Mark "x" indicates that all components of the flue are sur-
1)
rounded by combustion air and meet higher requirements
for gas tightness.
For type B23, B33 the combustion air is drawn from the
2)
installation room (open flue gas combustion equipment).
In Switzerland, observe the G1 gas guidelines!
3)
For type C, combustion air is drawn through a sealed system
from the outside (room sealed combustion equipment).

A heat exchanger protective function is integrated into the CGB-75/100. This prevents
stresses in the material by limiting the maximum temperature differential between flow
and return. The output is restricted at 28 K and above. If 38 K is nevertheless reached, the
burner shuts down briefly without a fault message. This characteristic must be taken into
account when selecting the components (e.g. pumps, heat exchangers and cylinders).
Excessive flow velocities may lead to erosion.
