Servomotor

The servomotor provides simultaneous adjustment of the air damp-
er, by means of the variable profile cam, and the gas butterfly
valve.
The angle of rotation of the servomotor is equal to the angle on the
graduated sector controlling the gas butterfly valve. The servomo-
tor rotates through 90 degrees in 25 seconds.
Do not alter the factory setting for the cams; simply check that they
are set as indicated below:

Red cam: 90°

Limits rotation toward maximum position.
When the burner is at max output the gas butterfly valve must be
fully open: 90°.

Blue cam: 0°

Limits rotation toward the minimum position. When the burner is
shut down the air damper and the gas butterfly valve must be
closed: 0°.

Orange cam: 15°

Adjusts the ignition position and the MIN output.
