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.
INSTALLATION WARNING! The following operations must be carried out by qualified personnel only. ELECTRIC CONNECTIONS AND SETTINGS: WARNING! The main heater electricity supply has to be provided with grounding and a magneto-thermal switch with a differential. The power wire has to be connected to a switch board linked to a disconnecting switch.
SWITCHING ON To start the heater: • Set the commutator (1) in the “O” position. • Turn the disconnecting switch on the electric board on. • Set the room thermostat (2) at the maximum level and set the commutator (1) in the position: the burner will start and, after the combustion chamber has begun to heat, the fan will start too.
