Ideal system connection:
Piping diameters and length requirement:
The diameter ΦA required for the inlet pipe is recommended on the specication table.
The diameter ΦB required for the branch pipe (from to ) should be 2 times as large as ΦA. ΦB
= 2 x ΦA
The diameter ΦC required for the primary air supply (from to ) should be 3 times as large as ΦA.
ΦC = 3 x ΦA
The length for the inlet pipe should be less than 15 feet (4.5m).
