3.4.3 Fixation of Manifold
(1) There must be three fixing point for both horizontal and vertical installation of the Y-type
manifold.
Fixing point 1: 100 mm on the main inlet manifold from the welding point.
Fixing point 2: 200 mm on the main branched pipe from the welding point.
Fixing point 3: 250 mm on the branched pipe from the welding point.
