BASIC SAFETY RULES
We remind you that the use of products needing electrical energy, gas or heating oil requires the observanc e of some
basic safety rules, including the following:
The unassisted use of air heaters by children or
disabled people is forbidden.
Electrical devices or equipment such as
switches, domestic appliances etc. must not be
used if there is a smell of fuel or unburnt gases
etc. In such cases:
Ventilate the room by opening doors and
windows;
Close the fuel shut-off;
Call the DESA ITALIA Technical Assistance
Dept. or other professionally qualified
personnel.
The equipment must not be touched being
barefeet of with wet or damp parts of the body.
Cleaning and maintenance operations on the
equipment must be carried out only when it is
switched off with the main electrical switch if the
‘off’ position, and with the fuel supply cut off.
It is forbidden to interfere with or alter the safety
or regulatory systems without prior authorisation
and without following the manufacturer’s
instructions.
It is forbidden to pull or twist the electric cables
coming out from the equipment, even if the
equipment is disconnected from the main
electricity supplies.
Before entering the access doors to the internal
parts of the equipment, the main switch must be
turned to ‘off’.
It is forbidden to throw away, abandon or leave
the packaging material (cardboard, fasteners,
plastic bags etc.) within the reach of children, as
they may be a source of danger.
It is forbidden to install the equipment near
to flammable materials or where there are
aggressive agents in the atmosphere.
It is forbidden to put objects on top of the
equipment or push them inside the boy shell grill
and exhaust discharge dust.
The exhaust flue must not be touched as it may
reach temperatures which are dangerously h igh
to the touch during normal working.
It is forbidden to use adapters, multiple sockets
and extension cables for the equipment
electrical connection.
It is not permitted to install the equipment
outdoors or in any place where it will be subject
to atmospheric agents.
It is forbidden to directly install the equipment in
restricted rooms with no fitting ventilation since
the air aspiration might cause a strong
depression inside the room, leading to serious
inconveniences.

DESCRIPTION OF THE EQUIPMENT
The BI equipment is designed to heat the air in the room using heat en ergy produces by combustion. Essentially the
equipment consists of heat exchanger assemblies exchanging heat from the combustio n by-products from a forced gas
or heating fuel oil burner by a high performance fan assemb ly. The air to be heated is aspired by the latter and flows
against the heat exchange where its temperature rises to then be distributed either immediately or via suitable
channelling. The particular features of the centrifugal fan make the equipment well sui ted for installation where hot air
needs to be distributed through channels or generally where it is necessary to have static pressure available. A special
flange (both on inlet and outlet) enables the equipment to be connected up the channelling.
This system gives a notable reduction in the costs of the plant and also works economically, making itself particularl y
suitable where it is expected it be used intermittently or oc casionally. The equipment is designed so that it can also be
used to provide ventilation only during the summer months.
GENERAL STRUCTURE FEATURES
Heat exchanger
Built with welded steel and steal-tested in accordance with t he UNI-CIG 9462 standar ds, i t is eas y to be i nspected for the
normal cleaning and maintenance operations. It consists of:
Combustion chamber in low thermal load stainless steel with suitable shape and size;
Exchange elements in stainless steel, with modular, large surface sections with swirl impressions for an optimal heat
exchange;
Exhaust manifolds in fine steel.
External casing
The external casing consists of removable panels in pre-painted steel and also includes:
Insulation of the surfaces exposed to radiant heat from the heat exchanger;
Delivery air flange for connection to the hot air distribution circuit;
Intake guard with flanges for connection to the intake circuit.
Fan assembly
One or more high performance centrifugal fans producing low noise emissions. These are run by electrical motors
connected to a pulley and belt system. The motor has got an adjustable pulley (type 1 to type 10) which means the
system can be easily adapted to the particular needs of the customer’s premises.
Control and safety thermostats
The heater has a dual thermostat which is calibrated and electrically connected to perform the following functions:
"FAN" function (25-35°C, FAN thermostat) - controls fan start up about 60 seconds after burner ignition and stops
the fan about 4 minutes after the burner has stopped. This prevents unpleasant cold air being conveyed into the room
on start up und utilises the stored heat in the heat exchangers after the burner has been switched off.
