Thank you for purchasing the MV Airo 2 Air heater.
This instrucon book describes the structures,
working principles, installaon and operaon of the
MV Airo 2. For correct use of the heater, please read
this instrucon book carefully before installaon and
use. The instrucon book should be saved in a
convenient place for reference later.
Introducon
Comply with the operaon manual for installaon
and use, to ensure prolonged and reliable operaon.
The main equipment of the MV Airo 2 air heater
(hereinaer referred to as ‘the heater’) is a small fuel
furnace controlled by a single-chip micro-processor.
Its furnace body (the heat exchanger) is located in the
hood shaped case, which serves as an independent
air passage. Cold air is drawn into the air passage by
the fan and blown out when it becomes hot.
The heat can be supplied by the heater to the driver’s
cab and passenger’s compartment independently
from the engine. The schemac diagram is shown in
Fig I.
The heater is fully automacally controlled. It
features a compact structure, easy installaon, low
running costs, easy maintenance and is safe and
reliable.
Aenon
This instrucon book is subject to revision
without noce, but the instrucon book is in
conformity to the purchased product.
Our effort is to explain all quesons you may
have. If you have any doubts or find anything
incorrect in this manual, please contact us
directly.
Check the heater for any damage when
unpacking and contact the dealer immediately if
anything is found.
If any troubles arise during applicaon, please
contact MV Heang or other customer service
staons authorized by this company. We shall do
our best to provide service to you.

The structure of the main heater is shown in Fig. III
Case Assembly
Figure IV
Page 4 of 21
The heat exchanger is made of die-cast aluminium, with
radiang fins around the rear. The combuson chamber
fits inside the inner cavity of the heat exchanger. The
burner assembly and glow pin, fit into the end of the
combuson chamber. Fuel comes to the burner
assembly through the fuel pipe and is ignited by the glow
pin. The flame is passed up the combuson chamber and
returns between the inner walls of the heat exchanger
and discharged through the exhaust outlet vent to the
outside of the vehicle or boat.
The air supporng combuson of the furnace,
comes from the combuson air inlet port and
is sent down the combuson pipe by the
combuson supporng air blades of the fan
motor.

Aenon:
Do not mount the heater near any flammable sources
Do not install the heater in closed spaces without venlaon
Do not place the heater near anything that can cause a blockage
Do not mount the heater near any water sources and protect it from any splashing
Figure V shows the diagram for
installaon. The posion and
ways of fixing of various parts
may vary from one vehicle/boat
to another, but the general
principles remain the same.

For the ease of servicing, fault finding and air flow it’s recommended that the main body is placed in an area with
easy access. Figure VI shows the minimum distances required.
Installaon of the Main Heater Body
Choose a flat installaon surface, any undulaons could cause the case to twist
and will not ensure an even mount. Make sure there are no foreign bodies
between the boom of the heater and the installaon surface itself. This will
ensure a good seal between the two. File down any drill holes to again ensure an
even mounng surface. Tighten the M6 bolts provided to a torque seng of
6Nm+1Nm.
Figure VII shows the posion of the installaon holes. If the installaon area is
less than 1.5mm thick a mounng plate will be required (Figure VIII).

Aer installaon, make sure there is no fricon
between the fan and other nearby parts to ensure
smooth operaon and make sure the heater label is
clearly visible for ease of maintenance in the future.
Avoid re-entering of the supplied hot air into the inlet
port (as shown in Figure X). If no inlet pipe is
required, make sure the grill is installed at the inlet
port instead (Figure IV no. 17).
The direcon of the heater for installaon is shown in
figure IX. Ensure you do not exceed the inclinaon
angle or normal operaon will be affected.
Make sure that the hot air outlet does not exit onto
any parts affected by heat and that it isn’t directed
toward the flow of anything that can cause a
blockage, near splashing water or near the vehicles
exhaust.

Figure XI Figure XII
Addional Ducng (Oponal)
The combuson air inlet pipe sucks in fresh air from
outside of the vehicle and the exhaust discharges
fumes outside of the vehicle. Measures must be
taken to avoid the fumes from re-entering the
vehicle.
The pipes should exit at the boom of the vehicle,
ensuring that the openings are far enough away from
any splashing water or dirt that can clog them. Figure
XIII shows the right and wrong way to install the
pipework.

A & B – Correct C & D - Wrong
Only use the inlet pipe and exhaust provided with the
kit for installaon. The exhaust pipe is made of
corrugated stainless steel while the combuson pipe
is aluminium covered in paper and plasc. Do not
confuse the two. Use the supplied clamps to fix them
securely to the combuson air inlet and the exhaust
outlet on the heater. The protecve end cap on the
outlet of the combuson air pipe and exhaust pipe
should be kept in good condion. Do not damage or
remove them.
Both the combuson air pipe and exhaust pipe should
come downward from the heater and face opposite to
the vehicle’s direcon of travel. If the pipe cannot
avoid a curve, make sure the radius is no smaller than
50mm and the sum of all curves does not exceed
270˚. Figure XIII shows the right and wrong way to
install the combuson air intake. Note that it is the
same for the exhaust too.

When the heater is operang, the exhaust will get
hot, so make sure it is installed away from any parts
that could get damaged by high temperatures. The
exhaust vent should also point downward to the road
surface with an angle of 90˚±10˚ This is best achieved
by fixing a clamp 150mm from the pipe end.
Any exposed exhaust should be covered with a heat
shield to prevent scalding.

Where possible the fuel line is ideally placed uphill to
the fuel pump to ensure ideal bleeding of the fuel
line.
Always fit the fuel pump on the an-vibraon mount
securely onto the vehicle. Ensure the outlet of the
fuel pump lts upward. The correct angle is shown in
Figure XVII.
