneys.

By Material chimneys are classified into two groups:

• brick construction;
• metal chimneys.

By way of installation on the foundation of the smoke removal system is divided into three main categories:

• Shaft - chimneys installed on the base, which is located on top of the unit, as it must be mounted on it and the pipe itself crosses the ceiling;
• radical - chimney and hearth have a common foundation;
• facade - chimney installation of this type involves the removal of pipes outside the house, in his facade.

Such systems smoke taps help to solve the problem is not only clean air in the room, but also allow consumers to choose the optimal design for individual design solutions.

Building chimney does not imply knowledge of specific processes, and can be done with his own hands, and the average home owner's backyard.But the application of the simplest technologies should take into account certain nuances that affect the quality of the entire structure.When mounting the fume collection system should be aware that:

• chimney height should be a minimum of 0.5 m above the ridge on the roof.With flat roof must be optimized to reduce the distance between the chimney and the top of the roof, it will significantly reduce the height of the tube;
• when installing a fireplace or furnace chimney should take into account the fact that the temperature of the smoke passing through the structure can reach 800 ° C in.Any material after such exposure to heat for a long time can lose their strength characteristics, and burn.Therefore chimney construction, especially metal, must be collapsible to be able to replace the lower portion.However, if you acquired a chimney made with inner surface lining of the chimney technology, you do not need to worry as the metal.This bothered the producers, only the price of the improved device is higher than the average.
• chimney device must be designed according to the principle - "one heat source - a chimney."You can not connect a second seat to the already existing right, as this will greatly reduce cravings and in one and in the other channels.
• there is typical minimum chimney dimensions - 140mm × 270mm.Of course, these parameters may be increased, but it is impossible to reduce the stated dimensions as the chimney just will not be thrust.

Set the foundation for the chimney.

Collect the chimney design should start with the foundation.The basis for the flue pipe can be:

• concrete slab, thickness not less than 10 cm;
• brick foundation, which uses a solid single-layer process masonry.

Note - the foundation under the brick chimney inside the building can be below floor level to 50cm.When the chimney is taken out of the wall of a house, the foundation of its foundation must be at the foundation of the house.
