GENERAL NOTES
This Instruction Manual is an integral art of the device and as such must always be ke t with the device. This is also
the case when the heater is sold to another user. The Manual must therefore be conserved and consulted carefully
before any action. In the case of damage or loss, you can at any time ask the local After Sales Service for a co y of the
Manual.
After removing the ackaging, first make sure that the contents are com lete and undamaged. If the heater does not
match with the Manual in any way, contact the Agency that sold the heater.
Installation of the BG series WARM AIR HEATER must be carried out by qualified com anies under Law 5 March 1990
n°46. On com letion of the job, they rovide the owner with a declaration of conformity of the correctly carried out
installation, that is according to the current a licable Norms requires and according to the indications rovided by the
Manufacturer in this Instruction Manual.
The heaters have been manufactured for room heating and they must be used for this ur ose, com atibly with their
erformance characteristics. The Manufacturer acce ts no contractual or extracontractual res onsibility for damage
caused to eo le, animals or ro erty, due to errors in installation, adjustment and maintenance or to im ro er use.
Excessive tem erature re resents a risk for health and a waste of energy. Avoid leaving rooms closed for long eriods of
time. O en the windows eriodically to ensure an adequate air change.
During the first start-u , there may be smells and smoke due to eva oration of the liquid used to rotect the heat
exchanger during storage; this is a normal henomenon that will disa ear after a brief o eration time. The rooms must
be adequately aerated.
On leaving the heater unused for a long eriod, you should carry out at least the following o erations:
• Turn off the main heater switch and the main lant switch.
• Close the main fuel su ly valve.
If the heater is not used for a long eriod of time, we suggest you contact the After Sales Service or other rofessionally
qualified ersonnel for restarting.
All heaters must be fitted exclusively with original accessories. The Manufacturer is not res onsible for any damage
caused by im ro er use of the heater and by the use of accessories that are not original.
All references to Law, standards, directives and technical rules in this manual are to be considered as informative only
and valid at the date of rinting of the Manual. The enforcing of new dis ositions or the alteration of current ones do not
create any Manufacturer obligations towards third arties.
Re airs and maintenance must be carried out by the After Sales Service or by qualified ersonnel as s ecified in this
Manual. Do not alter or tam er with the heater: this can create dangerous situations and the Manufacturer will not be
res onsible for any damage.
The systems that must be installed (oil i es, electrical su lies, etc.) have to be suitably fastened and must not
re resent any obstacle that could cause tri ing.
The Manufacturer is res onsible for conformity of his roduct to laws, directives and instructions standards current at
the date of sale. Knowledge and observation of legislative instruments and of standards for the design of systems, and
for installation, o eration and maintenance are the exclusive res onsibility of res ectively the designer, the installation
ersonnel and the user.
The Manufacturer is not res onsible for failure to observe the instructions in this Manual, for the consequences of any
o eration carried out that is not s ecifically foreseen, or for any translations causing erroneous inter retations.
The heater is designed for o eration at the thermal ower and the airflow rate as s ecified in the Technical Data
Cha ter. A thermal ower that is too low and/or an airflow that is too high can lead to condensation in the flue, with
consequent irre arable corrosion to the heat exchanger. A thermal ower that is too high and/or an airflow that is too
low cause abnormal overheating of the heat exchanger with consequent actuation of the safety systems and damage to
the heat exchanger.

