DESCRIPTION

JUMBO 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 therefore of utmost im-

portance that the room or building be properly ventilated so that

enough fresh air is circulating at all times.

The air heads can be replaced by heads of the following types:

• a head with two or four openings, all of which must be kept

open.

• a head of the “plenum” type with four lateral openings and ad-

justable fins which send the hot air in the desired direction

(Fig.1).

Warning

During use, two of the four sides must be left open so as

to avoid overheating the combustion chamber.

Jumbo heaters can operate with burners that are fuelled by heating

oil, methane (G20) or L.P.G. (butane G30 and propane G31) of the ON-OFF

type.

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 seri-

ous 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 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 permit-

ted limit; the warning light (10) lights up and the heater stops working.

If any of these safety devices are activated you should check care-

fully what the problem actually is before pressing the restart button

and starting the heater off again (“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 (The

lamp (9) lights up and then it cuts down).

GENERAL ADVICES

The space heater must be installed, set up and used in accordance

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 which is being heated must be sufficiently

ventilated so that the heater has enough air to function properly.

• The heater must be near a chimney or chimney flue and a suit-

able 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 furnace

(“TECHNICAL SPECIFICATION TABLE”);

• to make sure that there is adequate air circulation and air supply

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 the

airflow is not adequate, the combustion chamber will overheat

and the overheat safety thermostat L1 will turn the burner off

and on continnously (“OBSERVED FAULTS, CAUSES AND

REMEDIES”).

INSTALLATION

Warning

The following operations must be carried out by quali-

fied personnel only.

ELECTRICAL CONNECTIONS AND SETTINGS

Every space heater is supplied along with the safety and control

devices which are indispensable to the correct functioning of the unit.

The electric switchboard, burner, the fan thermostat, overheat safety

thermostat and the overheat thermostat with manual restart have al-

ready 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 de-

tails electricity supply characteristics (Tab.1). Tab. 2 shows the

adhesive label on units which have three-phase supply;

• The burner must be connected to the fuel supply (Burner In-

struction Manual).

• Connect the burner to the electricity supply with the burner plug.

• 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 (13).

Having completed all these operations check carefully that all

electrical connections correspond to the wiring diagram. When the

heater is first turned on you must check that the fan does not use more

current than the maximum permitted limit. Finally, to regulate the burn-

er follow the instructions in the Burner Instruction Manual.
