alWEEE-wasteelectricalandelectronicequipment”.According
to the legislation in force in Italy, professional WEEE must be
sent to treatment plants suitable for these types of waste. Please
contact the Apen Group for end-of-life products so as to obtain
all the information necessary for their correct waste disposal,
which is possible thanks to the Collective System (Union) to
which the company is associated. Please remember that product
disposal without complying with the mode described above is a
violation liable to administrative and penal sanctions.
INFORMATION FOR DISPOSAL valid abroad (EU COUN-
TRIES except Italy).
The European Directive 2012/19/EC shall be implemented in
every EU member state. There may be di󰀨erent application
modalities for the various member states, even in terms of
modality for waste disposal depending on its type (House-hold
or Professional WEEE). To this regard at the end of the life of

3. TECHNICAL FEATURES
The LRP-RAPID PRO and LK-KONDENSA series modulating
warm air heaters have been designed to heat industrial and
commercial environments.
The heater PCB continually modulates the heat output between
the minimum and maximum power, according to heating re-
quirements.
The premixing and modulating technology allows the heater to
achievee󰀩ciencyabove108%oftheL.C.V.
The heater can operate independently and can be started up
by simply connecting it to the mains power supply and to the
mains gas supply.
The heat output of these heaters ranges between 5 and 97 kW.
The units can be controlled in three ways:
• with an ON-OFF control;
• externally via modbus (through Smart Web or Easy);
• proportionally, with a 0-10 Vdc external control.
Theheatexchangercomplieswiththemanufacturingrequire-
ments for condensing warm air heaters, according to prevailing
standards (EN17082:2019).
The combustion chamber and the surfaces in contact with
condensation (such as the pipe bundle and exhaust hood),
are made of AISI 441, in order to provide high resistance to
condensation and temperature.
The following table shows the conversion of stainless steels used:
USA-AIS EN-No. COMPOSITION
AISI 441 1.4509 X2 CrTiNb 18
The innovative design and large heat exchanging surface of
the combustion chamber and of the pipes ensure optimum
e󰀩ciencyanddurability.
The burner is made entirely of stainless steel with special me-
chanical solutions to ensure optimal reliability and performance
levels, as well as high thermal and mechanical resistance.
The control located on the front panel allows the service centre
to check and view the working phases and identify any faults
that may have occurred.
Inherent Safety
Thee󰀩ciencyincreaseatminimumpowerisachievedbyusing
asophisticatedair/gasmixingtechniqueandbyregulatingat
thesametimethecombustionairowandthefuelgasow.
This technology increases the heater safety as the gas valve
suppliesthefuelaccordingtotheairow.Unlikeatmospheric
burners, the CO2content remains constant throughout the heater
operatingrange,allowingtheheatertoincreaseitse󰀩ciency
when the heat output reduces.
If there is no combustion air, the valve will not supply gas; if
thecombustionairowreduces, thevalve willautomatically
reducethegasowyetwillkeepitscombustionparameters
at optimal levels.
Low emissions
The premixed burner, in combination with the air/gas valve,
ensures"clean"e󰀩cientcombustionhavingverylowemissions.
ATTENTION: Before switching the heater on, open the
louvers by at least 45°.
