Riello RS100 TC Burner For Heating industry
Description
The RS burners series covers a firing range from 44 to 2290 kW, and it has been designed for use in low or medium
temperature hot water boilers, hot air or steam boilers, diathermic oil boilers.
Operation is "two stage progressive"; the burners are fitted with a microprocessor-based burner safety control box
which supplies indication of operation and diagnosis of
fault cause.
The elevated performance of the fans and combustion head, guarantee flexibility of use and excellent working at
all firing rates.
The exclusive design ensures reduced dimensions, simple use and maintenance. Optimisation of sound emissions is
guaranteed by the special design of the air suction circuit and by incorporated sound proofing material. A wide range
of accessories guarantees elevated working flexibility.

Specification:
70 - 100 - 130 - 150 - 190 models
Monoblock forced draught gas burner with two stage operation, fully automatic, made up of:
- Air suction circuit lined with sound-proofing material
- Fan with reverse curve blades (RS 50 - 70 - 100 - 130 models) or straight blades (RS 64 MZ - 150-190 models)
- Air damper for air flow setting and butterfly valve for regulating fuel output on 1st and 2nd stage controlled by
a servomotor with variable cam
- Starting motor at 2800 rpm, three-phase 400V with neutral, 50Hz
- Combustion head, that can be set on the basis of required output, fitted with:
- stainless steel end cone, resistant to corrosion and high temperatures
- ignition electrodes
- ionisation probe
- gas distributor
- flame stability disk
- Minimum air pressure switch stops the burner in case of insufficient air quantity at the combustion head
- Microprocessor-based burner safety control box, with diagnostic functions
- Plug and socket for electrical connections (RS 50-64 models)
- Burner on/off selection switch
- 1st - 2nd stage manual switch
- Flame inspection window
- Slide bars for easier installation and maintenance
- Protection filter against radio interference
- IP 44 electric protection level.
Standard equipment:
- 1 gas train flange
- 1 flange gasket
- 4 screws for fixing the flange
- 1 thermal screen
- 4 screws for fixing the burner flange to the boiler
- Wiring loom fittings for the electrical connection (RS 50-64)
- 2 slide bar extensions (for extended head models and RS 150-190 model)
- Instruction handbook for installation, use and maintenance
- Spare parts catalogue.
Burner components:
1 Combustion head
2 Ignition electrode
3 Screw for combustion head adjustment
4 Maximum gas pressure switch
5 Servomotor controlling the gas butter fly valve and the air damper valve (by means of an adjustable profile cam mechanism). When the burner is not operating the air gate valve is fully closed in order to reduce heat dispersion from the boiler
due to the flue draught which draws air from the fan suction inlet.
6 Plug-socket on ionisation probe cable
7 Extensions for slide bars 15)
8 Motor contact maker and thermal relay with reset button
9 Power switch for: automatic - manual - off
Button for: power increase - power reduction
10 Terminal board for electrical wiring
11 Cable grommets for electrical wiring (to be carried out by the installer)
12 Control box with lockout pilot light and lockout reset button
13 Flame inspection window
14 Air pressure switch (differential operating type)
15 Slide bars for opening the burner and inspecting the combustion head
16 Gas pressure test point and head fixing screw
17 Air pressure socket
18 Flame sensor probe
19 Air damper
20 Fan air inlet
21 Screws to secure fan to pipe coupling
22 Gas input pipe
23 Gas butterfly valve
24 Boiler fixing flange
25 Flame stability disc
26 Bracket for application of output power regulator RWF40
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.
