The gas metered in 3 minutes to obtain rated input for
each boiler model, using 1000 Btu/cu. ft. gas, is tabu-
lated in gas rate table.
B. Main Burners
1. Fire the boiler continuously for at least 15 minutes, to
reach burner operating temperature.
2. Observe the flames, all burners. The base of all flame
jets should be blue. The tips should be blue shading
to orange. NOTE: Dust, disturbed by any movement,
will cause bright orange flames. Wait for dust to settle.
3. For one burner, close the air shutter until some of its
flame jet tips turn yellow-white, indicating insufficient
primary air. Then open shutter until whitish tips disap-
pear completely. Set all burner shutters to the same
opening. Observe to make sure that no yellow-white
tips appear over any portion of the flame. Small yel-
low tips at the pilot are per mitted (see Figure 18).
NOTE: This adjustment method gives MINIMUM pri-
mary air setting for safe combustion. DO NOT attempt
to make this adjustment unless burners are at operat-
ing temperature. Adjustment should be made with
burner access panel in final operating position. Use of
a mirror may be helpful to observe flames. Note that
burner ports are on top of main burner tube.
