Regulations!
Extract from Directive 2001 / 56 / EC Annex VII and
ECE Regulation No. 122 of the European Parlia­ment and of the Council

General regulations

• Operating state display

– A clearly visible operating display in the user’s field of

vision must indicate when the heater is switched on
and off.

Regulations concerning installation in the vehicle

• Scope

– Subject to differing stipulations in the following

section, combustion heaters must be installed ac­cording to the provisions of Annex VII.

– It is assumed that Class O vehicles with heaters for

liquid fuel conform to the provisions of the directive.

• Arrangement of the heater

– Parts of the structure and other components near

the heater must be protected from excessive heat
exposure and possible fuel or oil contamination.

– The heater must not pose a fire hazard even when it

overheats. This requirement is deemed to be fulfilled
if adequate clearance is ensured for all parts during
installation, sufficient ventilation is provided and
fireproof materials or heat shields are used.

– The heater must not be mounted in the passen-

ger compartment of vehicles in class M2 and M3.
However, a heater in a hermetically sealed enclosure
which also complies with the aforementioned condi­tions may be used.

– The factory nameplate or duplicate must be affixed

so that it can still be easily read when the heater is
installed in the vehicle.

– All appropriate precautions must be taken when

arranging the heater to minimise the risk of injuries
to persons or damage to other property.

• Fuel supply

– The fuel intake connection must not be located in

the passenger compartment and must be sealed
with a properly closing lid to prevent any fuel leaks.

– In heaters for liquid fuel where the heater fuel is

separate from the vehicle fuel, the type of fuel and
intake connection must be clearly identified.

– A warning sign is to be fixed to the intake connec-

tion indicating that the heater must be switched off
before refuelling.

• Exhaust system

– The exhaust outlet must be arranged so as to

prevent any penetration of exhaust fumes into the
vehicle interior through the ventilation system, warm
air intakes or open windows.

• Combustion air intake

– The air for the heater’s combustion chamber must

not be sucked in from the vehicle’s passenger com­partment.

– The air intake must be arranged or protected in such

a way that it cannot be blocked by other objects.

• Hot air intake

– The heater’s air supply must consist of fresh air or

circulated air and must be sucked in from a clean
area, which cannot be contaminated by exhaust
fumes from the engine, the combustion heater or
any other source in the vehicle.

– The intake pipe must be protected by a grid or other

suitable means.

• Hot air outlet

– The hot air pipes within the vehicle must be ar-

ranged or protected in such a way that there is no
risk of injury or damage if they are touched.

– The air outlet must be arranged or protected in such

a way that it cannot be blocked by any objects.

• Automatic control of the heating system

– If the engine fails, the heating system must be auto-

matically switched off and the fuel supply stopped
within 5 seconds. The heater may remain in opera­tion if a manual device has already been activated.

of this annex.

Technical regulations

General provisions (EX / II, EX / III, AT, FL and OX
vehicles)

Avoid heating and ignition

Combustion heaters and their exhaust pipes must be
designed, arranged, protected or covered so that any
unacceptable risk of heating or ignition of the load is
avoided. This regulation is deemed to be complied with
if the fuel tank and the exhaust system of the unit con­form to the regulations described in the “Fuel tank” and
“Exhaust system and exhaust pipe layout” paragraphs.
The complete vehicle must be checked for compliance
with these regulations.

Fuel tanks

Fuel tanks for supplying the heater shall conform to the
following regulations:

• In the event of any leakage, the fuel shall drain to the

ground without coming into contact with hot parts of
the vehicle or the load;

• fuel tanks containing petrol shall be equipped with

an effective flame trap at the filler opening or with a
closure enabling the opening to be kept hermetically
sealed.

Exhaust system and exhaust pipe layout

The exhaust system as well as the exhaust pipes shall
laid out or protected to avoid any danger to the load
through heating or ignition. Parts of the exhaust system
situated directly below the fuel tank (diesel) shall have
a clearance of at least 100 mm or be protected by a
thermal shield.

