Cutting the field supplied gas pipes

Use the following tables for standard installation (refer to

If the dimensions exceed these of the standard installation, extend
the L dimension of the suction gas pipes 1~4 and HP/LP gas pipes
1~5 accordingly.

For suction gas pipes only
For L dimension of suction gas pipes 1~4 dimension B of the
field supplied angled joint as in table 14 on page 6 has been
taken into account. If dimension B of the angled joint you use is
different from that dimension B, adjust the L dimension of
suction gas pipes 1~ 4 accordingly.

Table 13

Table 14

For HP/LP gas pipes only
