Installation of the air intake pipe
.
The air for combustion must not be taken
from the cabin, engine or luggage compartment of
the vessel
. Air should be taken from well-ventilated
areas or from outside of the vessel.
The maximum length of the air intake pipe is 2
meters. The air pipe must be as short as possible (cut
to the necessary length). When laying the air duct,
avoid sharp bends and do not obstruct the opening of
the air intake pipe with foreign objects.
The air intake pipe is connected directly to the
pipe of the heater and fastened with a clamp. (Fig.7).

the heater
The correct installation of the exhaust and air intake pipes is when they are on the same
side (Fig.8). The distance between them should exclude re-suction of exhaust gases through
the air intake (at least 20 cm).
