Technical Description
Introduction .
These Instructions are designed for organizations and
users engaged in the installation of PLANARair heaters. The
document describes basic rules of installation of products in
heated areas, as well as performance testing of the product
after installation. These instructions are used in conjunction
with the Operation Manual.
If a fault occurs due to non-compliance with
the installation instructions and the
information they contain, the manufacturer
bears no responsibility therefore. The same
applies to the repair specialist who does not
have the necessary qualifications, or uses
non-original parts without obtaining the
permission of the manufacturer.
These installation instructions contain the necessary
information and advice on the installation of air heaters
PLANAR.
1 Application / modification .
Application of air heaters.
Air heaters are designed to heat the driver's cabin or
various other interior spaces of limited volume in vehicles
at ambient temperatures up to minus 45°C.
Modification
Heaters run on diesel fuel.
Voltage designations in heater labeling:
«12» designed to operate with power supply voltage of 12V;

3 Installation .
Observe safety requirements during heater
installation.
3.1 Mounting Location
The heater can be mounted both inside and outside the
vehicle.
For outside mounting the heater should be installed in
an area protected from water and dirt. The heater should be
mounted in such a way that it is not exposed to water at
overcoming water obstacles by the vehicle.
Heater dimensions are shown in Figures 5-8.
3.2 Heater Installation
Mounting positions should be in accordance with
those shown in Fig.9-12. The intake of the heater should be
positioned in such a way that, under normal operating
conditions,exhaust gases of the engineor of the heater could
not be sucked into it.
During installation and operation of the heater, intake
and outlet of the heater should be protected against foreign
objects getting into them.
When installing the air ducts to the heater, they should
not have deformations, reducing the flow area of the duct.
The maximum length of the output duct should not exceed
5 meters in total.
When mounting the heater, care should be taken
to ensure that its housing does not have harmful
contact with projecting parts of the floor or other
parts of the cabin.
Installation of air ducts to the air heater
PLANAR-8DM is forbidden
3.3 Mounting Holes.
For heaters PLANAR-2D, PLANAR-4DM2 and
PLANAR-44D, holes in the body of the vehicle should be
made as shown in Fig.12. Heater can be installed using
mounting brackets, see Fig.11 (in that case, longer studs should
be installed in the heater).
For heaters PLANAR-8DM, holes in the body of the
vehicle (with the thickness of the body (floor) of not more than
3mm) should be made as shown in Fig.12.
With the thickness of the vehicle body (floor) of more
than 3мм, installation of the heater requires the following:
1. To make a hole in the form of a rectangle with sides of
180 x 95 mm in the body of the vehicle;
2. To attach a mounting bracket to the heater (this bracket
can be made of steel sheet at least 2.5mm thick, see Fig.12);
3. To attach the exhaust pipe, air intake, and fuel line to
the heater and fasten the whole assembly to the body of
the vehicle

3.4 Heating Air Supply
Heating air is taken from inside the room or from
outside.
Outside air should come from spaces protected from
rain, splashes and dirt, it should not be exposed to water
when the vehicle is crossing puddle, river, etc.
Hot air outlets should be placed in such a way
that air does not come in contact with parts
susceptible to damage by high temperature.
Do not crush or flatten hot air ducting. Duct
diametershouldbe greaterthanor equalto the
diameter of the output fitting of the heater.
Heating ducts should be manufactured only
from materials with heat resistance of at least
130°C.
If the heater is operating with air recirculation, avoid
sucking the flow of heated air into the air intake heater,
Fig.13.
Installation of air ducts to the air heater
PLANAR-8DM is forbidden
When using a mounting box, outlet should be sealed in
such a manner that the box itself did not get hot air.
3.5 Combustion Air Supply
Air needed for combustion should not be sucked
from the cabin or luggage compartment of a
vehicle.
Inlet of the intake pipe should be positioned in such a way
that it is protected from sucking snow or getting clogged, and
if any water gets into it, it should freely drain out.
For boat application combustion air intake should be
connected to thru-hull fitting (supplied separately).
3.6 Exhaust System
Exhaust pipe, made from flexible corrugated metal, should
be cut to the required length.
The exhaust pipe is attached to the heater with a clamp.
For a better contact of the exhaust pipe and the heater fitting, a
few cuts of 15-20 mm in length should be made in the pipe, but
not beyond the exhaust fitting of the heater.

18
The end of the exhaust pipe should not touch
the rubber sealing of the heater.
When mounting the exhaust pipe, care should
be taken to eliminate penetration of exhaust
gases into the cabin or their sucking by the fan
through the radiator of the cab heater.
At the end of the exhaust pipe a shield is
installed, which necessary for stable operation
at low heating modes (Fig.14).
Exhaust gases have to be removed outside of the
vehicle
Exhaust gases should be discharged to the outside.
Furthermore, the gases should not adversely affect the operation
of vehicle units. The outlet of the exhaust pipe should be in such
a position that would prevent clogging or entering of snow, and
also provide for free drain of any water that got into it.
For boat application exhaust pipe should be connected to
exhaust double-wall thru-hull fitting (supplied separately).
Heaters are equipped with a muffler attached to the
exhaust pipe. Depending on the mounting location of the
muffler, cuts are made to the exhaust pipe. For better fixation
of the exhaust pipe on the fittings of the muffler, it is necessary
to make cuts 15-20 mm in length, but not extending beyond the
male fittings of the muffler. Installation of the muffler is shown
in Fig.15.
3.7 Installation of Air Intake and Exhaust Pipe

19
Both exhaust and intake pipes should be positioned
inclined downward from the heater (Fig.16). If this is not
possible, then a hole Ø3 mm should be made at the lowest
point to drain condensate.
Exhaust gas outlet and combustion air inlet should be
positioned in such a manner as to eliminate the possibility of
re-suction of exhaust gases
The air intake inlet and the outlet of the exhaust
pipe shall not face incoming air flow when the
vehicle is in motion (Fig.17).
When installing the heater inside van bodies
(insulated vans, box vans, etc.), the exhaust pipe
outlet and the air intake shall not be placed on
the opposite sides of the vehicle (Fig.18).
The correct installation of the exhaust and air intake
pipes is on one side. The distance between them should
exclude re-suction of exhaust gases through the air intake (at
least 200mm).
Under adverse conditions (strong wind, occasional
atmospheric pressure changes), failure to comply with these
recommendations not only prevents the discharge of exhaust
gases, but also creates an additional depression near the air
intake.
As a result, normal operation of the burner is impeded,
it gets clogged with soot, and the life of the heater shortens.
In rare cases, failure to comply with this
recommendation may lead to penetration of flame into the air
blower.
