GENERAL STANDARDS MU
This manual is an integral and essential part of the product and must be given to the installer.
Read the warnings given in this manual as they supply important indications regarding installation, use and main-
tenance safety.
Keep this manual carefully for future reference. The burner must be installed in compliance with the Standards
in force, according to the manufacturer’s instructions and by qualied staff Incorrect installation can cause injury/
damage to persons, animals or objects, for which the manufacturer cannot be held responsible.
This appliance must only be destined for the use for which it was expressly declared.
Any other use must be considered improper and therefore dangerous.
The manufacturer is not liable for any damage caused by improper, incorrect or unreasonable use.
Before carrying out any cleaning or maintenance, disconnect the appliance from the mains power supply by acting
on the system switch or via the relevant shut-off elements.
In the case of breakdown and/or bad functioning of the appliance, deactivate it and do not attempt repairs or direct
interventions.
Only contact qualied professional staff.Any product repairs must only be performed by an after-sales centre au-
thorised by the manufacturer, using original spare parts.
Failure to comply with the above can compromise appliance safety.
In order to guarantee the efciency of the appliance and its correct functioning, it is indispensable to follow the
manufacturer’s indications.
Have qualied professional staff perform periodic maintenance of the appliance.Whenever the appliance is no
longer to be used, the parts that may become a potential source of danger must be made harmless.
Before commissioning the burner, have qualied staff check:
a) that the plate data are those requested by the gas electricity mains supplies;
b) that burner calibration is compatible with boiler power;
c) that the ow of combustion agent air and the evacuation of ue gases take place correctly according to
Standards in force;
d) that aeration and normal maintenance of the burner are guaranteed.
Before performing any intervention that envisions disassembly of the burner or opening of the inspection access
points, disconnect the electric current.
Do not deposit containers of inammable substances in the room where the burner is situated.
The burner room must have openings towards the outside in compliance with local Standards in force. If in doubt
relative to the circulation of air, rst of all we recommend that the CO2value is measured, with the burner functio-
ning at maximum ow rate and the room ventilated, only via the apertures destined to feed air to the burner and
then by measuring the CO2value again, with the door open.The value of CO2measured in both cases must not
change in a signicant manner.
If there are more than one burner and fan in the same room, this test must be performed with all appliances fun-
ctioning simultaneously.
NNever obstruct the air apertures of the burner room, the burner fan intake apertures and any air duct or ventilation
grid and external dissipations, with the purpose of preventing:
- the formation of toxic/explosive gas mixtures in the air of the burner room;
- combustion with insufcient air, from which dangerous, costly and polluting functioning occurs.
The burner must always be protected from rain, snow and freezing.

The burner room must always be kept clean and free from volatile substances, which could be sucked inside the
fan and block the interior pipes of the burner and the combustion head. Dust is extremely dangerous, especially if
this can deposit on the fan blades, where it will reduce ventilation and produce pollution during combustion. The
dust an also accumulate on the rear part of the ame stability disc in the combustion head and cause a poor air/
fuel mixture.
The burner must be fed with the type of fuel for which it has been set-up as indicated on the data plate and in the
technical features supplied in this manual. Moreover, it must be supplied with all control and safety devices reque-
sted by local regulations in force. Pay great care that no external material enters the line during installation.
Make sure that the electric power supply used for the connection is in compliance with the features indicated on the
data plate and in this manual.Make an electric plant with an effective connection to an earth plant, in compliance
with Standards in force. The earth cable must be a couple of cm. longer that the phase and neutral wire.
If in doubt regarding efciency, it must be checked and controlled by qualied staff.Never exchange the neutral
and phase cables.The burner can be connected to the mains electricity with a plug-socket connection only if this is
equipped in a way that the coupling conguration prevents the inversion of phase and neutral.Install an omnipolar
switch with opening between contacts of at least 3mm upstream from the appliance as requested by the existing
legislation.
The entire electric system and in particular all cable sections, must be suitable for the maximum absorbed power
value indicated on the appliance data plate and in this manual.
If the burner power supply cable is faulty, it must only be replaced by qualied staff.Never touch the burner with
wet body parts or without wearing shoes.
Never stretch (force) power supply cables and keep them away from heat sources.The length of the cables used
must allow the burner and any boiler door to be opened.
The electric connections must be made exclusively by qualied staff and the regulations in force on the subject of
electricity must be respected.After all packaging material has been removed, control the contents and ensure that
these have not been damaged in any way during transport.
If in doubt, do not use the burner and contact the supplier.
The packaging materials (wooden cages, cardboard, plastic bags, expanded materials, staples, etc...) represent
a form of pollution and potential risk if left everywhere. Collect them and dispose of them in a suitable manner (in
a suitable place).

