The patent file contains at least one drawing executed in color. Copies of this patent with color drawings will be provided by the Office upon request and the payment of the necessary fee. 
         FIG. 1  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a first image of the transitional graphical user interface; and 
         FIG. 2  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a second image of the transitional graphical user interface; and 
         FIG. 3  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a third image of the transitional graphical user interface; and 
         FIG. 4  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a fourth image of the transitional graphical user interface; and 
         FIG. 5  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a fifth image of the transitional graphical user interface; 
         FIG. 6  is a front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a sixth image of the transitional graphical user interface; 
         FIG. 7  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a first image of the transitional graphical user interface; and 
         FIG. 8  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a second image of the transitional graphical user interface; and 
         FIG. 9  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a third image of the transitional graphical user interface; and 
         FIG. 10  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a fourth image of the transitional graphical user interface; and 
         FIG. 11  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a fifth image of the transitional graphical user interface; and, 
         FIG. 12  is another front view of a display screen or portion thereof with transitional graphical user interface for an ignition sequence for a boiler or water heater showing our new design and illustrating a sixth image of the transitional graphical user interface. 
       The outer perimeter shown in broken line in the FIGURES depicts a display screen or portion thereof with graphical user interface for an ignition sequence for a boiler or water heater and forms no part of the claimed design. The remaining broken lines show portions of the transitional graphical user interface that form no part of the claimed design. 
       The appearance of the image transitions sequentially between the images shown in  FIGS. 1-6, and 7-12 , respectively. The process or period in which an image transitions to another forms no part of the claimed design.
