The GAS P/M series covers a firing range from 80 to 4885 kW.
Operation is featured by progressive two stage operation or full modulation, with an
advanced modulating control system and probes.
The burners of GAS P/M series are well suited for applications requiring versatility of
control (process, steam, refrigerating absorption) where a variable output is needed.
Due to their metal sheet structures, they are specifically suitable for process applications
where plastic materials could be easily damaged or deformed.
Simplified maintenance is achieved by sliding bars which permit the access to the
combustion head without need of removing the burner from the boiler.

FUEL SUPPLY
GAS TRAIN
The burners are fitted with a butterfly valve to regulate the fuel,
controlled by a variable profile cam servomotor.
Fuel can be supplied either
from the right or left hand sides, on the basis of the application
requirments. A maximum gas pressure switch stops the burner
in case of an excess of pressure in fuel line.
The gas train can be selected to best fit system requirements
depending on the fuel output and pressure in the supply line.
The gas train can be “Multibloc“ type (containing the main
components in a single unit) or “Composed” type (assembly
of the single components).
Example of the variable profile cam
on GAS 3-4-5-6-7 P/M burners.

The overall dimensions of the gas train depends on how they are constructed. The following table shows
the maximum dimensions of the gas trains that can be fitted to GAS P/M burners, intake and outlet
diameters and seal control if fitted.
Please note that the seal control can be installed as an accessory, if not already installed on the gas train.
The maximum gas pressure of gas train “Multibloc” type is 360 mbar, and the one of gas train “Composed”
type is 500 mbar.

PRESSURE DROP DIAGRAM
The diagrams indicate the minimum pressure drop of the burners with the various gas trains that
can be matched with them; the value thus calculated represents the minimum required input
pressure to the gas train. All values refer to EN 676 standard:
G20 = 9,45 kWh/Nm3 at 15 °C - G25 = 8,13 kWh/Nm3 at 15 °C - G31 = 24,44 kWh/Nm3 at 15 °C

note
Please contact the Riello Burner Technical Office for different pressure levels from those above
indicated and refer to the technical manual for the correct choice of the spring.
MBC 1200 gas train: the minimum operating pressure (*) is higher or equal to 10 mbar. The gas train has to
be installed next to the burner (if needed, only with the adapters listed in the catalogue) and it has to operate
in its own working field.
MBC 1900-3100-5000 gas train: the minimum operating pressure (*) is higher or equal to 15 mbar. The gas
train has to be installed next to the burner (if needed, with the adapters listed in the catalogue) and it has
to operate in its own working field.
(*) It is the upstream gas train pressure in full load operation conditions.

SELECTING THE FUEL SUPPLY LINES
The following diagram enables pressure drop in a pre-existing gas line to be calculated and to select the
correct gas train.
The diagram can also be used to select a new gas line when fuel output and pipe length are known. The
pipe diameter is selected on the basis of the desired pressure drop. The diagram uses methane gas as
reference; if another gas is used, conversion coefficient and a simple formula (on the diagram) transform
the gas output to a methane equivalent (refer to figure A). Please note that the gas train dimensions must
take into account the back pressure of the combustion chamber during operations.
Control of the pressure drop in an existing gas line or selecting a new gas supply line.
The methane output equivalent is determined by the formula fig. A on the diagram and the conversion
coefficient.
Once the equivalent output has been determined on the delivery scale ( V ), shown at the top of the
diagram, move vertically downwards until you cross the line that represents the pipe diameter; at this
point, move horizontally to the left until you meet the line that represents the pipe length.
Once this point is established you can verify, by moving vertically downwards, the pipe pressure drop
of on the botton scale below (mbar).
By subtracting this value from the pressure measured on the gas meter, the correct pressure value will
be found for the choice of gas train.
- gas used
- gas output
- pressure at the gas meter
- gas line length
- conversion coefficient
Example:
- equivalent methane output V =
G25
9.51 mc/h
20 mbar
15 m
0.62 (see figure A)
9.51
0.62
= 15.34 mc/h
- once the value of 15.34 has been identified on the output scale ( V ), moving vertically downwards you
cross the line that represents 1" 1/4 (the chosen diameter for the piping);
- from this point, move horizontally to the left until you meet the line that represents the length of 15 m
of the piping;
- move vertically downwards to determine a value of 1.4 mbar in the pressure drop botton scale;
- subtract the determined pressure drop from the meter pressure, the correct pressure level will be found
for the choice of gas train;
- correct pressure = ( 20-1.4 ) = 18.6 mbar

VENTILATION
The ventilation circuit comes with a forward blades centrifugal
fan, which gaurantees high pressure levels at the required air
deliveries and permits installation flexibility.
In spite of the remarkable output power and
of the very high pressure performances, GAS P/M models
are extremely compact.
A minimum air pressure switch stops the burner when there
is an insufficient quantity of air at the combustion head.
A variable profile cam connects fuel and air setting, ensuring
fuel efficiency at all firing rates.
Example of servomotor and air damper
of GAS 3 P/M
COMBUSTION HEAD
Two different combustion head lengths can be selected for the
various models of GAS P/M series of burners.
The choice depends on the thickness of the
front panel and type of boiler. Correct head
penetration into the combustion chamber depends on the
type of heat generator.
These burners are equipped with a variable geometry
combustion head. This enables optimum combustion
performance throughout the working field, ensuring peak
combustion efficiency thus saving on fuel consumption.
The following diagram shows the flame dimensions in
relation to the burner output. The lengths and diameter
shown in the diagram below should be employed for
for a preliminary check: if combustion chamber dimensions
are different from the values in the diagram, further tests
Example of GAS 8 P/M combustion head
need to be done.

ADJUSTMENT
BURNER OPERATION MODE
The GAS P/M series of burners
can be “two stage progressive”
or “modulating” operation.
During “two stage progressive”
operation, the burner gradually
adapts the output to the
requested level, by varying
between two pre-set levels (see
picture A).

INSTALLATION DESCRIPTION
Installation, start up and maintenance must be carried out by
qualified and skilled personnel.
All operations must be performed in accordance with the technical handbook supplied with
the burner.
BURNER SETTING
All the burners have slide bars, for easier installation and maintenance.
After drilling the boilerplate, using the supplied gasket as a template, dismantle the blast tube
from the burner and fix it to the boiler.
Adjust the combustion head.
Fit the gas train, choosing this on the basis of the maximum output of the boiler and considering
the enclosed diagrams.
Refit the burner casing to the slide bars.
Close the burner, sliding it up to the flange.
ELECTRICAL CONNECTIONS AND START UP
Make the electrical connections to the boiler following the wiring diagrams included in the
instruction handbook.
Turn the motor to check rotation direction (if it is a three-phase motor).
Perform a first ignition calibration on the gas train.
On start up, check:
- Gas pressure at the combustion head (to max. and min. output)
- Combustion quality, in terms of unburned substances and excess air.