Switching on the combustion heater

The combustion heater may only be switched on manu­ally. Automatic switching on via a programmable switch
is not permitted.

EX / II and EX / III vehicles

FL vehicles

Combustion heaters must be able to be taken out of
service/disabled at least by the methods described in
the following:
a) Switching off manually in the driver‘s cabin
b) Switching off the vehicle‘s engine; in this case the

heater may be manually switched back on by the
vehicle driver;

c) Starting up of a feed pump installed in the vehicle for

the dangerous goods carried.

Combustion heater afterrun
Afterrunning of the switched off combustion heater is
permitted. In the cases named in the „FL vehicles“ para­graph under letters b) and c) the supply of combustion
air must be interrupted by suitable means after a maxi­mum afterrun period of 40 seconds. Only combustion
heaters whose heat exchangers are verifiably not dam­aged by the reduced afterrun period of 40 seconds
beyond their usual use period may be used.

Please note!

• Compliance with the statutory regulations, the addi­tional regulations and safety instructions is prerequisite
for guarantee and liability claims.

Failure to comply with the statutory regulations and

safety instructions and incorrect repairs even when
using original spare parts make the guarantee null and
void and preclude any liability for Eberspächer Climate

The parts for the hot air system are included in the
scope of supply of the „Universal“ and „Plus“ instal­lation kits.

The „Plus“ installation kit does not contain any exible
pipes, these must be ordered separately. Refer to the

product information for the Order No.

Danger!

Risk of burning and injuries!

• The hoses of the heater air system and the hot air
outlet are to be routed and fastened in such a way
that they pose no temperature risk to people, animals
or materials sensitive to temperature from radiation /
contact or blowing directly. If necessary, a cover is to
be fitted to the heater air system or hot air outlet.

• The outflow hood must be fitted on the hot air outflow
side.

• A safety grid must be fitted to the heater air intake
side and outflow side if no air hoses are mounted, to
prevent any injuries from the heater air fan or burns
from the heat exchanger.

• High temperatures occur in the heater air system dur­ing and after the heater has been working. This is why
it is important to avoid working in the vicinity of the
heater air system while the heater is working. In such
cases, switch the heater off beforehand and wait until
all parts have cooled down completely. If necessary,
wear safety gloves.

Caution!

• The heater air intake openings must be arranged in
such a way that under normal circumstances, it is
not possible for exhaust from the vehicle engine and
heater to be sucked into the system, or for the heating
air to be contaminated with dust, salt spray,etc.

• For circulating air, position the circulating air intake
in such a way that the outflowing hot air cannot be
directly sucked in again.

• In the event of possible overheating, it is possible for
local lot air temperatures of up to max. 150 °C or
surface temperatures of up to max. 90 °C to occur
immediately before the defect shutdown. Therefore
only temperature-resistant hot air hoses approved by
us must be used for the heater air system!

• When checking the functions, the mean outflow tem­perature measured after the heater has been running
about 10 minutes at approx. 30 cm from the outlet
should not exceed 110 °C (at an intake temperature of
approx. 20 °C).

• If there is a risk of the driver and passengers touching
the heater when the vehicle is being driven normally, a
contact protection device must be fitted.

Exhaust system

Mounting the exhaust system

The “Universal” and “Plus” installation kits include a
exible exhaust pipe, inner Ø 24 mm, 1000 mm long

and an exhaust silencer. The flexible exhaust pipe
can be shortened to 20 cm or lengthened to max.

2 m, depending on the installation conditions.

Fasten the exhaust silencer to a suitable position in
the vehicle.

Use a pipe clip to x a short exhaust pipe end (with
end sleeve) to the exhaust silencer (Anzugsdrehmo-

ment 7

+0.5

Nm).

Use a pipe clip (tightening torque 7

+0.5

Nm) to fix a
short exhaust end pipe (with end sleeve) to the exhaust
silencer.

Caution!
Safety instructions!

