Riser Length Sizing
To determine the riser tail piece length of a unit (unit "A").
Riser Tail Piece ( of unit A)= FF - RRH + 2" (51).
RRH: Room riser height is cabinet height + 3" (76).
Standard cabinet height is 88" (2235).
RRH= 88" (2235) + 3" (76) = 91" (2311).
FF: Floor to Floor height is the dimension from the top of the
slab above to the top of the slab below.
To determine the riser tail piece length of a unit (unit "B") that will
require riser extensions to a unit below.
Minimum Tail Piece Length (of unit "B") = slab thickness + 5" (127).
To determine riser extensions lengths see page Riser Extension Sizing.
Note: If riser length exceeds 115" (2921), riser extensions must be
used. See Riser Extension Sizing. The riser tail piece must extend
through the slab a minimum of 5" (127) to facilitate brazing. Special
care must be taken in sizing riser lengths and tail piece lengths when:
A) Riser extensions are used.
B) Floor to fl oor heights vary.
C) Slab thickness varies from fl oor to fl oor.
See Riser Arrangement for selection of top fl oor riser applications.
