4.5 COMBUSTION HEAD SETTING

(see figs. 16 and 17)
This is done when fitting the nozzle, with the blast
tube removed. It depends on the output of the
burner and is carried out by rotating the regulating
rod, till the terminal plane of the blast tube is level
with the set-point, as indicated in the schedule.
Example
In the sketch on fig. 16, the combustion head is set
for an output of 1.50 GPH at 14 bar, while the
shutter is level with set-point 2.5, as required by
the above schedule.
Combustion head settings indicated in the sched-
ule are valid for most cases.
The setting of the fan output according to the installation should normally be done only through the air
damper. Should one subsequently want to retouch also the setting of the combustionhead, with the burner
running, operate on the rod (1) with a 6 mm spanner (2).