The whole exhaust system gets very hot during and
immediately after the heater has been working. This is
the reason why the exhaust system must be installed
according to these instructions.

• The exhaust outlet must end in the open air.

• The exhaust pipe must not protrude beyond the lateral

limits of the vehicle.

• Install the exhaust pipe sloping slightly downwards. If

necessary, make a drain hole approx. Ø 5 mm at the
lowest point to drain off condensation.

• Important functional parts of the vehicle must not be

impaired (keep sufficient clearance).

• Mount the exhaust pipe with sufficient clearance to

heat-sensitive parts. Pay particular attention to fuel
pipes (plastic or metal), electrical cables and brake
hoses etc.!

• Exhaust pipes must be fastened safely (recommended

clearance of 50 cm) to avoid damage from vibrations.

• Route the exhaust system so that the emitted fumes

are not sucked in with the combustion air.

• The mouth of the exhaust pipe must not get clogged

by dirt and snow.

• The mouth of the exhaust pipe must not point in the

direction of travel.

• Always fasten the exhaust silencer to the vehicle.

Danger!
Risk of injuries and burns!

Every type of combustion produces high tempera­tures and toxic exhaust fumes. This is the reason why
the exhaust system must be installed according to
these instructions.

• Do not perform any work on the exhaust system while
the heater is working.

• Before working on the exhaust system, first switch the
heater off and wait until all parts have cooled down
completely, wear safety gloves if necessary.

• Do not inhale exhaust fumes.

• Comply with the regulations and safety instructions

for this chapter on page 4 – 7.

• If a silencer is tted, the exhaust end pipe must

be much shorter than the flexible exhaust pipe be­tween the heater and the exhaust silencer.

• Small arrows indicating the direction of ow have

been cast into the fittings to differentiate between
the combustion air and the exhaust fittings at the

heater (see diagram page 23).

• To prevent contact erosion, the clips used to fix the
exhaust pipe must be made of stainless steel. The
order No. for the stainless steel fixing clips is given in
the product information.

Please note!

The heater is not approved for operation with bio

diesel fuel (FAME). Up to 10 % bio diesel fuel (FAME)

may be added.

Airtronic M

The diesel heater is approved for operation with bio

diesel fuel (FAME) according to DIN EN 14 214.

• Bio diesel fuel (FAME) according to DIN EN 14 214
– during the winter months is adapted to low tem-

peratures from 0 °C to –20 °C.

– The Flowability reduces at temperatures below 0 °C.

• When using 100 % bio diesel, the heater should be
operated twice a year with diesel fuel (in the middle
and at the end of a heating period) in order to burn off
any possible biodiesel residues deposited.

To do so, let the vehicle tank run almost empty and

then fill with diesel fuel. While running on this tank
filling, switch the heater on 2 to 3 times for 30 minutes
at a time at the highest temperature setting.

• When operating with diesel / bio diesel mixtures of up
to 50 % bio diesel, intermediate operation with pure
diesel fuel is not necessary.

Please note!

Operating instructions

The heater is operated by a control element.
Detailed operating instructions are enclosed with the
control unit.

The workshop / garage installing the heater will issue
you with the operating instructions.

Important instructions for operation

Safety checks before the start

After a lengthy period of non-use (summer months)

check that all parts fit securely (tighten screws where

necessary).

Check the fuel system visually for any leaks.

Heating at high altitudes

• up to 1500 m altitude, heating mode is possible wit­hout altitude adjustment.

• from 1500 m – 3000 m, heating mode for short stays
(e.g. if crossing a pass or stopping for a break) is
possible without adjusting the heater altitude.

In case of a lengthy stay, e.g. winter camping, it is

necessary to adjust the heater‘s altitude.

The heater‘s altitude is adjusted by installing an air

pressure sensor; this is included in the altitude kit –
Order No. 22 1000 33 22 00.

Please note!

Heaters suitable for high altitudes are labelled with
“HKit” on the side nameplate.

