Riello RS150/M Burner For Heating industry
The burners have been designed and built in compliance with current regulations and directives, applying the known technical rules of safety and envisaging all the potential danger situations. It is necessary, however, to bear in mind that the imprudent and clumsy use of the equipment may lead to situations of death risk for the user or third parties, as well as the damaging of the burner or other items. Inattention, thoughtlessness and excessive confidence often cause accidents; the same applies to tiredness and sleepiness.
It is a good idea to remember the following:
³ The burner must only be used as expressly described. Any other use should be considered improper and therefore dangerous.
In particular:
it can be applied to boilers operating with water, steam, diathermic oil, and to other users expressly named by the
manufacturer; the type and pressure of the fuel, the voltage and frequency of the electrical power supply, the minimum and maximum deliveries for which the burner has been regulated, the pressurisation of the combustion chamber, the dimensions of the combustion chamber and the room temperature must all be within the values indicated in the instruction manual.
³ Modification of the burner to alter its performance and destinations is not allowed.
³ The burner must be used in exemplary technical safety conditions. Any disturbances that could compromise safety must be quickly eliminated.
³ Opening or tampering with the burner components is not allowed, apart from the parts requiring maintenance.
³ Only those parts envisaged by the manufacturer can be replaced

Describle of Burner
Burner Head
RS series burners can choose combustion heads of different lengths according to different needs. The selection is based on the thickness of the front plate of the boiler and different types of boilers. Depending on the heat user, check that the combustion head is correctly installed in the combustion chamber. Flange-mounted screws can be easily adjusted to adjust the internal position of the burner head for full the maximum output of the burner.
The user is the person, body or company that has acquired the machine and intends to use it for the specific purpose. He is responsible for the machine and for the training of the people working around it.
The user:
³ undertakes to entrust the machine exclusively to suitably trained and qualified personnel;
³ must take all the measures necessary to prevent unauthorised people gaining access to the machine;
³ undertakes to inform his personnel in a suitable way about the application and observance of the safety instructions.With that aim, he undertakes to ensure that everyone knows the use and safety instructions for his own duties;
³ must inform the Manufacturer if faults or malfunctioning of the accident prevention systems are noticed, along with
any presumed danger situation.
³ Personnel must always use the personal protective equipment envisaged by legislation and follow the indications given in this manual.
³ Personnel must follow all the danger and caution indications shown on the machine.
³ Personnel must not carry out, on their own initiative, operations or interventions that are not within their province.
³ Personnel must inform their superiors of every problem or dangerous situation that may arise.
³ The assembly of parts of other makes or any modifications can alter the characteristics of the machine and hence
compromise operating safety. The manufacturer therefore declines any and every responsibility for any damage that
may be caused by the use of non-original parts.

Installation:
Securing the burner to the boiler
Before fixing the burner to the boiler, check from the opening of the blast tube that the probe and the electrode are
correctly positioned, as in Fig. 12.
If, in the previous check, the position of the probe or electrode was not correct, remove the screw 1)(Fig. 13), extract
the inner part 2)(Fig. 13) of the head, and adjust them.
Do not rotate the probe: leave it as in Fig. 12 since if it is located too close to the ignition electrode, the control box
amplifier may be damaged.
Separate the combustion head from the rest of the burner, Fig. 11. To do this, proceed as follows:
- loosen the 4 screws 3) and remove the hood 1);
- disengage the articulated coupling 7) from the graduated sector 8);
- remove screws 2) from the two slide bars 5);
- remove the 2 screws 4) and pull the burner back on slide bars 5) by about 100 mm;
- disconnect the probe and electrode cables, then slide off the burner completely from the slide bars. Once this operation has been carried out, fix the flange 11)(Fig. 11) to the boiler plate, interposing the insulating gasket 9)(Fig. 11) supplied.
Use the 4 screws supplied, with a tightening torque of 35 - 40 Nm, after protecting their thread with anti-seize prod
ucts.
The seal between burner and boiler must be airtight. After the start-up (see Ch. 5.3), check there is no leakage of flue
gases into the external environment.