“SAFETY” function (type 5 to 15, TR thermostat) – preset at 80°C, it has th e function of stopping the bruner in
case of anomalous overheating of the air. Automatic reset, the correct setting has to be set during the first stat-up.
"LIMIT" function (sealed setting 100°C, LM thermostat) – manual reset, switches the burner off in case of
overheating of the air.
Fume discharge outlet
The equipment has a circular outlet to which a metal exhaust pipe can be connected and safely joined.

HANDLING AND TRANSPORTATION
Moving the equipment must be carried out by properly equipped personnel with equipment which is suitable for the
weight of the heater. If a fork lift is used, the equipment should be taken up at the bottom using the guides in the
supporting base. If a crane is employed use the eye-bolts at the top of the heat exchanger to lift the equipment.
Type 110
Type 1115
WARNING!
Handling and transportation must be carried out with the greatest care to avoid damage the equipment and putting
people in danger.
It is forbidden for people to stand close to the equipment during handling and trans portation manoeuvres.
It is forbidden to stack more pieces of equipment than the indication on the pack aging itself and the greatest care must
be taken in aligning the packages so that they are stable.
If the equipment must be moved by hand, ensure that sufficient human strength is available for the task in relation to t he
weights indicated in the paragraph “TECHNICAL DATA” and to where and how far the equipment has to be moved.
The use of protective gloves is advisable.
11
LOCATION
The place of installation must be established by the plant project engin eer or competent person and must take account of
the technical requirements and current legislation and regula tions which demand the obtaining of an authorisation (e.g.
building, architectural and fire regulations, environmental legislation and so on). Before installing the equipment it is
therefore advisable to apply for and obtain all the necessary authorisations.
To be correctly installed, the BI series heater has to satisfy the following:
Be placed on a level surface which is able to support its weight;
Observe the distances indicated in this manual so that there is a proper air flow and the normal cleaning and
maintenance operations can be properly carried out;
Maintain the safety distances from flammable materials;
Be easily connected to a flue;
Be easily connected uo to the fuel tank;
Be near to an electrical socket;
Allow easy carrying out of maintenance and monitoring ope r ations;
Have the openings and ventilation required by the law in force.
The installation is not advisable:
In aggressive atmosphere rooms;
In tight rooms where the sound level of the heater might be amplified by reverberations or resonances;
In coins where it might settle leaves or anything else might obstruct the air flow, reducing the equipment efficiency;
Outside;
In depressed rooms.
WARNING!
The hot air generators types 11 to 15 are, for ease of transport, shipped in t wo separated sections (base and body). To
install, proceed as follows:
Position the base so that the electrical panel is on the same side as the burner;
Mount the centring pins provided on the upper part of the base;
Place the body over the base making sure that the two frames are perfectly aligned.
FUEL CONNECTION
The oil connection must be carried out by the authorised and qualified personnel who must follow the indications in the
manual strictly as well as the law currently in force.
FLUE
The fume channel and connection to the flue must be in acc ordance with the law and regulations currently in force, using
rigid pipes resistant to mechanical, thermal and chemical stresses resulting from combustion. Recommendations:
Avoid or at least limit the horizontal stretches which must in any case tend in an upward direction;
Use piping with smooth inner surfaces made from a suitable material which is resistant to the thermal and chemical
stresses caused by combustion, with a diameter equal to or larger than that of the connector on the equipment it self;
Avoid sharp bend and diameter reductions;
Place in the system a well for taking samples for analyses of the combustion by-products.
The chimney has to ensure the minimal depression previe wed by the Regulations in force, considering as “zero” the
pressure at the flue connection (see chart page 8).
The non-insulated discharge channels might be a source of danger.
Unfitting or badly dimensioned flues or discharge channels might amplificate the combustion sound level and
negatively affect the combustion parameters.
The tightness of the joints has to be realized with materials resistant at temperature of at least 350° C (e.g. filler,
mastic, silicones preparations).
