Cut the opening inside the vehicle body (in case the side wall/floor is not thicker than
3 mm) for AIR-8D heater installation as shown on Fig. 3. With the thickness of the vehicle
body (floor) of more than 3mm, installation of the heater requires the following:
1. Cut a rectangular hole in the vehicle body sized 180×95 mm
2. To attach the mounting bracket* to the heater (this bracket can be made of steel
sheet at least 2.5mm thick);
3. Install the exhaust pipe, air intake, and fuel line to the heater and fasten the
whole assembly to the body of the vehicle
*—optional part
3.2 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 necessary length).
It is forbidden to use the heater without
an air intake pipe.
The air intake pipe is connected
directly to the pipe of the heater and
fastened with a clamp. (Fig.4).
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 its opening
is pointing downwards (see Fig. 5). If
that is not possible 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.6a/b). The distance between them should exclude re-suction of exhaust gases
through the air intake (at least 20 cm).
