    si une demande de chaleur est présente, et
    si la température qui est représentative de la température du brûleur à gaz atteint ou tombe au-dessous ou se situe au-dessous du deuxième seuil,
    alors le brûleur (11) à gaz est démarré pour étalonner le rapport de mélange défini de gaz et d'air du mélange gaz/air.
  5. Procédé selon l'une des revendications 1 à 4, dans lequel
    si la valeur qui est représentative du nombre de démarrages du brûleur à gaz et/ou du temps de fonctionnement atteint ou franchit un seuil de sécurité, et
    si une demande de chaleur est présente, et
    si la température qui est représentative de la température du brûleur à gaz est supérieure au deuxième seuil,
    alors le démarrage du brûleur à gaz est retardé et le brûleur (11) à gaz est démarré lorsque la température qui est représentative de la température du brûleur à gaz atteint ou tombe au-dessous du deuxième seuil.
  6. Procédé selon l'une des revendications 1 à 5, la température qui est représentative de la température du brûleur (11) à gaz étant également surveillée après que le brûleur à gaz et l'étalonnage ont été démarrés, le brûleur (11) à gaz étant arrêté soit si l'étalonnage est fini soit si, pendant l'étalonnage, la température qui est représentative de la température du brûleur à gaz atteint ou dépasse un troisième seuil.
  7. Procédé selon la revendication 6, dans lequel
    si l'étalonnage a été démarré lorsqu'une demande de chaleur est présente, et
    si pendant l'étalonnage la température qui est représentative de la température du brûleur à gaz atteint ou dépasse ledit troisième seuil,
    alors l'appareil (10) à brûleur à gaz est placé dans le premier mode de fonctionnement, ou mode de fonctionnement d'hiver, l'étalonnage est poursuivi et la température qui est représentative de la température du brûleur (11) à gaz est surveillée, le brûleur (11) à gaz étant arrêté soit si l'étalonnage est fini, soit si la température qui est représentative de la température du brûleur à gaz reste supérieure au troisième seuil.
  8. Procédé selon l'une des revendications 4 à 7, dans lequel, si le brûleur à gaz et l'étalonnage ont été démarrés lorsqu'une demande de chaleur est présente et si l'appareil (10) à brûleur à gaz a été placé dans le premier mode de fonctionnement, ou mode de fonctionnement d'hiver, pour l'étalonnage, alors l'appareil (10) à brûleur à gaz est ramené au deuxième mode de fonctionnement, ou mode de fonctionnement d'été, avant la modulation de la charge du brûleur à gaz.
