10.15 Adjustments before First Firing (Gas Operation)
Adjustment of the combustion head has been illustrated in Figures 10-4 and 10-5.
In addition, the following adjustments must also be made:
•
Open manual valves up-stream from the gas train.
•
Purge the air from the gas line.
•
Adjust the minimum gas pressure switch shown in Figure 1016 to the start of the scale.
•
Adjust the maximum gas pressure switch shown in Figure 10-15 to the upper limit of the
scale.
•
Adjust the air pressure switch shown in Figure 10-14 to the zero position of the scale.
•
Fit a U-type manometer shown in Figure 10-12 to the gas pressure test point on the
sleeve. The manometer readings are used to calculate MAX burner power using Table J,
in section 10.8, above.

CAUTION!
Before starting up the burner it is good practice to adjust the gas train so that ignition takes
place in conditions of maximum safety, i.e., with gas delivery
at the minimum.
