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).

2.2 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.

6.2 Fan digital PWM regulator
The fan speed is fixed by the digital regulator situated inside the equipment box.
For each model the manufacturer is programming the minimum and maximum value of PWM which will determine the minimum and maximum thermal power of the ceramic heater (for instance : PWM minimum 25% = 12 kW
- PWM maximum 60% = 24 kW) with no possibility of modification by the final user. In this interval, it's possible to choose the requested thermal power, fixing a value, acting on the digital regulator situated inside the equipment box.
For operational needs, it's possible to modify the thermal power from a place accessible by the operator by a 10 K potentiometer (optional) connected to the contact 1 and 2 of digital regulator, at a maximum distance of 15 m.
To fix the thermal power, the digital PWM regulator must be used. In order to modify the thermal power press SET, find the percent desired value using the arrows up and down and confirm pressing SET.
Attention!
The percent maximum value which is fixed corresponds to the maximum thermal power of the heater and the percent minimum value of PWM corresponds to the minimum thermal power of the heater.
THE FIXED PWM VALUES ARE UNCHANGEABLE AND THEY CAN BE MODIFIED ONLY AND EXCLUSIVELY BY THE MANUFACTURER
DIGITAL PWM PROGRAMMING
1) Press at the same time the switch UP and DOWN (switches avec the arrows) for a few seconds.
2) Select with the switches the parameters to be modified
3) Press SET, modify the parameters, press SET to go out
