Notes:
Risers are sized using a “Top” and “Base” Datum reference. A specified Top Datum Offset indicates where top of riser will be located
relative to top of cabinet. A Base Datum indicates where bottom of riser will be located relative to floor.
Upon request Omega will swage riser pipes of same pipe size for connection to units on the floor below.
Risers should insert 2 inches into the 3 inch swage connection.
Riser Length = Floor Clearance Height + Slab Thickness + 2 inch (overlap) (Rounded up to 120” or 144”).
Omega supplies two standard riser lengths, 120” (10’) and 144” (12’), to be field cut on-site.
Omega does not supply extension tailpieces or transition riser pieces for joining dissimilar piping sizes.
Risers available in Type L and Type M/DWV copper.
Condensate riser comes standard with 3/8 inch thick closed cell insulation to prevent condensation.
Optional insulation on supply and return risers is available.
