This section must be carefully studied by the installer

and the user.

1.1 Warnings and symbols

A number of symbols point out possible dangers that

may occur when installing or using the appliance.

Depending on the seriousness of the potential

situation, other symbols, icons or words are used.

Always take these warnings seriously and never ignore

them.

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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speci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.

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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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.

• Also make absolutely sure that the environment in

heater or in the CAS/FGO.

• Ensure that the combustion air is always dust-free

andisnotpollutedby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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insu󰀩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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speci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.

• Youmusthaveauegasanalysingdevicethat

canmeasurethefollowingsubstancesinthe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.

IHL_UDARA_2023_BEGB

1.3.10 Materialdamagetotheexiblegastube

Theexiblegastubecanbedamagedbecauseofa

heavy load due to a weight or repeated and

unnecessary bending.

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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

su󰀩cienttoconnectthe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.

2.4 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 speci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upowversionsoftheUdara.