Special functions
Network frequency self-learning
The board can automatically optimise the functioning times in relation to the network frequency measured (50 or 60 Hz).
Temporary shutdown
With ignition request in progress or burner functioning, it is possible to temporarily force a stop by continuous pressing of the
key for longer than 5s (yellow fast ashing).
A new start-up cycle is allowed only when the key is released.It is possible to activate the function in question also with the
external release button.
The function in question can only be activated by accessing the INSTALLER MENU.
Pump engagement
If the appliance is in block status, it is possible to force a pump engagement status.
By continuous pressing of the key for a time exceeding 6s and successive release of the same, there is a fast green/yellow/
red ashing phase with duration of 3 s.If the key is pressed and released within this timed period, the motor and pump are
activated for duration of 30s.
The procedure must be repeated in order to deactivate the function before the timing expires.It is possible to activate and
deactivate the function in question also with the external release button.
The function in question can only be activated by accessing the INSTALLER MENU.
Protection in case of low voltage power supply

The power supply voltage must be at least 180Vac in order to allow a starting cycle to be performed.
If the network voltage falls below 156Vac, the appliance stops and signals the anomaly.
The starting cycle can only be carried out again if the power supply voltage exceeds 180Vac.
Protection in case of high power supply voltage
The power supply voltage must be at below 275Vac in order to allow a starting cycle to be performed.If the network voltage
exceeds 280Vac, the appliance stops and signals the anomaly.
The starting cycle can only be carried out again if the power supply voltage falls below 275Vac.
Functioning in manual mode for burner calibration (delegated to authorised staff).
It the appliance is not in the block state, it is possible to force the MANUAL functioning mode by acting on the button on the
board or on the remote release button.
In fact, by pressing the button 3 times (on the board or remote reset) access the green fast ashing display; another press
causes the activation of the MANUAL functioning mode.In this phase, the appliance initiates the start-up cycle or remains
functioning independently from the status of the heat request thermostat and the functioning regulator.
It the appliance is not in the block state, it is possible to force the MANUAL functioning mode by acting on the button on the
board or on the remote release button.
In fact, by pressing the button 3 times (on the board or remote reset) access the green fast ashing display; another press
causes the activation of the MANUAL functioning mode.In this phase, the appliance initiates the start-up cycle independently
from the status of the heat request thermostat and the functioning regulator.
Once the functioning position has been reached, it is possible to pass from one functioning stage to the next by just acting on
the button.
At every press and release of the button, pass to the next intermediate stage until reaching the third stage (three-stage burner).
Press again to return to the previous until reaching the rst stage position.
(If the two-stage burner passes from the rst stage position to the second stage position and vice versa).
(If the modulating burner passes from the minimum modulation position to the maximum modulation position and vice versa).
During the MANUAL functioning phase, the number of yellow ashings indicate the current functioning status (1 ash = rst
stage or minimum modulation, 2 ashes = second stage or maximum modulation, 3 ashes = third stage).
If the signal becomes ashing red during MANUAL functioning, check the position of the servo-motor cam (cam position ano-
maly signal); the burner will however remain in functioning mode.
The procedure must be repeated to deactivate the manual functioning mode.It is also possible to deactivate the manual fun-
ctioning mode by not acting on the button until the relative timeout has expired (see table of times).The function in question
can only be activated by accessing the INSTALLER MENU.
Servo-motor self-learning
The board can automatically acquire the times relative to the damper control servo-motor, it is therefore not necessary to
perform any calibration.
It is however necessary to use servo-motors with 0-90° run times no less than 2s and not exceeding 120s.
Feedback verication and sequence control
If there is no feedback signal relative to reaching a determined position by the air damper, the system performs a block shut-
down and signals the anomaly (block due to servo-motor anomaly).
Also present is a control of the arrival sequence of the feedback signals to the appliance.
If an incorrect arrival sequence of the appliance damper position signals occurs, the appliance will perform a block shutdown
(block due to servo-motor anomaly).
Monitoring of functioning
The board provides the continuous monitoring of the functioning status of the motor and solenoid valves.
MOTORIf there is no monitor signal or incorrect signal presence, at least 3 attempts are made to perform the start-up cycle. If
this anomaly persists, the board will carry out a block shutdown (burner control anomaly).
SOLENOID VALVESIf there is no monitor signal, at least 3 attempts are made to perform the start-up cycle. If this anomaly
persists, the board will carry out a block shutdown (burner control anomaly).If there is an incorrect monitor signal, the board
performs an immediate block shutdown (burner control anomaly).
Block shutdown and rearm
The button allows the reset of the appliance if it is in the block state.The appliance is released when the button is pressed and
then released (button on board or external release button).
The appliance can be released by the button on the board of the external release button.For the appliance to be released, the
button must be pressed for a period of time exceeding 0.2s but less than 4s.
In the case of block shutdown with manual rearm, 5 consecutive rearm operations are possible.
After which rearm is possible again:
- after 1 h ( n° 1 additional rearm is allowed every hour).
- removing the mains power supply.
The rearm operation is only possible if the appliance is supplied with mains voltage.Intermittent serviceThe board performs a
regulation shutdown with self-diagnosis at least every minimum 18h - maximum 24h.

