Chimneys for fireplaces.
In each person, the fireplace causes associations of heat and comfort, with a pleasant crackling of logs into long winter evenings. It will be possible to enjoy such comfort when a chimney, which is a direct channel, which should not have narrowing in the direction of the chimney, is qualitatively installed. On the chimney channel, combustion products are displayed into the atmosphere. There are no smoke channels in the fireplace, unlike ordinary furnaces.