Initial commissioning

The following points are to be checked by the com­pany installing the heater during initial commissioning.

• After installation of the heater, the coolant circuit and
the whole fuel supply system must be vented carefully.
Comply with the instructions issued by the vehicle
manufacturer.

• During the trial run of the heater, check all water and
fuel connections for leaks and firm fitting.

• If the heater shows a fault during operation, find and
eliminate the cause of the fault using a diagnosis unit.

Please note!

During the initial startup of the heater, odours can be
produced for a short time. This is fully normal during the
first few minutes of operation and does not indicate a
malfunction in the heater.

Please note!

Description of functions

Switching on

When the heater is switched on, the control lamp in

the control element lights up.
The glow plug is switched on and the fan starts at
low speed.

Please note!

If there is still too much residual heat in the heat

exchanger from when the heater was last used, rstly
only the fan starts up (cold blowing).
Once the residual heat has been cleared, the heater

starts.

Starting Airtronic

After approx. 65 seconds the fuel supply starts and
the fuel / air mixture in the combustion chamber
ignites.

Once the combined sensor (ame sensor) has de­tected the ame, the glow plug is switched off after

60 seconds. The heater is now in standard operation.

Starting Airtronic M

After approx. 60 seconds the fuel supply starts and
the fuel / air mixture in the combustion chamber
ignites.

After the ame sensor has detected the ame, the

glow plug is switched off after approx. 90 sec. The
heater is now in standard operation.

After another 120 seconds, the heater has reached
the “POWER” stage (maximum fuel quantity, maxi­mum fan speed).

Temperature selection with the control element

The control can be used to preselect an interior tem­perature.
The resulting temperature can be within the range of
+10 °C to +30 °C and depends on the selected heater,
on the size of the space to be heated and on the pre­vailing outdoor temperature.
The setting to be selected at the control is an empirical
value.

Operation and function

4

Control in the heating mode

During the heating mode, the room temperature or the

temperature of the sucked in heating air is constantly
measured.
If the temperature is higher than the temperature

selected on the control element, the heater starts

to regulate its output. There are 4 control stages so
that the outflow of heat produced by the heater can
be adjusted finely to the heating requirements. Fan
speed and fuel quantity correspond to the particular
control stage.
If the set temperature is still exceeded in the smallest

control stage, the heater goes to the “OFF” stage with

the fan running on for approx. 4 minutes to cool off.
Then the fan continues at minimum speed (circula-

tion mode) or is switched off (fresh air mode) until the

heater is started again.

Ventilating mode

In the ventilating mode, rst the changeover switch

“heating / venting” has to be activated and then the
heater is switched on.

Switching off

When the heater is switched off, the control lamp

goes off and the fuel supply is switched off.
The fan runs on for approx. 4 minutes to cool down.

While the fan is running on, the glow plug is switched

on for approx. 40 seconds to clean.
Special case:
If no fuel has been supplied or if the heater is in

the “OFF” stage until it is switched off, the heater is

stopped without any after running.

31

Forced shutdown in ADR mode (only for diesel
heaters 24 volt)

In vehicles for the transport of dangerous goods (e.g.

tanker trucks), the heater must be switched off be­fore the truck drives into a danger area (renery, fuel
service station, etc.).

Failure to comply results in the heater switching off
automatically when:

• The vehicle engine is switched off.

• An additional unit is started up (e.g. auxiliary drive for
unloading pump etc.).

The fan then runs on for max. 40 seconds.

Control and safety devices

• If the heater does not ignite within 90 seconds after
starting the fuel pump, the start is repeated. If the
heater still does not ignite after another 90 seconds of
pumping fuel, the heater is switched off, i.e. the fuel
supply is off and the fan runs on for approx. 4 min­utes.

• If the flame goes off by itself during operation, the
heater is restarted. If the heater does not ignite within
90 seconds after the fuel pump has started, or ignites
and goes off again within 15 minutes, the heater is
switched off, i.e. the fuel supply is off and the fan runs
on for approx. 4 minutes. This status can be remedied
by briefly switching off and on again. Do not repeat
the switching off/on routine more than twice.

