material damage or environmental damage.
Attention!
This symbol warns about a situation that deserves
your attention. Ignoring this warning can lead to
material damage. .
Information(s)
This symbol indicates that somewhere else in the
manual you can fi nd more information about this
topic or it will refer you to a local standard.
1.2 Improper use
The Udara air heater is intended for heating systems
based on hot air where both the heated and the intake
air is distributed through a system of ducts.
If the appliance is used inexpertly or improperly, a
situation may be created that entails danger for the
user or third parties or can lead to damage to the
appliance or the environment.
You may only install the Udara if you combine the
appliance with the accessories listed in the manual for
the combustion air supply (CAS) and fl ue gas outlet
(FGO).
As an installer or user you have the obligation to
closely follow the instructions contained in the manual
of the appliance or the possible accessories. You
must, moreover, respect all inspection and
maintenance conditions
You must connect the appliance electrically in
accordance with the protection degree specifi ed on
the nameplate and in accordance with the locally
applicable regulations.
If you implement changes to the appliance that are
not described in the manual, you must ask for written
permission from the manufacturer.
Transgressions to these instructions will be deemed
not according to the regulations and may lead to
dangerous situations or material damage regarding
which the manufacturer rejects any responsibility.
1.3 General safety instructions
The installation, mounting, disassembly,
commissioning, maintenance and repair must only be
performed by professionals. They must have all legal
qualifi cations and, by preference, they must have
followed training at the manufacturer of the appliance.
As a user, you must closely follow the maintenance
instructions. Ask your installer to go through this
section if you have any questions.
1.3.1 Danger of fatal injury because of gas leaks
With regard to gas smells in buildings:
• extinguish all naked fl ames (such as from
smoking, cookers, etc.).
• Do not operate any doorbells, switches, plugs,
telephones, entry panels or other devices
• Close the main gas valve and the gas valve on the
product.
• Open windows and doors.
• Evacuate the building and stop third parties from
entering the building.
• Warn the fi re brigade using a telephone
connection outside the building (for example, at
the neighbours).
• If the leak occurs in front of the gas meter, warn
the energy company.
Liquid gas is heavier than air and will collect near the
fl oor. If the appliance is being installed below ground
level, leaking liquid gas will collect and, therefore,
there will be an explosion risk.
• Ensure that liquid gas can never escape from the
appliance or the gas pipe.
1.3.2 Danger of fatal injury because of fl ammable
substances
Do not use or keep explosive or fl ammable substances
(petrol, thinner, paper, etc.) near the appliance.
1.3.3 Danger of fatal injury because of
combustion gases escaping
If fl ue gases escape, this can lead to dangerous
situations.
• Only use the appliance with a fully installed
CAS/FGO
IHL_UDARA_2016_11_04_BEGB
5
• Always use the appliance with an installed front
cover.
A dangerous situation may occur if the appliance is
supplied with insuffi cient combustion air.
• Ensure there is a permanent and unobstructed
air supply to the set-up room of the appliance in
accordance with the applicable standards.
If you smell fl ue gases or you suspect there is a
combustion gas leak, you must intervene immediately.
• Open windows and doors and ventilate the
building.
• Switch off the product.
• Consult your installer and have the combustion
circuit checked for leaks or obstructions.
If the condensate trap is empty, fl ue gas may leak.
• Always use the appliance with a fully fi lled
condensate trap.
1.3.4 Danger of fatal injury because of electric
shocks
If you touch components that carry a current, there is
a danger of fatal injury because of an electric shock.
Before you work on the product:
• Ensure that the current to the appliance has been
disconnected.
• Protect against reconnection.
• Always wait a few minutes so that the capacitors in
motor controls, etc., are discharged.
1.3.5 Danger of fatal injury because of changes
Unauthorised changes to the product or set-up room
can lead to dangerous situations.
• Never remove, bypass or change the temperature
probes in the appliance.
• Sealed parts in the appliance must not be opened.
• Never change the piping for gas or the CAS/FGO
and the wiring for the voltage.
• The condensate discharge must always be
present and changes must never be implemented
regarding the condensate discharge.
1.3.6 Danger of fi re or becoming trapped
If you want to connect the appliance without ductwork,
you must:
• Install a vent on the suction opening that impedes
access to the fan compartment;
• Install a vent or blow plenum on the blow hole so
that there is no direct access to the heat
exchanger compartment. This vent or plenum
must also ensure that fl ammable material cannot
fall on the heat exchanger.
These accessories are available from our range. If you
do not know which accessories you need, you can
contact your dealer for additional information.
Some parts of the appliance can become very hot
during and shortly after use.
• Only carry out activities such as maintenance after
the appliance has completely cooled down.
1.3.7 Risk of corrosion damage
Chemical products such as solvents, paints,
adhesives, soaps, etc., may lead to corrosion in the air
heater or in the CAS/FGO.
• Ensure that the combustion air is always dust-free
and is not polluted by fl uorine, chlorine, sulphur
and other contaminants.
• If the combustion air is being supplied through a
chimney duct, it must not have been used in the
past as an FGO for fuel oil devices, coal or wood
burners or open fi replaces.
• If the appliance is set up in launderettes, ironing
parlours, swimming pool rooms, etc., the
appliance must be installed in a separate
set-up room in which the ambient air is free from
chemical contaminants.
• Combustion air that is insuffi ciently dust-free
can lead to an unreliable ignition and, in extreme
cases, even damage to the heat exchanger
because of internal dirt. If this risk exists, you must
order an intake fi lter for the CAS that is available
as an accessory.
1.3.8 Material damage because of unsuitable
tools
In addition to conventional tools, you also need a
number of specifi c tools to work on or maintain the
Udara appliance.
• You need a special square drill bit, size 2, to
loosen the tapping screws.
• In addition, you need a set of Allen wrenches with
a rounded side.
• Using a 0-10 Nm torque wrench is recommended.
• You must have a fl ue gas analysing device that
can measure the following substances in the fl ue
gases: NOx (nitrogen oxides), O2 (residual
oxygen) and CO (carbon monoxide). If your
appliance cannot measure NOx, it is strictly
prohibited to change the adjustment of the
appliance or to perform a manual calibration.
1.3.9 Material damage because of frost
If the appliance is not set up frost-free, the appliance
can be damaged. If the temperature of the suctioned
air drops far below freezing point, frost can even occur
in the heat exchanger itself.
In such a case, a bypass must be made using the air
outlet duct to the suction duct so that the suctioned air
is preheated.
• Also make absolutely sure that the environment in
which the appliance is being installed cannot lead
to any dangers because of fl oating dust and/or
fl ammable or corrosive substances or fumes.

