When moving away from

The minimum elevation of the pipe, which goes at the highest point of the roof or in the area up to 150 cm, should be at least 0.5 m. When moving away from the center, the following principle should be observed. Imagine a conditional line passing to an angle of 100 from the skate to the horizon. So, the top of the chimney, located from the highest point at a distance of 3 m or more, should be not lower than this level. To ensure reliable traction, the total length of the pipe is 5 m from the level of the grate. The section depends on the power of heating devices.
