2. SAFETY-RELATED WARNINGS
The following symbol is used in this manual to attract machine
operators’ attention.
Safety rules for users or operators of the
equipment and for nearby workers.
Please nd below the safety regulations for the installation
room and the air vents.
2.1. Fuel
The heater must be matched to a suitable burner, using the
fuel chosen for the equipment.
The burner shall use the type of fuel it is set for, which is
speciedontheequipmentplateandintechnicalspecications
in burner’s Manual.
In case of a gas burner, the pressure of the gas supplying the
burner and the combustion head must be within the range of
values indicated in the manual.
Fuel oil burners can be used only for N series non-
condensing heaters. For K and R series condensing heaters
use only gas burners.
Before starting the burner/heater, check that:
• the gas mains supply data are compatible with the data
stated on the nameplate;
• the combustion air is supplied in such a way as to avoid
even partial obstructions of the intake grille;
• the gas seal of the feeding system has been tested and
approved in compliance with the applicable standards;
• the heater burner is supplied with the same type of fuel it
has been designed for;
• the unit is correctly sized to match required ow rate,
indicatedinthe manual,andincludesallsafetyandcontrol
devices required by the law;
• the inside of the gas pipes and air distribution ducts for
ducted heaters have been thoroughly cleaned;
• thefuelowrateissuitableforthepowerrequiredbythe
heater;
• thefuelsupplypressureisbetweentherangespecied
on the nameplate.
When connecting gas supply pipe to gas valve, do not
tighten excessively in order to avoid damaging sealing
gaskets.
2.2. Gas Leaks
If you smell gas:
• donotoperateelectricalswitches,thetelephoneoranyother
objectordevicethatcancausesparksornakedames;
• immediatelyopendoorsandwindowstocreateanairow
to vent the gas out of the room;
• close the gas valves;
• call for qualied sta.
• call the Fire Brigade.

2.3. Power supply
Theheatermustbecorrectlyconnectedtoaneectiveearthing
system,ttedincompliancewithcurrentlegislation.
Cautions:
• Checktheeciencyoftheearthingsystemand,ifrequired,
calloutaqualiedengineer.
• Check that the mains power supply is the same as the
power input stated on the equipment nameplate and in
this manual.
• Donotreverseliveandneutral;theheatercanbeconnected
tothemainspowersupplywithaplug-socketonlyifthe
latter does not allow live and neutral to be swapped.
• The electrical system and, more specically, the cable
section, must be suitable for the equipment maximum
power input, shown on the nameplate and in this manual.
• Do not pull electric cables and keep them away from heat
sources.
NOTE:It is compulsory to install, upstream of the power
cable, a switch with a protection (fuses or automatic),
as required by existing regulations. The switch must be
visible, accessible and placed at a distance lower than
3 metres from the control compartment; any electrical
operation (installation and maintenance) must be
performed by qualied sta.
2.4. Use
Do not allow children or inexperienced people to use any
electrically powered equipment.
The following instructions must be followed:
• do not touch the equipment with wet or damp parts of your
body and/or with bare feet;
• donotleavetheequipmentexposedtotheelements(rain,
sun etc...) unless it is adequately protected;
• do not use the gas pipes to earth electrical equipment;
• donotwettheheaterwithwaterorotheruidsunlessitis
suitably arranged for this purpose;
• do not place any object over the equipment;
• do not touch the moving parts of the heater.
Avoidcontactwithhotheatersurfaces.Suchsurfaces,generally
locatedneartheame,overheatduringoperationandremain
hot for some time after the burner has stopped.
If the equipment is not to be used for a certain period of time,
openthe main electrical switchof the thermal stationandclose
themanualvalveontheductwhichbringsthefueltotheburner.
If, instead, the equipment is not to be used any more, perform
the following operations:
• aqualiedpersonshalldisconnectthepowersupplycable
from the main switch;
• close the manual valve on the duct supplying fuel to the
burner by removing or locking the control handwheel.
2.5. Air Vents
Theroomwheregasredheaterwillbeinstalledmustbeprovided
withoneormoreairvents.Theseairventsmustbetted
• ushtotheceilingforgaseswithdensitylowerthan0.8sqm;
• ush to the oor for gases with density higher than or
equal to 0.8sqm.
Theairventsmustbettedtowallsfacingtheopenair.The
sectionsmustbesizedaccordingtotheheatoutputinstalled.
In case of doubt, measure the CO2with the burner working at
maximum output rate and the room ventilated only through the
air vents for the burner and then measure again with the door
closed. C02value must be the same under both conditions. If
in the same room there are several burners or aspirators that
can work together, measure with all the equipment working at
the same time.
Do not obstruct the room air vents, the burner fan intake
opening, any air ductwork and intake or dissipation grilles,
avoiding in this way:
• stagnationintheroomofanytoxicand/orexplosivemixture;
• smoulderingcombustion:dangerous,expensive,pollutant.
Theheater,ifnotbuiltforoutdoorinstallation,shallbesheltered
from rain, snow, and frost. If air is pulled from outdoor, the

2.6. Maintenance
Before carrying out any cleaning and maintenance operations,
isolate the boiler from the mains power supply using the switch
locatedontheelectricalsystemand/orontheshut-outdevices.
If the equipment is faulty and/or incorrectly operating, switch it

All repairs must be carried out by using genuine spare parts.
Failuretocomplywiththeaboveinstructionscouldcompromise
the safety of the equipment and invalidate the warranty.

2.10. Dismantling and demolition
Should the machine be dismantled or demolished, the person
in charge with the operation shall proceed as follows:
Disposal of end-of-life products
This equipment is marked in compliance with
European Directive 2012/19/EU on waste
electrical and electronic equipment (WEEE).
This Directive denes the rules for collecting
and recycling waste equipments throughout the
entire territory of the European Union.
WEEE contains both pollutants (that can
negatively aect the environment) and raw materials (that
can be reused). IT is therefore necessary to subject WEEE to
appropriate treatments, in order to remove and safely dispose
of pollutants and to extract and recycle raw materials. IT is
forbidden to dispose of WEEE as unsorted waste. These
operations facilitate recovery and recycling of the materials,
thus reducing the environmental impact.
NOTE: All materials recovered will be processed and
disposed of according to what provided for by the laws
in force in the country of use and/or according to the
standards indicated in the safety sheets of the chemicals.
INFORMATION FOR DISPOSAL valid in ITALY (Legislative
Decree 49/2014)
The PK series warm air heaters and relating accessories
are considered “professional 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
Groupforend-of-lifeproductssoastoobtainalltheinformation
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
COUNTRIES except Italy).
The European Directive 2012/19/EC shall be implemented in
everyEU member state. There may be dierentapplication
modalities for the various member states, even in terms of
modalityforwastedisposaldependingonitstype(House-hold
or Professional WEEE). To this regard at the end of the life of
the product, we highly recommend you call the distributor or
installer so as to obtain information on the correct disposal, in
compliance with the existing laws of the installation country.

Warm air heaters include:
• stainless steel heat exchanger
• frame and body
• centrifugal fan and electrical motor
• control panel and settings
• safety devices and controls
Stainless steel heat exchanger
The innovative design and large surface of the combustion
chamberandheatexchangerpipesensureoptimumeciency
and durability.
Combustionchamberanduegascollectorsarecompletely
made of AISI 441 stainless steel with low carbon content, as
wellasthesurfacesincontactwithuegases(tubebundle)in
order to ensure a high resistance to corrosion.
Tube bundle design is patented.
Characteristics of steel types used
Thefollowing table showsnaming correspondence ofthe steel
