IDENTIFICATION OF PART "DI"
Series DI is a line of hot air generators with indirect heating
system. These generators have a heat exchanger that enables
to separate exhaust combustion gases from the heat released in
the environment, so that it is possible to inject a fl ow of clean hot
air in the area that needs to be heated and to discharge exhaust
fumes externally.
Serie DI hot air generators is designed in compliance with
current safety, performance and life standards, is fi tted with
safety devices confi gured to guarantee continuous operation,
minimize noise and are manufactured in carefully selected
materials that ensure maximum reliability.
SAFETY INFORMATION
WARNING
IMPORTANT: Read the manual carefully before attemp-
ting to assemble,switch on or service this heater. The use
of the heater may cause serious or fatal injuries resulting
from burns, fi re, explosion, electrical discharge or carbon
monoxide poisoning.
DANGER:Carbon monoxide poisoning can be fatal!
Carbon monoxide poisoning The fi rst symptoms of carbon
monoxide poisoning are similar to those of fl u, with headache,
dizziness and/or nausea.These symptoms may be caused by
the defective functioning of the heater. Go outside into the open
air immediately! Have the heater repaired. Some people feel
the effects of carbon monoxide to a greater extent, especially
pregnant women, those suffering from anaemia, cardiac or lung
conditions, those who are drunk and anyone at a high altitude.
Ensure that you have read and understood all the warnings.
Keep this manual for future reference - it is a guide to the safe
and correct functioning of the heater.
• Use only fuel oil no.1 in order to avoid the risk of fi re or explo-
sion. Never use petrol, naphtha, paint solvents, alcohol or other
highly infl ammable combustibles.
• Fuelling
a) The individual responsible for fuelling the heater must have
the relevant competence and be completely familiar with the
manufacturer's instructions and with current norms concer-
ning the safe fuelling of the heaters.
b) Only use the type of fuel expressly specifi ed on the identifi ca-
tion label of the heater.
c) Before adding fuel, extinguish all fl ames, including the pilot
light, and wait until the heater has cooled down.
d) While adding fuel, inspect all the fuel lines and joins to make
sure there are no leaks.
Any leak whatsoever must be repaired before switching on
the heater.
7
e) In no circumstances must more than one day's supply of
7
fuel be stored in the same building in proximity to the heater.
7
Fuel storage tanks must be kept in a separate location.
8
f) All fuel tanks must be kept at a minimum distance from hea-
8
ters, oxyacetylene torches, welding equipment etc. (with the
8
exception of the fuel tank incorporated into the heater) fol-
8
lowing regulations.
9
g) Wherever possible, fuel should be stored in a place where
9
the fl oor does not allow fuel to seep through and drip onto live
10
fl ames beneath, which might cause fi re.
h) Fuel must be stored in compliance with current norms.
• Never use the heater anywhere where petrol, paint solvents or
other highly infl ammable vapours are present.
• While using the heater, follow all local ordinances and current
norms.

These materials should be fi xed safely so as to ensure that
they do not catch fi re and are not blown by the wind.
• Only use in locations where there are no infl ammable fumes or
high concentrations of dust.
• Power the heater only with electric power that has the voltage,
frequency and number of phases specifi ed on the identifi cation
label.
• Only use earthed three-wire extension cords.
• In order to avoid the risk of fi re, make sure the heater is on a
fi rm, fl at surface when it is being used or is hot.
• When moving or storing the heater, keep it level to avoid fuel
loss.
• Keep children and animals away from the heater.
• Disconnect the heater from the mains supply when not in use.
• When controlled by a thermostat, the heater may come on at
any moment.
• Never use the heater in frequently used rooms or in be-
drooms.
• Never obstruct the air intake (rear end) or the air output (front
end) of the heater.
• When the heater is hot, connected to the mains supply or in
use, it must never be moved, handled, fi lled up with fuel or
serviced in any way.
STARTING THE HEATER
Before turning on the heater and therefore before attaching it
to the mains power supply, check that the characteristics of the
mains power supply are the same as those indicated on the
identifi cation label.
WARNING:The electric power cable of the heater must
be earthed and must have a differential magnetothermal
switch.The electric plug must be connected to a socket
which has a disconnecting switch.
To turn on the machine, do the following:
• Flip switch 1 (Fig. 2) to the position with the symbol: ON - the
fan comes on and after several seconds the heater starts bur-
ning.
The fi rst time the heater is used, or after the fuel circuit has been
completely drained, the fl ow of fuel oil to the nozzle may be in-