IHL_UDARA_2016_11_04_BEGB
1.3.10 Material damage to the fl exible gas tube
The fl exible gas tube can be damaged because of a
heavy load due to a weight or repeated and
unnecessary bending.
• Do not suspend the burner and mixing box from
the fl exible corrugated gas tube during
maintenance
1.3.11 Material damage after water ingress
If the appliance or parts of it are exposed to water
ingress, the appliance must be put out of service
immediately. All safety components that are exposed
to water must, subsequently, be replaced

2 General information
2.1 Description
Multicalor Udara air heaters are gas-fi red condensing
and modulating appliances with a cleaner combustion,
automatically controlled direct current fans and a
gas-adaptive control.
2.2 Gas category
The appliance has been set for being fi red with natural
gas of the second family (I2N) ex-factory. If you want
to use the appliance with propane, the burner
management control system must be adjusted and a
new nameplate must be added to the appliance. Only
an engineer appointed by the manufacture can do this.
The appliance is delivered ready for use. It is
suffi cient to connect the fl ue gas outlet (FGO) duct,
the combustion air supply (CAS) duct, the gas pipe,
the condensate discharge, the air ducts and the power
lines.
2.3 Standard version
The standard version of the appliance is used for the
distribution of recycled air to which no more than 25%
of outdoor air is added or for the distribution of outdoor
air to heat recovery. The appliance will work in this
mode ex-factory.
2.5.1 Upfl ow
Suctioning takes place at the bottom of the appliance
with regard to an upfl ow version. The blowing out of
the hot air takes place at the top of the appliance. This
is also sometimes called a top blowing version.
The fi lter is at the bottom of the air heater as standard.
If you want to connect the appliance on its side, you
must order an optional fi lter frame.
If side connection is required, we recommend ordering
a long tool life fi lter from the accessory range and not
to opt for the standard side fi lter frame with regard to
the Udara 40 and 50.
2.5.2 Downfl ow
Suctioning takes place at the top of the appliance with
regard to a downfl ow appliance. The blowing out of the
hot air takes place at the bottom of the appliance. This
is also sometimes called a bottom blowing version.
DF is added to the appliance type with regard to the
downfl ow version.
2.4 Outdoor air version
The outdoor air version of the appliance is used to
distribute air to which more than 25% of outdoor air is
added.
Warning!
If the appliance is deployed as an outdoor air
version, you must perform the changes specifi ed
below to prevent damaging the appliance.
If you want to deploy the appliance as an outdoor air
appliance, you must order an additional insulation
set to insulate the fan compartment of the Udara air
heater. This will limit condensation on the outer
housing of the appliance.
In addition, the condensate trap must be installed
outside the appliance using an extended hose set with
regard to the upfl ow versions of the Udara.
The condensate hoses in the fan compartment must
also be safeguarded from frost, for example, by
installing thermal insulation and/or a heating ribbon
around the hoses.
If the temperature of the suctioned air drops below
freezing point, the condensate in the heat exchanger
itself can freeze. In such a case, a bypass must be
made using the air outlet duct to the suction duct so
that the suctioned air is preheated. 2
2.5 Versions
The Multicalor Udara appliances are available in 2
versions: upfl ow and downfl ow.

Danger!
• Protect the fl ue gas outlet with a non-fl amma-
ble sheath if it is being guided through walls or
cavities made of fl ammable material. Always
respect the free space of 25 mm between this
sheath and the discharge pipe.
• Every Udara appliance must be equipped with
an individual FGO/CAS. Shared discharge
systems are not permitted.
• The burner compartment of the Udara is part of
the combustion circuit. The appliance must not
be put into operation with a missing front cover.
Information(s)
In some countries, the use of CAS or FGO pipes
that have not been enclosed in metal or other fi re-
retardant material is prohibited. Always consult the
local standards before installing.
Udara air heaters are appliances that, by preference,
are set up as a closed appliance (type C). This means
that the appliance must be connected through a parallel or concentric fl ue gas outlet (FGO) and combustion
air supply (CAS).
Combustion gases are discharged through one pipe
and air required for the combustion is supplied through
the other pipe.
