DESCRIPTION
Warning: During use, two of the four sides must be left open so as to avoid overheating of the combustion chamber.
BG space heaters have been designed for use in small to me-
Heat is produced by combustion and the heat from the smoke is transmitted to the fresh air through the metal walls of the combu- stion chamber and the heat exchanger. Smoke circulates twice in this type of combustion chamber.
Air and smoke pass through separated ducts, both of which are welded and sealed. When, after combustion, the waste gases have cooled down, 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 therefore of utmost importance that the room or building is properly ventilated to guarantee the continual circulation of enough fresh air.
The air head has four lateral openings and adjustable fins which send the hot air in the desired direction (Fig. 1).

BG heaters can operate with burners thatare fuelled by heating oil, methane (G20) or LPG (butane G30 andpropane G31) of the
There are three safety devices which are activated in case of se- rious malfunction. The Burner Control Device, which is mounted on the burner and has a restart button, automatically stops the burner if the flame goes out. The Overheat Thermostat, L, of the manual restart type, is activated if the temperature of the com- bustion 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 using more electric 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 up again (“OBSERVED FAULTS, CAUSES AND REMEDIES”).
GENERAL ADVICES
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 will no longer comply with CE regulations.
The space heater must be installed, set up and used in accor- dance with existing laws.
Here are a few general guidelines which should be followed: •Follow the instructions in this booklet very carefully.
•Don’t install the heater in places where there may be a risk of fire or explosion.

•Inflammable material should be kept at a safe distance from the heater (Minimum 3 meters).
•All fire prevention regulations must be adhered to.
•The room or building that is being heated must be sufficiently ventilated so that the heater has enough air to function pro- perly.
•The heater must be near a chimney or chimney flue and a sui- table electric switchboard.
•Don’t let animals or children near the heater.
•After use make sure the disconnecting switch is off.
When using any type of space heater it is obligatory:
•not to exceed the maximum level of heat output of the furna- ce.
•to make sure that there is adequate air circulation and air sup- ply to the heater and that nothing is obstructing the aspiration and expulsion of air. Movement of air may be obstructed in various ways including placing covers or other objects on the heater or positioning the heater too near a wall or other large object. If there is insufficient air supply the combustion cham- ber overheats and the overheat thermostat with manual restart is activated.
INSTALLATION
Warning: Qualified personnel must carry out the following operations.
REMOVAL OF THE PALLET
To remove the space heater from the pallet on which it is atta- ched for the transport, unscrew the fixing screw of the inferior panel and lift the machine with a suitable mean of lifting using the four points (a) (Fig. 2).

Every space heater is supplied along with the safety and control devices which are indispensable to the correct functioning of the unit.
The electric switch board, the fan thermostat and the overheat thermostat with manual restart have already been connected. The following operations must now be carried out:
