FLAME PATTERNS

Figure 6 shows a correct flame pattern. The burner flame is mostly blue with a slight yellow coloring on the ends.

Figure 7 shows an incorrect flame pattern. The flame is mostly yellow. The incorrect flame pattern results from low gas pressure or from flashback.

Running heater below specified

input rating may cause flashback. During flashback, the burner flame is mostly yellow. The flame will burn inside the burner tube, causing a roaring noise. If flashback occurs, turn heater off. After burner tube cools, restart the heater.
