Static intermediate support of a Chimney System or a Flue Pipe for the conveying and dispersal in open air of the products resulting from the combustion processes (Gases, Smoke) of natural gas, diesel, wood and mulit-fuel.

For the designation of the Chimney System according to UNI EN 1856-1 the following is allowed:

operation:
- Dry (D)
- Wet (W)

pressures:
- Positive (P1 = 200 Pa)
- Negative (N1 = 40 Pa).

Operating temperatures:
- ≤ 200 ° C with silicone gasket and P1 = 200 Pa

- ≤ 600° C without silicone gasket and N1 = 40 Pa
