2.3. Power supply
Theheatermustbecorrectlyconnectedtoane󰀨ectiveearthing
system,ttedincompliancewithcurrentlegislation.
Cautions:
• Checkthee󰀩ciencyoftheearthingsystemand,ifrequired,
calloutaqualiedengineer.
• Check that the mains power supply is the same as the
power input stated on the equipment nameplate and in
this manual.
• Donotreverseliveandneutral;theheatercanbeconnected
tothemainspowersupplywithaplug-socketonlyifthe
latterdoesnotallowliveandneutraltobeswapped.
• The electrical system and, more specically, 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 qualied 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;
• donotleavetheequipmentexposedtotheelements(rain,
sun etc...) unless it is adequately protected;
• do not use the gas pipes to earth electrical equipment;
• donotwettheheaterwithwaterorotheruids;
• donotplaceanyobjectovertheequipment;
• donottouchthemovingpartsoftheheater.
Avoidcontactwithhotheatersurfaces.Suchsurfaces,generally
locatedneartheame,overheatduringoperationandremain
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 thermalstation and close
themanualvalveontheductwhichbringsthe fueltotheburner.
If, instead, the equipment is not to be used any more, perform
the following operations:
• aqualiedpersonshalldisconnectthepowersupplycable
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
Theroomwheregasredheaterwillbeinstalledmustbeprovided
withoneormoreairvents.Theseairventsmustbetted
• ushtotheceilingforgaseswithdensitylowerthan0.8sqm;
• ush to the oor for gases with density higher than or
equal to 0.8sqm.
Theairventsmustbettedtowallsfacingtheopenair.The
sectionsmustbesizedaccordingtotheheatoutputinstalled.
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. C02value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:
• stagnationintheroomofanytoxicand/orexplosivemixture;
• smoulderingcombustion:dangerous,expensive,pollutant.
Theheater,ifnotbuiltforoutdoorinstallation,shallbesheltered
from rain, snow, and frost. If air is pulled from outdoor, the
intakemustbeprotectedbyaraindeectororsimilardevice
thatpreventswaterfrompenetratingintotheheater.
Theroomwheretheheater-burnergroupisinstalledmustbe
cleananddeprivedofvolatilesubstancesthatcanbedrawnby
the fan and obstruct burner inner hoses or combustion head.
Dust itself can be a problem if it is left depositing on fan blades,
thusreducingfanowrateandmakingcombustionpolluting.
Moreoverdustcandepositonthebackofamestabilitydisk
incombustionhead,degradingair-fuelmixingratio.
2.6. Maintenance
Before carrying out any cleaning and maintenance operations,
isolate the boiler from the mains power supply using the switch
locatedontheelectricalsystemand/orontheshut-outdevices.
If the equipment is faulty and/or incorrectly operating, switch it
o󰀨anddonotattempttorepairityourself,butcontactourlocal
TechnicalServiceCentre.
All repairs must be carried out by using genuine spare parts.
Failuretocomplywiththeaboveinstructionscouldcompromise
thesafetyoftheequipmentandinvalidatethewarranty.

sound directly produced by the heater.
Any sound source in a closed surrounding
producesasoundlevelthatisthesumofdirect
anddi󰀨usesounds.Directsoundistheoutput
from the source while di󰀨use sound depends
on the acoustic characteristics of the installation
room (size, average sound absorption, etc.).
Obviously,theincidenceofdi󰀨usesoundover
directsoundisgreaterasthedistancefromsound
source grows.
InPK-Aheatersforindoorinstallation,thenoise
generated on intake by centrifugal fans is the
maincomponentofnoiseproducedbytheheater,
sinceonlyaprotectivegridisinstalled.
Thevalueondeliveryislowersinceexchanger,
panelling and plenum help reducing it.
