The min. gradients are:
horizontal flue pipe: min. 3° (min. 5.5 cm per metre)
external wall duct: min. 1° (min. 2.0 cm per metre)
Shortening of the pipes
All simple and concentric pipes may be shortened. After cutting, the ends
of the pipes have to be thoroughly de-burred. When a concentric pipe is
shortened, a piece of pipe at least 6 cm long must be cut off the outer
pipe. The spring washer for centring the inner pipe becomes obsolete.
1. The pipes and formed pieces have to be fitted together up to the
connector basis. Only the original profile seals of the building kit or
the original spare seals may be used between the individual ele
ments. Before assembly, the seals must be treated with the silicone
paste which is part of the scope of delivery. When routing the pipes
care must be taken that the pipes are installed in line and without
tension. In this way leaking of the seals is prevented.
2. For fastening the support rail in the opposite wall of the shaft open
ing, a bore hole (Ø=10 mm) must be provided on the level fo the
opening edge. Then the pin of the support rail has to be hammered
into the bore hole.
3. The flue pipe is lowered from the top into the shaft. For this, connect
a rope to the support leg and insert the pipes, section by section,
from the top. To prevent the components sliding apart during assem
bly, the rope must be kept on tension until the final assembly of the
flue pipe. If spacers are necessary, these have to be fitted to the
duct at least every 2 m.
4. Cant the spacers at a right angle and align centric in the shaft. Pipes
and formed parts are to be installed in such a way that the connec
tors are arranged counter to the flow direction of the condensed wa
ter.
After the pipes have been inserted, place the support leg in the support rail
and align (flush and without tension). The shaft cover at the chimney head
must be assembled in such a way that no rainfall can get into the space
between flue pipe and shaft and the air for back ventilation can flow freely.
