TECHNICAL AND FUNCTIONAL CHARACTERISTICS
• Two-stage progressive output operation.
• Ability to operate with output modulation by means of automatic RWF40 regulator
mounted on the control panel (to be ordered separately with the modulation kit).
• Ability to obtain optimal combustion values by regulating combustion air and
combustion head.
• Maintenance facilitated by the fact that the mixing unit and the atomisation unit
can be removed without having to remove the burner from the boiler.
• Minimum and maximum air flow regulation for first and second stage by means of
electric servomotor with pause closure of shutter to prevent any heat dispersion
to flue.
• On demand it is possible to integrate the burner with a supplementary fuel oil
preheater operating by vapour which allows, at a rate of flow, to heat the fuel
with vapour from the boiler, hence obtaining electrical energy savings.
• Equipped with 1 insulating gasket to be fixed to the boiler, 2 flexible pipes, self-
cleaning filter with resistor; nozzle not included and to be ordered seperately
according to capability required.
• Optional: vapour preheater
CONSTRUCTION CHARACTERISTICS
The burner consists of the following parts:
• Combustible air intake with device for air flow rate regulation.
• Connection flange on the generator fixed with pin to facilitate the disassembly
of the atomisation unit and the flame disk.
• Air pressure switch to ensure the presence of combustion air.
• Electric servomotor with mechanical cam to simultaneouly regulate the combus
-
tible air and fuel.
• Heating resistor for the pump, the regulating vlave and the atomising unit.
• Atomising unit with magnet for control of the delivery/return nozzle pin.
• Set of 2 mass produced electric preheaters of combustibles which are constructed
with gas valves, self-cleaning filters, thermometer, electronic temperature regula -
tor and safety thermostats.
• Gas train with burner ignition complete with security valve and electromagnetic
functioning, minimum pressure switch, pressure regulator and gas filter.
• Automatic command equipment and burner control according to European
regulation EN230.
• Flame detection by UV photocell.
• Electrical system with protection rating IP40.
These burners are available in a range of versions to suit the em-
ployed fuel type. More specifically, these are:
- GAS (Methane) version GI 1000 DSPGN
- LIGHT OIL version GI 1000 DSPG
- HEAVY OIL (rated viscosity max. 50° E at 50° C) version GI
1000 DSPN-D
- GAS (Methane) / HEAVY OIL (rated viscosity max. 5° E at 50°
C) version GI-Mist 1000 DSPNM
- GAS (Methane) / LIGHT OIL version GI-Mist 1000 DSPGM
Note that the GI-Mist 1000 DSPGM and GI-Mist 1000 DSPNM
burners have been designed for operation with methane gas or
with liquid fuel.
- The “GI 1000” burner is a modulating burner with a modulation
range of 1 - 4. Adjustment to current heat requirements is pro -
vided by means of a servomotor that regulates the combined
quantity of combustion air and fuel according to the signals from
the in-boiler probe.
- The burner is fitted with a device that automatically varies the
cross-section of the air passage in the combustion head, doing so
proportionately to variations in load. This device gives optimum
combustion under all load conditions as a result of optimisation
of the air/fuel mix; there thus results reduced excess of air with
better quality combustion.
FIXING THE BURNER TO THE BOILER
The burner must be fitted to the iron boiler plate where the supplied
studs have been fitted in place beforehand in observance, of course,
of the drilling template.
It is advisable to electrically weld the studs from the internal part of
the plate so that they are not, in the event of burner disassembly,
extracted together with the unit lock nuts. If there is no thermal
insulation on the plate then an insulating layer at least 10 mm thick
must be introduced between the plate itself and the boiler.
Make sure that the combustion head penetrates into the combustion
chamber to the extent requested by the boiler makers.
ELECTRICAL CONNECTIONS
It is advisable to effect all electrical connections with flexible
electrical wire.
Electrical lines must be kept away from hot parts.
Make sure that the power line to which you intend to connect the unit
is of voltage and frequency suitable for the burner. Make sure that
the main power line, the relative fuse-equipped switch (indispen -
sable)and any limiter are able to withstand the maximum current
absorbed by the burner.
For details see the specific wiring diagrams for each individual
burner.