Ignition
On closure of the heat request contact, the fan motor and ignition transformer are inserted and total opening of
the air damper is commanded.
On reaching total opening the pre-ventilation (and pre-ignition) time starts during which the ame amplier test is
performed along with components associated to safety functions. An amplier fault that corresponds to a ame
present condition or the breakdown of a component that ensures a safety function prevents the start of the ignition
sequence.At the end of the pre-ventilation time the air damper is positioned in the rst stage ignition position with
consequent start of the safety time, during which the rst stage solenoid valve is inserted.
With ame signal presence, the ignition transformer is kept inserted until the end of the post-ignition time and
however, no longer than 3s after the end of the safety time.
If there is no ignition during the safety time, the appliance is blocked and the voltage is denitively removed to the
rst stage solenoid valve and the ignition transformer. Post-ventilation is performed with the damper totally open,
at the end of which the air damper is closed completely.
Functioning
The external regulator, both 2-stage and 3-stage burners or modulating burners, act to satisfy the proportion of
heat requested.
The opening of the request contact determines the closure of the solenoid valve, burner switch off and, if envisio-
ned, execution of the post-ventilation phase with total opening of the air damper.When the fan is switched off the
air damper then closes completely.

Display
The control and command panel makes 3 display methods available:
NORMAL:
in this mode, icons appear on the display that are relative to the burner functioning state.
If there are no anomalies present, the display shows the number of ignition cycles performed by the burner and
the total number of functioning hours.
If an anomaly occurs, the display shows the relative code and signals the type of anomaly, (volatile or non-
volatile).Additional information regarding the burner status is also displayed (e.g. valves sealing control proce-
dure) and any execution of special functions for enabled staff.
MENU:
by pressing key i during the normal display mode, access the list of menus:
- INFO (Information)
- HIST (Anomalies log)
- PARAM (Parameters)
- SERV (Installer)
Use the + and - keys to scroll the list.
Press key i again to access one of the menus.
To exit the menu or the list of menus, press R or wait 60 s without pressing any buttons to go back to the normal
display.
MODIFY PARAMETER:
The values of the parameters linked to burner functioning can be modied and memorised.
During the display of the parameter of interest, it is possible to access the value modication by pressing key
i.
In this phase the current parameter value starts to ash and by pressing the + and – keys it is possible to mo-
dify the value.
Press key i to save the modied value.
To exit the parameter modication mode without saving, wait 10s without pressing any buttons or press the R
key.
Normal display mode
By connecting the GB2 board to the mains power supply, the CP45 interface is automatically powered, which for
a few seconds switches on all icons and segments of the display in order to check correct functioning.
When this has been carried out, automatic access is given to the NORMAL DISPLAY mode, during which, in
absence of anomalies, the icons are switched on and off in relation to the functioning of the various burner com-
ponents.
Also with no anomalies present, the total number of ignition cycles performed is displayed along with the total
functioning hours of the burner.
