1 GENERAL RULES
This instructions booklet is an integral part and essential
of the appliance and must be kept with care near the
appliance for all future consultation.
Read the instructions and warnings in this booklet care-
fully, as they supply important indications for safety,
installation, use and maintenance.
ATTENTION ! !
If you lose this booklet, contact the manufacturer imme-
diately.
The appliance has been built for heating large work
environments such as industrial and handicrafts sheds
in general, warehouses, premises with large-scale air
renewal, loading bays outside sheds, environments for
sports activities (gymnasiums), by means of the princi-
ple of thermal radiation; this allows the heating of single
specific area and, if suitably combined with other
appliances, heating of the whole environment. It may be
used for heating premises for zootechnical uses (poultry
and swine farms) and for agriculture (greenhouses) and
in all those industrial production cycles (ovens) in which
heating is needed without there being any contact bet-
ween the product and the combustion fumes.
It is not allowed to use the appliance to heat premises
intended for handicraft or industrial activities in which
the processes carried out and the materials stored invol-
ve a risk of the formation of gas, vapours or dust which
could cause fire or explosions.
The appliance must be installed by professionally quali-
fied personnel, responsible for compliance with the
safety regulations in force. The manufacturer declines
all responsibility in the event of damage due to incorrect
installation or to improper and/or incorrect use of the
appliance.
The packing material (nylon, polystyrene foam, wood,
staples, etc.) must not be left within the reach of chil-
dren, as they are potential hazards.
The appliance must be started up for the first time by
qualified personnel.
In the event of stopping and/or malfunction of the
appliance, switch it off. Any repairs or replacement of
components must be carried out exclusively by skilled
personnel, using only original spare parts. Failure to
abide by these rules may be detrimental to the safety of
the appliance.
To guarantee good operation of the appliance it is indi-
spensable to follow scrupulously the indications given
by the manufacturer and to have maintenance carried
out on the appliance by skilled personnel (at least once
a year).
2 PACKING
2.1 Packing list
a) The exhaust fan is delivered in a cardboard box.
b) The burner is delivered in a cardboard box with the
Instruction Manual.
c) Brackets, springs to fix the reflectors, a small
bag with the screws to connect brackets and
radiant tubes are delivered in a cardboard box.
d) The radiant pipes required for each INFRA radiant
heater are packed separately, with all the neces-
sary connections and sleeves in a cardboard box.
e) The reflectors are supplied packed one of the top
of the other, to save space.
,,ATTENTION! Remove any protective plastic film
from the hoods before fitting them onto the brac-
kets.

3 GENERAL TECHNICAL CHARACTERISTICS
3.1 Description and characteri-
stics of operation
The "INFRA" sealed diesel fired radiant combustion
tube is made of aluminized tube, in a U shape, combu-
stion takes place inside the tube through a mixture of
vaporized fuel and air, bringing the outside surface to an
average temperature of about 350°C. The steady ope-
ration temperature is reached in a few minutes. The
control, mixing, combustion and ignition are enclosed in
a container, installed in the head of each module.
Above the whole length (6, 9, 12 m) of the radiating tube
there is a mirror surface, with the purpose of reflecting
down the heat radiation produced by the tube itself. This
surface may also be provided with rock wool insulation
on the top part (the so-called RBT version). The control
of the conditions of comfort inside the environment is
assigned to the infrared-sensitive thermostats located in
the immediate vicinity of the work area and placed on an
electric panel which can switch on and off one or more
modules at the same time. This offers the possibility of
heating either the whole environment or individual
areas, even at different temperatures.

Example of
protection
of the
motor of a
bridge
crane
Combustible materials in store must be at a sufficient
distance for the radiating pipe to prevent them from rea-
ching dangerous temperatures. Laboratory experiments
have shown that combustible materials (with a surface
of 0.5 m2), placed at a distance of 1.5 metres from the
module and parallel to it, never reach temperatures that
4 INSTALLATION
could be considered dangerous. In particular cases, if it
is impossible to respect these distances (for example
motors of the carriages on a bridge crane, electric
cables, lamps, cabins) suitable steps must be taken to
screen heat-susceptible materials from the module heat
radiation (see Draw 16).
MINIMUM DISTANCES OF COMBUSTIBLE
MATERIALS FROM THE HEAT RADIATING TUBE
(wood, cardboard, plastic materials, pallets, etc.)
ACCORDING TO:
- STANDARD DIN 3372 part 6, par. 3.12
- DVGW, G63/11, part 12/3.1.2
In any case the distance must be such that the maxi-
mum surface temperature of the materials does not
exceed 85°C.
The bearing elements must not be heated on large
surfaces to over 50°C.
1) Reflecting parabola
2) Heat radiating tube
3) Insulation (rock wool 3 cm thick)
4) Protecyive plate (stainless steel, galvanised plate,
aluminium)
5) Plate support must allow air passage for ventilating
the motor
6) Eletric motor
7) Bridge crane

4.2 Assembly of the unit
To assembly the various components of INFRA radiant
tubes, follow the instructions provided below
4.2.1 INFRA 6G assembly
Begin assembly of the tube, starting with the bend:
1) Fit the two tubes (delivery and return) into the bend
for about 120 mm (Draw 14), hammering slightly if
necessary, taking care to place a piece of wood
between the hammer and the sleeve (see Draw
15). Then fix them in place, using the screws sup-
plied with the bend
2) Assemble the connecting collar Ø 108 mm and the
other delivery tube (Draw 14), fixing them with the
screws supplied, taking care to push the tubes half
way into the collar (about 150 mm), hammering
slightly if necessary, taking care to place a piece of
wood between the hammer and the sleeve (see
Draw 15).
,,ATTENTION: Fit the tube taking care that the
end with adhesive tape is positioned at the
opposite extremity to the sleeve.To correctly
assemble the tube refer to the exploded view
(Draw 4) and to the table 2.
