3.3 Installation of the air intake pipe.
The air for combustion must not be taken from the interior, living space, engine
or luggage compartment of the vehicle or vessel. Air should be taken from well-ventilated
areas or from outside of the vehicle or vessel.
The maximum length of the air intake pipe is 2 meters. The air pipe must be as short as
possible (cut to the minimal length if required)
Make sure FLOW 14D air intake does not touch any rainwater or dirt blockage.
The air intake pipe is connected directly to the pipe
of the heater and fastened with a clamp. (Fig.7a).
When laying the air intake pipe, avoid sharp bends
and do not obstruct the opening of the air intake pipe
with foreign objects. Make sure the opening is pointing
downwards (see Fig. 8).
If that is not possible, a Ø3mm hole needs to be drilled at the lowest point of the pipe.
The correct installation of the exhaust and air intake pipes is when they are on the same side
(Fig.9a/b). The distance between them should exclude the re-suction of exhaust gases
through the air intake (at least 20 cm).
