1 GENERAL RULES

This manual is an integral and essential part of this device and it must be carefully stored in its vicinity
for purposes of rapid consultation.

Read carefully the instructions and warnings provided herein because they provide important information
regarding safety, installation, use and maintenance.

In case of loss of the present manual, contact immediately the manufacturer.

ATTENTION!!

Being established that:

The "INFRA…ROSSO" ceramic heaters are heating according to the principle of visible radiation with
open air combustion.

The "INFRA…ROSSO" ceramic heaters have no chimney for the evacuation of exhausts outside, therefore
the combustion products remain in the premises mixed with the air. They will have to be ejected outside
by an adequate ventilation.

The ceramic plate of "INFRA…ROSSO" ceramic heater can reach temperatures of about 1.200 °C.

The "INFRA…ROSSO" ceramic heater need to be operated gas and electric energy.

The present manual does not indicate with absolute precision the type of places where these
equipments can be installed

For each installation, qualified personnel must evaluate the environment risk.

To make the installation easier , we strongly suggest to use the following basic suggestions:

The "INFRA…ROSSO" ceramic heater have to be installed in premises where there is absolutely no
risk of fire. The installation is forbidden in premises where gas or inflammable products are present or
where there is the risk that corrosive or inflammable gas could be generated.

The installation, control and maintenance of "INFRA…ROSSO" ceramic heaters have to be done in the
respect of laws, rules and good technique principles in force in the Country where the equipments are
installed.

The "INFRA…ROSSO" ceramic heaters have to be installed, verified and submitted to maintenance by
qualified personnel.

The "INFRA…ROSSO" ceramic heaters can be installed on a wall or on the ceiling, without any limit of
inclination, but with full respect of safety distances between the emitting source and the structure of the
building or the material present in the premises.

The premises where the "INFRA…ROSSO" ceramic heaters are installed will have to be
permanently ventilated in order to eject outside the combustion products. The minimum
ventilation admitted for the premises must respect the laws and the rules of the Country
where the installation is made.

The absence of ventilation in the premises is determining accumulation of CO2 and subsequently
carbon monoxide, which is a sign of bad functioning of "INFRA…ROSSO" ceramic heaters and
is very dangerous for the health of people and animals: in certain cases exhaust could be
cause of death for people and animals.

ATTENTION!

In the case the ceramic heaters are not compatible with the use, by the safety standpoint, we
invite you to consider our products INFRA B (airtight gas radiant tubes) and OHA (airtight gas
radiant strips).

2 EQUIPMENTS DESCRIPTION

2.1 General description

The "INFRA…ROSSO" ceramic heaters have to be considered as new generation products because
they are based on new innovating concepts : a pre-mix burner, the very high thermal performance, the
modularity of thermal power, the radiating performance, the highest flexibility of installation and use.

The "INFRA…ROSSO" ceramic heaters consist in

a) A steel chamber where takes place the mixing of air and gas.

b) A waterproof box containing the equipment, with the possibility of installation of air filters or
connection with a duct taking the air form outside. NEW !

c) Pre-mixed system of combustion, with a variable speed fan and modulating gas valve, working in
depression conditions. NEW !

d) Emitting source (burner) : a ceramic plate.

e) A standard stainless steel parabola reflector or (in option) a sandwich consisting inside in a
parabola reflector in aluminized and calorized steel with quartz finishing (e1) with high reflection and
infrared emission characteristics NEW !, a thermal isolating sheet (e2) NEW ! and an external parabola
in galvanized steel, for protection and isolation (e).

f) In the models …m (manual) the thermal power can be regulated manually with digital variation of
power within the modulation range of the model.

The thermal power modification can be by cable remote control, manual on the electric board or by
infrared remote control. NEW !

g) The centralized control of the heaters for the models …a (automatic) consist in the INET serial
network, with a regulation which is independent by the thermal power of each thermal zone, with the
integral proportional method (thermal power variation based on the established comfort temperature and
on the detected ambient temperature). NEW !

2.2 Functionning description

The "INFRA…ROSSO" ceramic heaters models are the following:

a) Mod. SCR 25 m with pre-mix combustion and manual variation of thermal power.

b) Mod. SCR 45 m with pre-mix combustion and manual variation of thermal power.

c) Mod. SCR 25 a with pre-mix combustion and automatic variation of thermal power by a InfraNet

control network and a Inet electric board (see specifications in the following paragraphs).

d) Mod. SCR 45 a with pre-mix combustion and automatic variation of thermal power by a InfraNet

control network and a Inet electric board (see specifications in the following paragraphs).

The functioning procedure of the over described models can be resumed in the following points :

A) The models …m (manual), with the digital PWM variator situated inside the equipment are regulated

at the factory during the final control before delivery to the thermal power requested (see table at
paragraph 2.3).

The demanded power will remain fix. If necessary it will be possible to modify the power according the
climate conditions of the moment, by the ground control board, using a linear potentiometer or by a
remote infrared control (optional).

The models …m (manual) with the remote control, will be programmed with the power requested by the
final user (see table at paragraph 2.3) and they will be controlled by a ON/OFF ambient thermostat.

Sequence of functioning of models …m (manual):

After the reception of the electric input, the lighting and start up procedure begins, with the following
steps :

1) The 577 DBC device starts the fan for the mixing chamber washing, for a minimum of 10 seconds.
The fan will start at the maximum speed, for a determined time, then it twill go down to the
programmed speed with the digital PWM variator.

2) When the washing stage is completed, the lighting discharge takes place for a minimum of ten
seconds (Ts 10) ; in the same time the gas valve 848 Sigma will be put in the open position by
electronic card.

3) The 848 Sigma gas valve will supply the gas at a pressure equal to the depression generated by
the fan (for instance fan depression 5 mbar > pressure delivered by the valve 5 mbar > pressure
read downstream the valve = 0).

4) The mixture generated inside the mixing chamber will be lighted on the ceramic plate. After a time
interval Ts the ignition discharge will stop and the electrode will switch automatically to the function
of flame detection.

If lighting will not take place or the flame will not be detected, the 577 DBC device, after a time interval
of 20 seconds, will make a second lighting attempt.

The equipment reset is of electric type with extinction and new lighting of electric supply.

5) The power at start up will be equal to the maximum power of the heater for the time interval
programmed in the PWM variator. After this lighting step, the thermal power of the heater will be
the one which will have been established (for instance : for SCR 25 m - programmed power PWM
20% - Start at 70% of PWM corresponding to 24 kW/h - After the start up time, the thermal flow
of the heater will be the one which will have been fixed PWM 20% = 12 kW/h).

B) The models…a (automatic) will be different from the manual models only by the standpoint of

control of the emitted power which in the manual models can be selected manually while in the
automatic models the thermal power is modulated by the master INET electric board (which is
outside the heater) as a function of the temperature detected in the ambient air, compared with
the established temperatures of manual models (SET POINT).

The master INET electric board, will change with the proportional integrated the fan speed and, as a
consequence, the gas flow and the emitted power.

The lighting sequence for the automatic models will be the one shown at the previous points 1-2-3-4.
