10 Combustion air inlet and exhaust lines

Both lines are to be installed falling away from the heater. If this is not pos-

sible, a condensate drain hole with a diameter of 4 mm must be made at

its lowest point.

The lines must not point to the front of the vehicle.

Fig. 20: The lines must not end pointing towards the front of the

vehicle

The lines must be located so that they cannot become clogged with dirt.

If the exhaust pipe ends is other than as shown in the Figure 22 it will pose

a fire risk.

Length of the combustion air inlet and exhaust lines in total:

with silencer: max. 2.0 m

without silencer: max. 5.0 m

NOTE:

If the exhaust line is over 2 m in length the lines must be insulated (to pre-

vent falling below the dewpoint)

Internal diameter of the lines:

Combustion air line: 22 mm

Exhaust line (metal): 22 mm

Minimum bending radius: 50 mm

Total bends:

Combustion air line: max. 270°

Exhaust line: max. 270°
