Set (2 pieces) distant holder E80 of polypropylene
for tube centering in shaft 3 sets
8 End tube E80 L = 500 mm to top part 80; high grade steel
9 Top part 80 for chimney end for back ventilation with shaft
cover 400 x 400 mm, clamp tape and seal ring
To determine the total length of flue gas pipe and com -
bustion air duct, the total lengths can be obtained from
the diagrams and calculated for the simple chimney in-
stallation. For the remaining formpieces which have to be
installed, the lengths to be removed must be read off from
the table.
Sizing basis
The following diagrams were computed assuming a geo-
graphic altitude of 1000 m above sea level.