FUNDAMENTAL SAFETY RULES
The use of devices that em loy electrical energy and/or fuel oil requires the observance of some fundamental safety
rules such as:
Children ad unassisted disabled ersons must not use the warm air heaters.
Do not o erate electrical equi ment such as switches, electric household equi ment etc if you can smell fuel or other
combustibles. In this case:
• O en the doors and windows to aerate the room.
• Close the fuel su ly valves.
• Call in quickly the After Sales Service or other rofessionally qualified ersonnel.
Do not touch the heater if you are barefoot or if arts of your body are wet.
Do not carry out any cleaning or maintenance o eration without first deactivating the heater by setting the main system
switch to "OFF" and without first closing the fuel su ly.
Do not alter the safety and adjustment systems without rior authorisation and indications by the heater Manufacturer.
Do not ull, detach or twist the electric cables that exit the heater, even if the heater is not connected to the electrical
su ly.
Do not o en any doors that access the inside of the heater without turning the main system switch to "OFF".
Do not abandon or leave available to children the heater acking materials (cartons, nails, lastic bags, etc.), as these
are a otential source of danger.
Do not install the heater near flammable material, or in areas where there is a corrosive atmos here.
Do not lace any object on the heater or ush anything through the grilles in the casing nor in the flue ducts.
Do not touch the flue ducts as during normal o eration these can reach high tem eratures and re resent a risk.
Do not use any ada ters, multi le sockets and cable extensions for the electrical connection of the heater.
Do not install the heater in the o en air nor where it could be subject to atmos heric events.
Do not install the heater directly in limited s aces without adequate ventilation, as the burner air suction can create a
ressure dro in the room and consequently cause serious roblems.

DESCRIPTION OF THE HEATER
The warm air heater with fuel oil burner is a device that heats ambient air using thermal energy roduced by
combustion.
An airflow roduced by a centrifugal fan is in contact with the heat exchanger wall, so heat is exchanged with no
intermediate fluid. The combustion roducts, after losing heat, are ex elled. This system allows considerable reduction
of installation and o erating costs, and is articularly well suited to a lications where use of the heater is intermittent
or occasional. During the summer, the heater can also rovide ventilation only.
GENERAL CONSTRUCTION FEATURES
The most im ortant arts of the heater are:
•Comb stion chamber with flame inversion in stainless steel ty e AISI 430 resistant to high tem eratures, with low
thermal loading, of a ro riate sha e and volume.
•T be b ndle with oval section fire tubes and turbulence im rints to offer maximum heat efficiency.
•Fl e collector at the rear.
•Plen m for direct air diffusion with horizontal guide vanes, each se arately adjustable, on four sides.
•O ter casing consisting of removable anels in ainted steel sheet.
•Heat ins lation, anti-radiation, for the surfaces ex osed to radiation from the heat exchanger.
•Centrif gal fan, high erformance, with double air intake and low sound emission level.
The electrical system com rises:
Do ble thermostat Fan-Limit adjusted and electrically connected to offer the following functions:
•F nction “FAN” (25-35°C), controls the fan start u a roximately 60 seconds after ignition of the burner,
and sto s the fan at a roximately four minutes after the burner sto s. This avoids the emission of cold air on
start-u , and allows the accumulated heat in the heat exchanger to be removed, guaranteeing com lete
recovery before sto ing.
•F nction “LIMIT” (100°C), with Manual reset, sto s burner o eration if the air is overheated.
•Three way switch to allow heating, ventilation only in summer, and lant sto age.

HANDLING AND TRANSPORT
Handling must be done by ersonnel with suitable equi ment that has a lifting ca acity adequate for the weight of the
heater.
If a forklift truck is used, widen the forks as far as ossible. If a crane is used, hooking oints are the eyes laced at the
to of the heat exchanger.
Type 1÷4 Type 5÷7
ATTENTION
Trans ort and handling must be done very carefully to avoid damage to the heater and danger to ersons.
During trans ort and handling o erations, do not stand near the heater.
If heaters are to be stacked, you must not stack more than one heater on another. Make sure the stacks created
are stable by carefully aligning the ackages.
If a heater is to be moved by hand, make sure you have adequate ersonnel available with res ect to the weight
of the heater, as shown in the aragra h “TECHNICAL DATA”, and according to the route to be followed.
Wear rotective gloves at all times during these o erations.
POSITIONING
The lace of installation must be established by the lant designer or by a erson com etent in this field and must take
account of the technical requirements and of a licable Norms and Legislation, as usually s ecific authorisation are
needed (for exam le: urban lanning, architectural rules, fire safety, environmental ollution, etc.).
The necessary authorisations should therefore be obtained before installing the heater.
For correct installation remember that the heaters must:
•Be ositioned on a surface that is level, dry and able to carry the weight.
•Be ositioned so that the distances allow correct airflow and allow normal o erations of cleaning and
maintenance.
•Be at safe distances from flammable materials.
•Be near a chimney.
•Allow easy maintenance and control o erations.
•Be laced in areas with ventilation o enings according to a licable legislation.
Installation is NOT allowed:
•In laces where the atmos here is aggressive.
•In narrow s aces or where the heater sound emission could be am lified by reverberation or resonance.
•In corners where there may be de osits of dust, leaves or other materials that could reduce the efficiency of
the heater by obstructing airways.
•Outdoor.
•In laces with ressure dro conditions.

