it is advisable to first set the burner to operate on oil and then
on gas.

"MAN" position.
5.3
Adjustments before first firing (gas operation)
Adjustment of the combustion head has been illustrated on
page 27.
In addition, the following adjustments must also be made:
➤
open manual valves down stream and up stream from the gas
train.
➤
Adjust the minimum gas pressure switch to the start of the
scale (Fig. 26).
➤
Adjust the air pressure switch to the zero position of the scale
(Fig. 27).
➤
Purge the air from the gas line.
Fit a manometer (Fig. 28) to the gas pressure test point on the
sleeve. The manometer readings are used to calculate the
high fire burner firing rate using the table on page 22.
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.
