(2)Use vertical condensate leg of distributor only. Do not over-tighten clamp.

(3)Drip stations on steam mains must be located at all low points in the system, at each elevation change and or directional change.

(4)Horizontal runs of steam must have a 2" rise per foot (10°) when flow is going away from drip station and the steam run is to fall ½" per foot (2°) when flow is going towards drip station.

(5)In a horizontal run of the steam main, drip stations must be located at regular intervals of 20 feet.

(6)The drip station itself is a section of piping connected to the bottom of the main. A full size tee must be used to create a drip station to allow the condensate to fall in the drip station.
