TERMOSTUFE A PELLETS
The UNGARO Bico Fire Thermostoves, that work esclusively with pellets and wood, are equipped
with two separate combustion chambers, two separate smoke pipes and two heat exchanges in cop-
per, which permit the development of approx. a 90% return.
They are doted with an electronic card that permitsthe regulation of the temperature in the pellet area
as in the wood area. The Bico-Fire is equippedwith a Chronothermostat that makes possibile the
turning on and oft automatically which automates the running of the thermostove (the Chronothermo-
stat works on the pellet area of the stove). The Bico-Fire brings heat to the systems radiators with a
thermic potency that autoregulates its functioningaccording to area to be heated. It is sufticient to set
systems heatingwater temperature (60°c + 75°C)to get comfort desired.
The UNGARO Bico-Firealso produce hot air, thanks to a fan of approx. 60m3/hthat permits a convec-
tional heating of the area where thermostove is installed.
Thanks to an optional kit,they also produce continuoushot sanitary water in a healthyand secure way
without accumulation need.
The UNGARO Bico-Fireare equipped with sophisticatedsecurity devices that guarantee efficient and
practical use.
AII they need is the refilling with wood pellets and setthe functions according to personal needs.

Génerall nstruction 3
Installation and maintenanceshould be done by qualified personnel only,in respect to existing laws
on the subject and accordingto company indications.
Before installing and maintenance of the product, it is necessary to read the included instructions
carefully.
These thermostoves must be used only for the purposes in which they are made for, therefore, re-
sponsibility for damages caused to persons, animals or things for improper use is to be retained at
the consumers expense.
The thermostove must be install,d by qualified personnelwhom will assume all responsibility
for instalment and properfunctioning of the product. Ungaro S.r.l. will not be responsible if
these precautions are not made.
Once product is unpacked,the consumer should make sure of the integrity and complete contents of
the product; if not, so the company should becontacted.
Before installation we suggest an accurate cleaning of all pipes in the system so that any residues,
that could interfere with correct functioning, may be removed.
In case the thermostove has not been in use for a long periodof time it is advisable:
.Place the general switch in the 0 position;
.Close the systemswater taps situated behindthe stove;
.If there is risk of freezing, empty the thermic and sanitary system.
The extraordinary maintenanceof the thermostove,which is on expense of the client, must be
scheduled at lease once a year,programming itwith the service technician.
Do not touch if barefootand/or any part of body iswet or damp;
It is forbidden to modifythe security or adjustmentdeviceswithout manufacturers indicationsor
Authorization;
Do not pull, unplug, or twist the elctric wires even if the stove is not connected to anelectrical outlet;
7

Avoid blocking windows doors etc. where installation is because a ventilated room is neces-
sar)' for a correct combustion.
It is obbligatory to connect externally thermic exhaust tubes and security valve.
Figure 3
UNGARO S.r.!. declines any responsibiliy in case of damage to persons or things for not ob-
serving this obbligation.
A correct installation of the smoke pipes is important, they must travel separately for a cor-
rect combustion.
The minimum sections to adopt are:
.Wood area 180 mmo
.Pellet area 80 mmo

Security Devices', 4
4.1 Breakage of the exhaust fan
Incase of blockage of the exhaust fan, the thermostoves electronic card willautomatically block the
pellets, and an alarm system isvisualized on the display stopping everything automatically (no dep).
4.2 Breakage of motor that refills pellets
In case the motor that refills pellets stops because of a coclea block or because of breakage, the
following alarm will show: in case of breakage in working phase, it will continue working until it rea-
ches a minimum level of functioning giving oft alarm (pull brac )
4.3 Breakage of circulation pump
In case the circulation pump is blocked or burns out,the thermostove goes in alarm (sic oft and
Hot h20) and the pellet area stops automatically while the wood area will continue to work. The
thermic escape valve, by opening,will avoid that the stove will go over the 100°C and thanks to auto-
matic refilling group that cools oft the thermostove.
4.4 Thermostove does not turn ON
If during the turning on phase there is not an adequatef1amedevelopmentthe thermostove will show
on display 01 "ALARM"while on display 02 in an alternatineway
"PUL BRAC-NO FIRE".
THIS ALARM ISA REMINDERTHAT BEFORE THE STARTING PHASE BEGINS, MAKE SURE
THAT THE BRACIER (the piece where pellets are released and then burn and where ashes
collect infront ofstove) IS COMPLETELY FREEOF ASHES, CLEAN AND IN THE CORRECT
POSITION.
The thermostove goes in alarm and stops automatically. After the cooling oft of the stove you can
procede to the cleaning of the bracier and a new starting. In case of testing on the part of a service
technician, the successive chapterswill explain howto bypass the various alarms.
4.5 Lack (absence) of electricity
In case there is a short lack of electricity, the thermostove will automatically turn back on. In case
there is a longer lack of electricity, it may be possibile that a small amount of smoke escapes the
stove.
THERE IS ABSOLUTELY NO SECURITY RISK.
When electricity returns and the display Di shows "ALARM" while on D2 "NO RETE", after the coo-
ling oft of the stove the braciercan be cleaned and you can procede to a new starting.
4.6 Electrical security
In case of violent lightening and therefore problemswith electrical problems, the thermostove is pro-
tected by two fuses (2,5 A 250V), situated behind the stove under the wire, slide the cover and sub-
stitute.

5.1 Assembling
The UNGARO Thermostoves must be installed by assistance centres and authorized personnelonly,
to whom this manual is destined.
5.2 Smoke Release
The smoke release system is based upon the depression (pulling) in the combustion chamberand a
light overpressure upon the smoke release (torced release). This makes it essential that the release
tube is correctly and hermeticallyinstalled, externally sealingthe connection ,to avoid the excaping
ot soot. This release can travel internallly or externallyot the abitation.
Installation of the smoke pipes:
5.3 Electric connection
In reterring to figure 8, measure and dril! holes in wall (0100 mm tor
the pellet area and 0185 mm tor the wood area), to insert the smoke
release tube, providing to install connecting T (Obbligatory) with
inspection caps, doted with chimney conducts (four winds), tor the
protection trom rain and wind. Do not position grills or other in the end
part ot the smoke pipe, that may compromise the exiting ot smoke,
and send stove in alarm (no dep, only in the pellet area).
For the keeping ot the tubes and their isolation, exclusively use mate-
riaIs that are heat resistent (up to 300°C) as alluminum tape, stone
wool, silicone tor hightemperatures.
PLEASE NOTE:
ALL PARTS OF SMOKE CONDUCT MUST BE INSPECTABLE AND
REMOVABLE TO MAKE POSSIBLE INTERNAL CLEANING.
The thermostove is providedwith an electric cable to be connected to a 230 V 50Hz + ground, obbli-
gatory as in 46/90 law. Avoid the cable coming into contactwith hot thermostove.
5.4 Air Combustion Pellet and Wood
It is obbliaatorv that air combustion be directlv taken externallv.
Every combustion phenomenon necessitates air (oxygen). Theretore, every thermostove extracts air
trom the area in which it is positionedand this air must be reintegrated.
A bad combustion may be provokedby scarse air circulation inside the habitation and this trequently
happens with new modern homes,which have hermeticwindows and doors.
The situation also becomes problematic when there are air currents on the inside ot the room. To a-
void this type ot problem we recommend the insertion ot a permanent air grill on a window or near the
thermostove.
