motor rotation and keep pressing for some seconds until the oil circuit is charged;

bleed the air from the

Before starting the burner up, drive the high flame actuator microswitch matching the low flame one (in order to let the burner ope-
rates at the lowest output) to achieve safely the high flame stage .
5
record the high flame value set during the gas operation adjustments (see previous paragraphs);
6
start the burner up by means of the thermostat series and wait until the pre-purge time comes to an end and that the bruner starts
up;
7
drive the burner to high flame stage, by means fo the thermostat
TAB
.
8
Then move progressively the microswitch to higher values until it reaches the high flame position; always check the combustion
values and eventually adjusting the oil pressure (see next step).
9
the nozzle supply pressure is already factory-set and must not be changed. Only if necessary, adjust the supply pressure as fol-
lows (see related paragraph);insert a pressure gauge into the port shown on Fig. 23 and act on on the pump adjusting screw
VR
(see Fig. 22 and page 20) as to get the nozzle pressure at 25bar (according to the nozzle model provided- see page 29).
