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.
Technical label
Tampering, removal or absence of plate
burner or anything that not allow the
secure identification of the burner make
difficult for any installation and
maintenance activity.
Notes for the operator
The system should be inspected by a

Function  General safety functions
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 24
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 ionisation
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. The
ionisation current must be at least 1,5 μA.
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, lasting no more than 3 seconds,
and the gas valve will close.
- If the flame goes out during operation,
the gas supply is interrupted within one
second. A restart takes place. Once the
burner starts, operation is continued.
Otherwise, a safety lock-out occours.
- If there is a lack of air during reventilation
or operation, a safety lock-out occours.
- If there is a lack of gas, the burner does
not begin operation or switches off.
A waiting time of 2 minutes follows. This is
followed by a further start attempt. If there
is still no gas pressure, a further waiting
time of 2 minutes follows. The waiting time
can only be reset by interrupting the
power supply to the burner.
Waiting times: 3 x 2 min, then 1 hour.
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.

The E-BCU GAS fuel gas control and
safety unit controls and monitors the
forced draught burner.
The microprocessor-controlled program
sequence ensures maximum stability of
time periods, regardless of fluctuations in
the power supply or ambient temperature.
The design of the automatic combustion
control unit protects it from the effects of
brownouts. Whenever the supply voltage
drops below its rated minimum level (170
V), the control unit shuts down - even in
the absence of a malfunction signal. The
control unit switches itself back on again
once the voltage has exceeded the 178 V.

These values have been determined in
our test labs and are useful for the first
switch-on as final setting must be done
using a combustion analyzer.
How to read and adjust the values:
- determine the output required
- determine the combustion chamber back-
pressure
- read the minimum gas pressure required
in the diagrams in appendix.
Warning: the pre-calibration values have
been determined on EN676 test combu-
stion chambers in ideal conditions, and are
useful for the first switch-on but must be
checked and corrected with calibration for
the individual system.
Example in figure:
Power required by the generator: 380 kW.
Pressure envisaged in combustion cham-
ber: 3.5 mbar. Combustion head chamber:
2.5 (between 2 and 3). Gas pressure in
head: 13 mbar.

Operating check
Flame monitoring must be checked
for safety as part of initial
commissioning and also after servicing or
if the system has been out of operation for
any significant period of time.
- Start attempt with gas ball valve closed:
the automatic combustion control unit must
switch to gas shortage or malfunction after
the end of the safety period.
Air pressure switch calibration
The air pressure switch is provided for
monitoring the pressure of the
combustion air fan.
Unscrew screws A and B and remove
cover C. After the air and gas setting you
have to calibrate the air switch with the
burner working on the low flame by slowly
turning the relative knob clockwise until the
burner locks out. Read the value and then
decrease it by 15%.
WARNING: the air pressure switch
shall prevent the air pressure to go
below 85% from the adjustment
value in order to prevent the CO in the
fumes to exceed 1% (10000 ppm).
Min gas pressure switch
The gas pressure switch has the function
to check that the gas pressure before the
gas valve does have the minimum
pressure to make the burner running
correctly. Unscrew off and remove cover

WARNING
Descrizione del bruciatore
I bruciatori MAX GAS P sono bruciatori
monostadio completamente automatici La
geometria della testa di combustione
permette di ottenere bassi livelli di NOx e
di incombusti, massimizzando quindi il
rendimento del generatore. Le emissioni
possono essere diverse da quelle
riscontrate nel laboratorio di prova in
quanto dipendono molto dal generatore sul
quale il bruciatore è installato.
L’installatore deve rispettare le normative
vigenti. Per esempio sono da evitare locali
con atmosfere pericolose o non ventilate.
Targa dati
La manomissione, l’asportazione, la
mancanza della targhetta del bruciatore o
quant’altro, non permettono la sicura
identificazione del bruciatore e rendono
difficoltosa qualsiasi operazione di
installazione e manutenzione.
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
dell'impianto.

