Internal rosettes KABOLA

Internal rosettes. Made of A4 stainless steel (AISI 316), wall thickness 1 mm.
The flanges are conceptualized so that the flue pipe (Art-Nr. 4310-...) can be stuck through;
thus the pipe is well insulated from the deck, there is no heat bridge to the deck.
On the outside, attach either a double-walled flue pipe (4314-...) or a long (double-walled) exhaust hood from KABOLA (4313-590...).