during trans ort of the heater with the lenum
dismantled.
For assembly after installing the lenum, roceed as
follows:
•Take the double thermostat out of the burner late
by unscrewing and sliding it out.
During extraction, ull out the thermostat (1)
carefully making sure it remains horizontal, thus
avoiding any twisting that could damage it.
•Insert the double thermostat in the s ecific hole
(2) at the to of the lenum and fasten it using the
screws su lied with the art.
•Fasten to the lenum the cable hose collars (3)
su lied with the unit.
•Fasten the electric su ly cable using the s ecific
cable hose collars (4) sited along the right hand
side of the heater.
The cable hose m st be stretched between
the collars so that it does not to ch hot parts

ELECTRIC CABLE ENTRY
The electric cables connecting the heater must be adequately rotected. To access the switchboard of the control anel,
roceed as follows:
•Remove the lower front anel (1) of the heater by
slackening the fastening screws.
•Remove the electric junction box cover (2) by
slackening the fastening screws.
•Insert the connection cables in the s ecific
grommets.
•To make the connections to the su ly line and to
the room thermostat, refer to the diagrams on
age 9.
•For the connections to the burner, refer to the
instructions for the burner ty e.
The section of the cables and the fuse
characteristics must be coherent with the TABLE
FOR ELECTRIC SUPPLY LINE SIZING shown above.
On com letion of the connection o erations, reassemble
in reverse order to the above descri tion.
Type 1÷7
The following points are comp lsory:
•Use a multi- ole automatic circuit breaker conforming to CEI-EN norms (contact a erture at least 3mm).
•Res ect the connection L (Phase) - N (Neutral).
•Protect and fasten adequately the electric cables.
•Avoid direct contact with hot surfaces on the heater.
•Make an effective earthing connection, making sure the earthing cable is slightly longer than the line cables so
that in the case of an accidental ull, the earthing cable will be the last to be detached.
The manufacturer cannot be considered res onsible for any damage caused by failure to connect the heater to
earth ground) and/or by failure to observe the rescri tions in the wiring diagrams.

DISCHARGE OF COMBUSTION PRODUCTS
The flue ducts and the connection to the chimney must be built in conformity with current a licable Norms and
legislation, using rigid ducting, being resistant to high tem erature and to mechanical loads, and gas tight. The correct
osition for the flue sam ling take-off is shown in the drawing.

The chimney must ensure the minimum de ression foreseen by current Technical Standards, considering zero
ressure at the connection between ducting and chimney (see table age 8).
Non insulated flue ducts are a otential source of danger.
Chimneys or flue ducts that are inadequately or badly dimensioned can am lify combustion noise levels and have
a negative influence on combustion arameters.
Joint seals must be made with materials that withstand tem eratures of at least 350°C (for exam le sealants,
mastics, silicone roducts).
Avoid or at least limit horizontal ducts that must in all cases be slo ed u wards.
Use ducts with smooth internal surfaces, in materials that can withstand high tem eratures and chemical
corrosion by combustion roducts, of diameter equal to or greater than the flange on the heater.
Avoid shar bends and section reductions.
Provide for a stub i e to allow flue sam ling.

INSTALLATION OF THE BURNER
For installing the burner, making the electrical
connections and carrying out the necessary adjustments,
refer to the instruction manual su lied with the burner.
We suggest that the fuel su ly lines be built according to
the figures here beside.
For oil versions an adequate filter must be rovided
in the fuel suction line.
