• Diaphragm installation
For proper boiler operation a diaphragm must be installed on
the outlet of the sealed chamber and before the intake and ex-
haust pipe (Fig. 10).
e appropriate diaphragm is chosen based on type of pipe and
its maximum extension: this calculation can be made using the
tables below:
N.B.: the diaphragms are supplied together with the boiler.
Diaphragm
Duct length in metres
Ø 60/100 horizontal
Ø 38 From 0 to 1
Ø 42.5 Exceeding 1 up to 3
Diaphragm
Duct length in metres
Ø 60/100 vertical
Ø 38 From 0 to 3
Ø 42.5 Exceeding 3 up to 4.5
Diaphragm
Duct length in metres
Ø 80/125 horizontal
Ø 38 From 0 to 3
Ø 42.5 Exceeding 3 up to 7. 5
Diaphragm
Duct length in metres
Ø 80/125 vertical
Ø 38 From 0 to 8
Ø 42.5 Exceeding 8 up to 12
Diaphragm
(*) Extension in metres
Ø 80 horizontal pipe with two
bends
Exhaust Intake
Ø 40 Ø 55 From 0 to 8
Exhaust Diaphragm
(*) Extension in metres
Ø 80 horizontal pipe with two
bends
Ø 40 Exceeding 8 up to 35
Diaphragm
(*) Extension in metres vertical
pipe Ø 80 without bends
Exhaust Intake
Key:
1 - Discharge diaphragm:
Ø 38; Ø 40; Ø 42,5
2 - Intake diaphragm: Ø 55
Diaphragm
(*) Extension in metres vertical
pipe Ø 80 without bends
Ø 40 Ø 55 From 0 to 12
Exhaust Diaphragm
(*) Extension in metres vertical
pipe Ø 80 without bends
Exhaust Intake
Ø 40 From 12 to 40
Diaphragm
(**) Extension in metres
Ø 80 horizontal pipe with two
bends
Exhaust Intake
Ø 40 Ø 55 From 0 to 8
Intake Diaphragm
(**) Extension in metres
Ø 80 horizontal pipe with two
bends
Ø 55 Exceeding 8 up to 27
Diaphragm
(**) Extension in metres
Ø 80 vertical pipe without bends
Exhaust Intake
Ø 40 Ø 55 From 0 to 12
Intake Diaphragm
(**) Extension in metres
vertical pipe Ø 80 without bends
Ø 55 Exceeding 12 up to 33
(*) ese maximum extension values are considered intake with 1
metre exhaust pipe.
(**) ese maximum extension values are considered exhaust with
1 metre intake pipe.
