Disregarding this recommendation can lead to the opposite movement of
the flame towards the air pump fan, resulting in the melting of the air pump
fan, and to the burning of the heater.
In cases when the intake of clean air cannot be ensured, such as off-road
and special purpose vehicles, please mount the dedicated AUTOTERM air
filter (assy.2684)
3.3.1 Installation of the air intake pipe on maritime vessels
Air intake from well-ventilated areas
Ambient pressure and sufficient ventilation using outside air must be present in the
air intake zone. Increased or reduced pressure in the air intake zones is not permitted. It
is recommended that the air duct is attached along the entire length of the vessel's hull of
using plastic clamps when possible. Put a cap on the end of the air duct to protect it from
drawing in foreign objects.
Air intake from outside of the vessel.
An air intake pipe (Fig.10) should be used to take in the air from outside. Make an
opening of Ø26+1 mm in the board of the vessel to install it. Install a rubber gasket between
the flange of the air intake pipe and the hull of the vessel. Attach the air duct using three
bolts as shown in Fig.10. Attach the air duct to the air intake pipe using the clamp.
It is recommended to attach the air duct along its entire length to the hull of the vessel
using plastic tie straps when possible. Make a 3mm opening in the bottom point of the air
duct to drain condensation or any water that has penetrated the air intake pipe.
Do not place the intake opening of the air intake pipe in front of the incoming
air flow of the moving vessel.
