9 Combustion air supply
The air inlet must be so positioned or guarded that blocking by rubbish or
luggage is unlikely. (Requirement from 2001/56/EC, Appendix VII, Point
2.5.2. and ECE R122, Point 5.3.5.2.).
9.1. Combustion air pipe
The intake opening for combustion air must be located so that it cannot
become clogged with dirt. It must not point in the direction of travel.
An intake line is required for combustion air.
The withdrawal point for the combustion air must be located in a cool place
where it is protected from splashing water and above the fording line of the
vehicle.
A ventilation opening measuring at least 3 cm
2
is required if the intake
opening is installed in an enclosed installation space.
9.2. Intake silencer
The air intake silencer must be installed in a position between 0° and 90°
pointing downwards.

9.3. Recommendations for installation
Screw a combustion-air intake pipe with a maximum length of 400 mm
onto the combustion-air intake connection piece of the heater.
Screw the combustion-air intake silencer as far as possible into the combus-
tion-air intake pipe.
Leaks can result in a higher noise level. Ensure an adequate dis-
tance from the exhaust system to prevent the intake of exhaust
gas!
Depending on the installation, the combustion air intake silencer can be lo-
cated in a suitable location and secured with the included mounting clip or
other installation materials which utilise the latest technology.
