perform connection preferably directly (without other elbows); if it is impossible, use elbows of 45°
-
- connection must be structurally adapted for cleaning and maintenance.
- fulfillment of the proper connection of the fume-extraction system to the smoke uptake has to enable dilatation
- with regards to the flue-gases quantity and temperature, we recommend the fume-extraction system of 160 or 180 mm
(preferably insulated multi-layer stainless-steel or ceramic chimney systems)
