General Recommendations; Installation - Master BV 460E Instruction Manual

DESCRIPTION
BV MODEL space heaters have been designed for use in
small to medium-sized rooms and buildings where a fixed 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 flue. The
chimney or chimney flue must be big enough to guarantee
that the smoke is expelled efficiently.
The air which is used in combustion is aspirated directly
from the room or building which is being heated. It is therefo-
re of utmost importance that the room or building be properly
ventilated so that enough fresh air is circulating at all times.

GENERAL RECOMMENDATIONS

These heaters run with oil burners. Follow all local ordi-
nances and codes when using this heater.
Warning
Heater should be connected with a good earth
and via a differential switch.
• Make sure that this owner's manual is read and under-
stood before trying to operate and service this heater.
• Use only in places free of flammable materials.
• Have fire fighting 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 ope-
ration.
• Keep children and animal away from heater.
• Always separate heater from mains when not in use.
• Never fit heater with a different burner or increase burner
output over nominal power of heater as indicated on specifi-
cation adhesive.
• Never block air inlet or outlet since this couid lead to
ventilation motor overload and consequently to overheating of
unit.
Warning
Only the burners which are chosen and supplied
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, automatical-
ly stops the burner if the flame goes out. The Overhrat
Thermostat, L2, 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, RM, 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
OBSERVED FAULTS, CAUSES AND REMEDIES).
Overheat safety thermostat, L1, shuts down the heater if
air flow is not sufficient 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
qualified personnel only.
Electrical connections and settings
Every space heater is supplied along with the safety and
control devices which are indispensable to the correct func-
tioning of the unit. The electric switchboard, burner, the fan
thermostat, overheat safety thermostat and the overheat ther-
mostat with manual restart have already been connected.
Warning
The mains supply to the heater must be earthed
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
7 and 8.
Having completed all these operations check carefully
that all electrical connections correspond to the wiring dia-
gram and check the setting of thermostat F (cf. Technical
Specifications). When the heater is first turned on you must
check that the fan does not use more current than the maxi-
mum permitted limit. Finally, to regulate the burner follow the
instructions in the Burner Instruction Manual.
