Supply Air system

System was born by a “PUNKER” and RIELLO project and is composed by: Air Fan   120 mm, H: 62 mm with 33 blades Chassis Fixed and adjustable air dampers Suction pipe Adjustable Knob Suction plate

Supply Air system Suction plate + damper (adjustable only with T1 head) The device’s position defined the fan’s performance Fan and fixed damper Suction pipe + adjustable knob (to achieve the correct air excess)

Two main air settings SUCTION PLATE : The system gives the best performance in a specific position named BP. We consider it like as “zero position” Successives adjustaments will be refer to this setting. (We’ll suggest, on handbook, how many mms are necessary add or subtract to BP) ADJUSTABLE KNOB : It’s necesary setting this device to achieve the correct combustion emission values to conform to European Standard (RAL UZ 9) (We’ll give some indications refer to CEN test boiler with zero mbar of back-pressure at the sea level)

BP index SUCTION PLATE position - X mm We change the fan’s performance We change the combustion emissions as example

Supplementary details Damper’s position inside the fan define the system’s performance Small mechanical tollerance degree between different devices to increase fan’s performance Special gasket all around to avoid any air leakages

Thermal gasket to cut the thermal flow towards flame detector and control box 556 SE control box built with SMD technology UV flame detector QRC 6 A4 by L&S Bridge to choose the “spark restoration” Supplementary details

Without jumper : when flame disapperance, burner follows the standard start up cycle. (pre-purge, spark, ts, flame etc.) With jumper (standard) : when flame disapperance, control box gives the spark counts only the safety time Supplementary details