Funzione  Funzioni generali di sicurezza
Descrizione del funzionamento
Alla prima messa sotto tensione, dopo
un'interruzione di corrente e una fase di
messa in sicurezza, dopo un'interruzione
di gas o dopo un arresto di 24 ore,
comincia un tempo di preventilazione di
24 sec.
Durante il tempo di preventilazione:
- la pressione dell'aria viene monitorata.
- controllo della presenza di eventuali
segnali di fiamma anomali.
Al termine del tempo di preventilazione
- l'accensione e inserita.
- l'elettrovalvola principale e di sicurezza e
aperta.
- il bruciatore si avvia.
Sorveglianza
La fiamma viene monitorata da una sonda
di ionizzazione. La sonda e montata in
modo isolato sulla testa del gas ed e
diretta attraverso il disco fiamma nella
zona della fiamma. La sonda non deve
avere alcun contatto elettrico con
componenti messi a terra. Se compare un
cortocircuito tra la sonda e la massa del
bruciatore, il bruciatore entra in stato di
anomalia. Durante il funzionamento, nella
fiamma del gas si crea una zona
ionizzata, attraverso la quale circola una
corrente raddrizzata dalla sonda verso il
boccaglio. La corrente di ionizzazione
deve essere superiore a 1,5 μA.
Funzioni di sicurezza
- Se all'avvio del bruciatore (rilascio del
gas) non si forma la fiamma, il bruciatore
viene arrestato al termine di un intervallo
di sicurezza di max. 3 secondi, la valvola
del gas si
chiude.
- In caso di anomalia della fiamma
durante il funzionamento, l'alimentazione
del gas si interrompe nella frazione di un
secondo. Viene avviata una nuova messa
in funzione. Se il bruciatore si avvia, il
ciclo di funzionamento prosegue. In caso
contrario si instaura una fase di messa in
sicurezza.
- In caso di mancanza d'aria durante la
preventilazione o il funzionamento, si
instaura una fase di messa in sicurezza.
- In caso di mancanza di gas, il bruciatore
non si mette in funzione e/o si arresta.
Segue un tempo di attesa di 2 minuti al
termine del quale avviene un nuovo
tentativo di avvio. Se la mancanza di
pressione del gas perdura, si avvia un
nuovo tempo di attesa di 2 minuti.In
questo caso, il tempo di attesa puo essere
interrotto esclusivamente dallo
spegnimento del bruciatore. Tempo di
attesa: 3 x 2 min., poi 1 ora.
Arresto di regolazione
- Il termostato di regolazione interrompe la
richiesta di riscaldamento.
- Le valvole gas si chiudono.
- La fiamma si spegne.
- Il motore del ventilatore si ferma
- Il bruciatore e pronto per il
sucessivo funzionamento.

Il programmatore di comando e sicurezza
gas E-BCU GAS comanda e sorveglia il
bruciatore ad aria soffiata. Grazie al pro-
gramma gestito dal microprocessore, si
ottengono tempi estremamente stabili, in-
dipendentemente dalle oscillazioni della
tensione di rete o della temperatura am-
biente. Il programmatore di comando e si-
curezza e progettato per essere sicuro in
caso di sottotensione. Se la tensione di
rete scende al di sotto del valore minimo
richiesto (170 V), il programmatore di co-
mando si disattiva senza alcun segnale
d'errore. Non appena la tensione supera i
178 V, il programmatore si riavvia automa-
ticamente.
Blocco e sblocco
Il programmatore di comando puo essere
bloccato (portato in condizione di anoma-
lia) e sbloccato (rimozione anomalia) me-
diante il pulsante R a condizione che nel
programmatore di comando sia presente
tensione di rete.
Prima del montaggio o dello
smontaggio del programmatore
di comando l'apparecchio
dev'essere a tensione nulla.
Il programmatore di comando
non dev'essere aperto nè
riparato.
