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 andfixed damper

Suction pipe + adjustable knob(to achieve the correctair 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)

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
