DESCRIPTION
BV MODEL
space heaters have been designed for use in small
to medium-sized rooms and buildings where a
fi
xed or mobile
heating system is required.
Heat is produced by combustion and the heat from the smoke
is transmitted to the fresh air through the metal walls of the
combustion chamber and the heat exchanger. The
combustion
chamber is of the type where smoke circulates twice.
The air and smoke pass through separated ducts, both of which
are welded and sealed. When, after combustion, the waste
gases have cooled, they are expelled through a duct which
must be connected to a chimney or chimney
fl
ue. The chimney
or chimney
fl
ue must be big enough to guarantee that the smoke
is expelled ef
fi
ciently.
The air which is used in combustion is aspirated directly from the
room or building which is being heated. It is therefore of utmost
importance that the room or building be properly ventilated so
that enough fresh air is circulating at all times.
GENERAL ADVICE
WARNING: Heater should be connected with a good ear-
thand via a differential switch.
These heaters run with oil burners. Follow all local ordinances
and codes when using this heater.
• Make sure that this owner’s manual is read and understood
before trying to operate and service this heater.
• Use only in places free of
fl
ammable materials.
• Have
fi
re
fi
ghting equipment available.
• Use only in well vented areas and have a fresh air supply
adapted to the heater requirements.
• Locate heater permanently on a stable surface.
• Check heater before starting and regularly during operation.
• Keep children and animal away from heater.
• Always separate heater from mains when not in use.
• Never
fi
t heater with a different burner or increase burner out-
put over nominal power of heater as indicated on speci
fi
cation
adhesive.
• Never block air inlet or outlet since this cou
l
d lead to ventilation
motor overload and consequently to overheating of unit.
WARNING: Only the burners which are chosen and sup-
plied
by the manufacturer can be used. If another type of
burner is used the heater no longer complies with CE
regulations.
There are three safety devices which are activated in case
of serious malfunction. The Burner Control Device, which is
mounted on the burner and has a restart button, automatically
stops the burner if the
fl
ame goes out. The Overh
e
at Thermostat,
TS, of the manuel restart type, is activated if the temperature
of the combustion chamber rises above the set maximum limit;
the warning light (9) lights up and the heater stops working. The
Thermal Relay, RT, is activated if the fan motor starts to use
more electrical current than the maximum permitted limit; the
warning light (10) lights up and the heater stops working.
If any of these safety devices are activated you should
check carefully what the problem actually is before pressing
the restart button and starting the heater off again (cfr.
OBSERVED FAULTS, CAUSES AND REMEDIES). Overheat
safety thermostat, TSS, shuts down the heater if air
fl
ow is not
suf
fi
cient to cool off combustion chamber: the heater will restart
automatically as soon as the heater has cooled down enough.
INSTALLATION
WARNING: The following operations must be carried out
by quali
fi
ed personnel only.
ELECTRICAL CONNECTIONS AND SETTINGS.
WARNING: The mains supply to the heater must be ear-
thed and have a magneto-thermal switch with differential.
The power cord must be connected to a switch board
which has a disconnecting switch.
The following operations must now be carried out:
• Plug in the power cord having read the adhesive label which
details electricity supply characteristics.
• Connect accessories such as the room thermostat or clock to
the unit’s electric switchboard: electric wire must be connected
by means of the cable fastener (8) to the terminals.
Having completed all these operations check carefully that all
electrical connections correspond to the wiring diagram and
check the setting of thermostat TV (cf. Technical Speci
fi
cations).
When the heater is
fi
rst turned on you must check that the fan
does not use more current than the maximum permitted limit.
Finally, to regulate the burner follow the instructions in the
Burner Instruction Manual.

CONNECTION TO HOT AIR DUCTS
The heaters can be delivered with following accessories: 4-way
air outlet cones.
The new head with the exception of the “plenum”, may be con-
nected to new air ducts if the user wishes to satisfy speci
fi
c
needs. In this case and in particular if the diameter and length
of the ducts have been changed or if the number of bends has
been modi
fi
ed, air output may vary. Consequently it is very im-