• In the case of overheating, the combined sensor
(flame sensor / overheating sensor) triggers, the fuel
supply is interrupted and the heater switched off.
Once the cause of the overheating has been elimi­nated, the heater can be re-started by switching off
and on again.

• If the lower or upper voltage limit is reached, the
heater is switched off after 20 seconds.

• The heater does not start up when the glow plug is
defect or when the electric lead to the dosing pump is
interrupted.

• If the combined sensor (flame sensor / overheating
sensor) is defect or the electric lead interrupted, the
heater starts up and is then switched off again during
the start phase.

• The speed of the fan motor is monitored continu­ously. If the fan motor does not start up or if the speed
deviates by more than 10%, the heater is switched off
after 30 sec.

• When the heater is switched off, the glow plug is
switched on for 40 seconds (after-glowing) while the
fan runs on to clean off any combustion residues.

Please note!

Do not switch the heater off and on again more
than twice.

Heater wiring

The electronic control box is integrated in the heater,
which considerably simplifies the wiring required during
installation.

Caution!
Safety instructions for wiring the heater!

The heater is to be connected up electrically accord­ing to the EMC directives.
EMC can be affected if the heater is not connected

up correctly. For this reason, comply with the following

instructions:

• Ensure that the insulation of electrical cables is not
damaged. Avoid: chafing, kinking, jamming or expo­sure to heat.

• In waterproof connectors, seal any connector cham­bers not in use with filler plugs to ensure they are
dirt-proof and water-proof.

• Electrical connections and ground connections must
be free of corrosion and firmly connected.

• Lubricate connections and ground connections out­side the heater interior with contact grease.

Please note!

Comply with the following when wiring the heater and
the control element:

• With the appropriate electrical wiring, the heater
fulfils the ADR regulations; please refer to the circuit
diagrams at the end of this document.

• Electrical leads, switchgear and controllers must
be arranged in the vehicle so that they can function
perfectly under normal operating conditions (e.g.heat
exposure, moisture etc.).

• The following cable cross sections are to be used
between the battery and heater. This ensures that
the max. tolerable voltage loss in the cables does not
exceed 0.5 V for 12 V or 1 V for 24 V rated voltage.

Cable cross sections for a cable length of (plus cable

+ minus cable):
– up to 5 m = cable cross section 4 mm²
– from 5 to 8 m = cable cross section 6 mm²

• f the plus cable is to be connected to the fuse box
(e.g. terminal 30), the vehicle cable from the battery to
the fuse box must be included in rating the overall ca­ble length and possibly re-dimensioned if necessary.

• Insulate unused cable ends.

Troubleshooting / Maintenance / Service

6

In case of faults, please check the following
points

• If the heater does not start after being switched on:

– Switch the heater off and on again.

• If the heater still does not start, check whether:

– There is fuel in the tank?
– The fuses are OK?

– The electrical cables, connections etc. are OK?

– Anything is clogging the combustion air supply
or exhaust system?

Troubleshooting

If the heater remains faulty even after these points

have been checked, or another malfunction occurs in
your heater, please contact:

• For installation ex works, your contract workshop.

• For subsequent installation, the workshop who
installed your heater.

Please note that warranty claims can be become void
if the heater is changed by a third party or by this
installation of third party parts.

Maintenance instructions

• Switch the heater on once a month for about 10 min­utes, even outside the heating period.

• Before the heating period starts, the heater should
undergo a trial run. If persistent extreme smoke devel­ops, unusual burning noises or a clear fuel smell can
be perceived or if electric / electronic parts heat up,
the heater must be switched off and put out of service
by removing the fuse. In this case, the heater should
not be started up again until it has been checked by
qualified staff who have been trained on Eberspächer
heaters.

• Check the openings of the combustion air supply and
exhaust system after longer standstill periods, clean if
necessary!
