General Advice - Master BF 35 Manual De Instrucciones

WARNING: To avoid an overheating of the combustion chamber the fins must never be completely
closed. For this reason a blocking bar prevents the complete closure of the fins.
BF space heaters have been designed for use in medium to big sized rooms and buildings where a fixed heating
system is needed.
Heat is produced by combustion and the heat from smoke is transmitted to fresh air through the metal walls of the
combustion chamber and the heat exchanger. The combustion chamber is of the type where smoke follows a
course of two modules.
Air and smoke pass through separated ducts, both of which are welded and sealed. When, after combustion, the
waste gases have cooled, they get expelled through a duct that has to be connected to a chimney or chimney flue
which must be big enough to guarantee that smoke gets efficiently expelled.
Air used for combustion gets aspirated directly from the room or building that is being heated. It is therefore very
important the room or building to be properly ventilated so that there is enough fresh air circulating at all times.
Hot air can be sent in the desired direction by moving the fins on the air head.
BF heaters can operate with ON-OFF type and fuelled by heating oil burners. Where burners use oil, a front
attached fuel tank is provided (4). There are two safety devices which are activated in case of serious
malfunctioning. The burner control device, which is mounted on the burner and is provided with a restart button
that automatically stops the burner if the flame turns off, while the manual restarting type overheat thermostat
activates if the temperature of the combustion chamber reaches the set maximum limit.
If any of those safety devices are activated, you should check carefully what the problem is before pressing the
restart button and restarting the heater (check the "FUNCTIONING PROBLEMS: CAUSES AND SOLUTIONS"
paragraph).
WARNING: Only chosen and by the manufacturer supplied burners can be used. If another type of
burner is used, the heater no longer complies with the CE regulations.
The space heater has to be installed, set up and used in accordance with existing laws. Here are a few general
guidelines which should be followed:
•
Follow the instructions of this manual very carefully.
•
Don't install the heater in places where there might be risk of explosion or fire.
•
Flammable material should be kept at a safe distance from the heater (3 meters minimum).
•
All fire prevention measures have to be enforced.
•
The room or building to heat has to be sufficiently ventilated so that the heather disposes of the needed ait
to work properly.
•
The heater has to be near a chimney or a chimney flue and a suitable electric switchboard.
•
Don't let any children or animal get near the heater.
•
After use, make sure that the disconnecting switch if off.
When using any type of space heater, it is compulsory to:
•
Not exceed the maximum furnace heat output level.
•
Make sure that a proper air circulation and supply is provided and that nothing might obstruct the air
aspiration and expulsion: that can be caused, for example, by placing covers or other objects on the
heater, or by positioning it too close to walls or other large objects. If there is an inadequate air supply,
the combustion chamber might start overheating, getting the overheat thermostat to intervene.
