WARTUNG

Verbrennung

Die Abgase der Verbrennung analysieren.
Bemerkenswerte Abweichungen im Vergleich
zur vorherigen Überprüfung zeigen die Stelle
an, wo die Wartung aufmerksamer ausgeführt
werden soll.

Gasundichtigkeiten

Die Zähler-Brenner-Leitung auf Gasundichtig-
keiten kontrollieren.

Gasfilter

Verschmutzten Gasfilter austauschen.

Flammkopf

Den Brenner öffnen und überprüfen, ob alle
Flammkopfteile unversehrt, nicht durch hohe
Temperatur verformt, ohne Schmutzteile aus
der Umgebung und richtig positioniert sind.

Spannung an der QRI-Zelle

Mindestwert für korrekten Betrieb: 3,5 Vdc
(Flammbildschirm ca.  50%).
Sollte der Wert darunter liegen, so kann dies fol-
gende Ursachen haben:

• Zelle in unkorrekter Position;
• zu niedrige Spannung (unter 187 V);
• schlechte Einstellung des Brenners.

Zur Messung ein Voltmeter mit Skala 10 Vdc
verwenden, das gemäß Schema angeschlossen
wird, siehe Abb. (A).

Brenner

Es ist zu überprüfen, ob ungewöhnlicher Ver-
schleiß oder die Lockerung der Schrauben vor-
liegen.
Den Brenner von außen reinigen.

Verbrennung

Sollten die am Anfang des Eingriffs angetroffe-
nen Verbrennungswerte nicht mit den gültigen
Vorschriften übereinstimmen oder einer guten
Verbrennung nicht entsprechen, so wenden Sie
sich zur Durchführung der notwendigen Einstel-
lungen bitte an den Technischen Kundendienst.

Anmerkung

Es wird empfohlen, den Brenner je nach benutz-
tem Gastyp gemäß den Angaben in der Tabelle
(C) einzustellen.

ÖFFNUNG DES BRENNERS (B):

- Spannung unterbrechen.
- Die Zugstange 1) des Hebels zur Kopfbewe-

gung durch Lockern der Mutter  2) entfernen.

- Den Steckanschluss 3) des Gasstellantriebs

abtrennen.

- Den Steckanschluss 4) des Gasdruckwäch-

ters abtrennen.

- Die Schrauben 5) abnehmen.
Nun kann der Brenner am Scharnier geöffnet
werden.

MAINTENANCE

Combustion

The optimum calibration of the burner requires
an analysis of the flue gases. Significant differ-
ences with respect to the previous measure-
ments indicate the points where more care
should be exercised during maintenance.

Gas leaks

Make sure that there are no gas leaks on the
pipework between the gas meter and the
burner.

Gas filter

Change the gas filter when it is dirty.

Combustion head

Open the burner and make sure that all compo-
nents of the combustion head are in good condi-
tion, not deformed by the high temperatures,
free of impurities from the surroundings and cor-
rectly positioned.

Power to photocell QRI

Min value for a good work: 3,5 Vdc (display
flame approx. 50%).
If the value is lower, it can depend on:

• photocell positioned incorrectly;
• low current (lower than 187 V);
• bad regulation of the burner.

To measure power, use a voltmeter with a 10
Vdc scale, connected as illustrated on the dia-
gram. See fig. (A).

Burner

Check for excess wear or loose screws.
Clean the outside of the burner.

Combustion

In case the combustion values found at the
beginning of the intervention do not respect the
standards in force or, in any case, do not corre-
spond to a proper combustion, contact  the
Technical Assistant and have him carry out the
necessary adjustments.

Note

We recommend calibrating the burner - depend-
ing on the type of gas utilised - according to the
indications given in table (C).

TO OPEN THE BURNER (B):

- Switch off the electrical power.
- Remove the tie rod 1) of the head movement

lever, loosening nut 2).

- Disconnect the gas servomotor test point 3).
- Disconnect the gas pressure switch test point

4).

- Remove screws 5).
At this point it is possible to open the burner at
the hinge.

ENTRETIEN

Combustion

Pour obtenir un réglage optimal du brûleur, il
faut effectuer l'analyse des gaz d'échappement
de la combustion à la sortie de la chaudière. Les
différences significatives par rapport au contrôle
précédent indiqueront les points où l'opération
d'entretien devra être plus approfondie.

Fuites de gaz

Contrôler l'absence de fuites de gaz sur le con-
duit compteur-brûleur.

Filtre du gaz

Remplacer le filtre du gaz lorsqu'il est encrassé.

Tête de combustion

Ouvrir le brûleur et contrôler si toutes les parties
de la tête de combustion sont intactes, ne sont
pas déformées par les températures élevées,
sont exemptes d'impuretés provenant du milieu
ambiant et positionnées correctement.

Courant a la cellule QRI

Valeur minimale pour un bon fonctionnement:
3,5 Vdc (écran flamme approx. 50%).
Si la valeur est inférieure, la cause peut être:

• cellule mal placée;
• tension inférieure à 187 V);
• mauvais réglage du brûleur.

Pour mesurer, se servir d»un voltmètre avec
échelle 10 Vdc branché selon le schéma. Voir
fig. (A).

Brûleur

Vérifier qu'il n'y ait pas d'usure anormale ou de
vis desserrées.
Nettoyer extérieurement le brûleur.

Combustion

Si les valeurs de la combustion relevées au
début de l»intervention ne satisfont pas aux nor-
mes en vigueur ou ne permettent pas une
bonne combustion, contacter le Service après-
vente pour qu»il effectue les réglages qui s»impo-
sent.

Note

Il est conseillé de régler le brûleur selon le type
de gaz utilisé, voir les indications fournies dans
le tableau (C).

POUR OUVRIR LE BRULEUR (B):

- Couper la tension.
- Enlever le tirant 1) du levier du mouvement de

la tête, en desserrant l»écrou 2).

- Débrancher la prise 3) du servomoteur gaz.
- Débrancher la prise 4) du pressostat gaz.
- Retirer les vis 5).
On peut alors ouvrir le brûleur sur la charnière.
