8.When burner remains lit, set heater at the desired heat level by slightly depressing the control knob and turning it counterclock- wise to the MED or HIGH settings (see Figure 4, page 4).
9.If burner goes out, turn off gas. Slightly depress and turn con- trol knob fully clockwise to OFF. Check fuel supply. If ad- equate fuel is available, restart heater beginning at step #1, page 4.
FLAME PATTERNS
Figure 5 shows a correct flame pattern. The burner flame is mostly blue with a slight yellow coloring on the ends.
Figure 6 shows an incorrect flame pattern. The flame is mostly yellow. The incorrect flame pattern results from low gas pressure or from flashback.
CAUTION: 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.
