Cutting the field supplied gas pipes
Use the following tables in case dimension A is 318 mm (refer to
"Dimensions for installation" on page 11
If dimension A exceeds 318 mm, extend the L dimension of the gas
pipes 1~3 and HP/LP gas pipes 1~4 accordingly.
■
For suction gas pipes only
For L dimension of suction gas pipes 1~3, dimension B of the
field supplied angled joint as in table 25 on page 11 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 1~3 accordingly.
