Page 14: Air Adjustment
FUNCTION, 2-STAGE DESIGN AIR ADJUSTMENT The damper motor turns the damper between three pre-set positions: fully closed, low load, full load. These positons are controlled in the motor by cams of different colours. The black cam controls the gas valve for full load. If the air volume needs changing: Remove the cover of the damper motor and change the position of the cams by turning them with the tools accompanying the burner. - Page 15 MULTI-BLOC, MB-ZRDLE 405-420 Max. inlet pressure: 360 mbar. 1.
