Figure 21: Permissible installation position of
exhaust silencer (any desired flow direction)
8.6.5 Combustion air inlet and exhaust lines
NOTE:
To avoid damage to the fuel pump cable, it must be ensured that the combustion air intake and exhaust lines
are not confused. The exhaust line must be attached to the exhaust outlet fitting.
Length of the combustion air intake and exhaust lines:
with silencer: max. 2.0 m
without silencer: max. 5.0 m
Both lines are to be installed falling away from the heater. If this is not possible, a condensate drain hole with a
diameter of 4 mm must be made at its lowest point or a connection element with a condensate drain must be used.
Internal diameter of the lines:
Combustion air line: 25 mm
Exhaust line: 24 mm
NOTE:
If the exhaust line is 2 m or more, insulated exhaust lines must be used (to prevent the temperature falling
below the dew point).
Minimum bending radius: 50 mm
Total bends:
Combustion air line: max. 270°
Exhaust line: max. 270°
An attachment is required no further than 150 mm from the end of the exhaust pipe to ensure that an angle of 90° ±
10° is achieved.
