Servomotor
The air flap is adjusted via an electrical
servomotor (type SQM50/481 A2).
The eight cams of the servomotor are
used to adjust the air flap setting to the
various points of the burner's operation.
When operating with gas, a three-point
regulator is available to give step-free
regulation of the volume of combustion air.
Setting
· Set the cams manually or with the
key provided, in accordance with the
required burner power and the
values indicated in the setting table.
The following relationships must be
observed between cam settings:
· When operating with gas, the
ignition load (cam III) setting can be
above or below the low load
(cam V) setting.
· When operated with oil, the ignition
stage is the same as the first stage.
VI VII VIII
· Cam VII must be adjusted a few
degrees below cam VI.
