AIR REGULATION
With PM/M-E type burners, the air flap is activated by an electric servo control. The air flap positions are
determined by means of the cams, with their alignment indicated on the reference disc.
The cams can be moved by using the equipped wrench as they are self-locking.
By pressing button B, the air flap drive system is disengaged, and the air flap is free to be moved manually (if
necessary).
