Combustion air supply (additional heater only)

The intake opening for combustion air must be located so that it cannot
become clogged with dirt. It must not point towards the front of the car.
A combustion air intake line is required.
The extraction point for the combustion air must be located in a cool
(temperature ≤ 20 °C) place where it is protected from splashing water
and above the vehicle's water clearance level.
Under no circumstances may the combustion air be taken from areas
occupied by people. A ventilation opening measuring at least 3 cm
required if the heater is installed in an enclosed box.
If the heater is installed in a general installation space near the vehicle's
fuel tank, the combustion air must be taken in from the outside and the
exhaust fumes discharged into the atmosphere. The openings must be
splash-proof.
9.1. Air intake silencer
The air intake silencer must be installed in a position between 0° and 90°
pointing downwards.
Installation instructions
Connect the slotted side (approx. 18 mm) of the combustion air intake
line, max. 400 mm long, to the air intake port on the heater and secure
it with the hose clip supplied.
Turn the air intake silencer as far as possible into the unslotted end of
the air intake line (it does not need any additional fastening with a hose
clip).
IMPORTANT
Ensure that it is an adequate distance from the exhaust system.
