Burner description
MAX GAS P are single-stage, fully
automatic, monoblock type burners.
Burner head is designed to get the lowest
emissions in terms of NOx and unburnt
particles in order to maximize the heat
generator efficiency. Emissions can be
different respect to the ones recorded in
the lab because they depends a lot on the
generator on which the burner is fit.
The installer must comply with compulsory
rules. Avoid for instance dangerous
atmosphere or not ventilated rooms.
Packaging and handling
Move the burner still in its packaging using
a trolley or forklift, taking care not to drop it
and elevating it no more than 20cm from
ground level. After having removed the
packaging, check that the contents are in
good condition and correspond with what
was ordered. If in doubt, contact the
manufacturer.
The burner must be installed by a
qualified individual.
If the weight and dimensions do not allow
for manual lifting, ask another operator for
help or use a forklift, harness the burner
using belts if no eyebolts are available.
Use the accessories provided
(flange, gasket, pins and nuts) to
install the burner onto the boiler,
taking care not to damage the
isolating gasket.
We can accept no warranty liability
whatsoever for loss, damage or injury
caused by any of the following:
- Inappropriate use.
- Incorrect assembly or repair by the
customer or any third party, including the
fitting of non-original parts.
Provision of the system and the
operating instructions
The firing system manufacturer must
supply the operator of the system with
operating and maintenance instructions on
or before final delivery. These instructions
should be displayed in a prominent
location at the point of installation of the
heat generator, and should include the
address and telephone number of the
nearest customer service centre.
Notes for the operator
The system should be inspected by a
specialist at least once a year. It is
advisable to take out a maintenance
contract to guarantee regular servicing.

Description of functions
When the system is switched on for the
first time, after a power failure or safety
shutdown, after a lack of gas or after the
system has been out of operation for 24
hours, the pre-ventilation period of 30
seconds begins.
During prepurge period:
- blower pressure is monitored
- the combustion chamber is monitored for
flame signals.
At the end of the prepurge period:
- ignition is switched on.
- main and safety valve are opened.
- burner starts.
Monitoring
The flame is monitored by an ionization
probe. The probe is insulated and fitted to
the gas head and is routed through the
flame disc into the flame zone. The probe
must not have any electrical contact with
earthed parts.The burner switches to lock-
out if a short circuit occurs between the
probe and the burner earth. During burner
operation, an ionised zone is produced in
the gas flame through which a rectified
current flows from the probe to the burner
head.
Safety functions
- If no flame is produced when the burner
is started (gas release), the burner will be
switched off at the end of the safety period,
and the gas valve will close.
- If the flame goes out during operation,
the gas supply is interrupted and the
control unit goes to block.
- If there is a lack of air during reventilation
or operation, the control unit goes to block.
- If there is a lack of gas, the burner does
not begin operation or switches off.
In the event of controller shutdown
- Controller thermostat interrupts heat
request.
- Gas solenoid valves close.
- Flame goes out.
- Burner motor switches off.
- Burner is ready for operation.

contenuto sia integro e corrisponda al
prodotto ordinato. In caso di dubbi,
contattare il produttore.
L’installazione del bruciatore
deve essere effettuata
da personale abilitato.
Se le dimensioni e il peso non consentono
un sollevamento manuale, farsi aiutare da
un altro operatore, od utilizzare un
sollevatore imbracando il bruciatore con
delle fasce se non disponibili i golfari.
Usare gli accessori in dotazione
(flangia ,guarnizione, perni e dadi)
per installare il bruciatore alla
caldaia facendo attenzione a non
danneggiare la guarnizione isolante.
Si esclude qualsivoglia responsabilità
per eventuali danni derivanti dalle
seguenti cause:
- utilizzo non conforme.
- montaggio difettoso e/o riparazione a
cura dell'acquirente o terzi, ivi inclusa
l'applicazione di elementi di origine
estranea.
Consegna e istruzioni per l'uso
Il costruttore dell'impianto di combustione
è tenuto a consegnare al gestore
dell'impianto, al più tardi all'atto della
consegna dello stesso, le istruzioni per
l'uso e la manutenzione. Queste istruzioni
devono essere appese nel locale di
installazione del generatore termico in
modo ben visibile. Devono essere indicati
l'indirizzo ed il numero telefonico del punto
di assistenza più vicino.
Avvertenza per il gestore
L'impianto dev'essere controllato almeno
una volta l'anno da un tecnico specia-
lizzato. Al fine di garantire un'esecuzione
regolare, si suggerisce di stipulare un
contratto per la manutenzione
