Single Cylinder Nozzle and Piping Parameters
A single cylinder supports up to 6 flow points.
Notes:
1. Tees allowed in supply line only, maximum of 4.
2. Additional elbows are permitted on branch lines, provided linear pipe length is reduced by
corresponding equivalent length (1.3 ft per 90° elbow, 0.6 ft per 45° elbow).
For example: a 3/8” steel elbow has an equivalent length of 1.3 ft. An ADP appliance branch may use 4
elbows, provided the total linear pipe is reduced by 1.3 ft (e.g., from 5 ft to 3.7 ft). Additional pipe cannot be
added in lieu of fittings, as pipe volume limits could be exceeded.
3. Maximum 6 ft vertical rise of supply line above cylinder outlet.
4. Maximum 2 ft vertical rise of duct or plenum branch above supply line.
5. Maximum 6.75 ft linear pipe between two most remote branch tees on supply line.
6. Minimum 7 ft pipe and 3 elbows before a range w/o shelf or fryer to prevent splash.
7. Minimum of 7 ft pipe and 2 elbows before a wok to prevent splash. Furthermore, a total of 10 ft pipe,
6 elbows, and minimum of 4 flows are required in the complete pipe network.
8. Minimum 7 ft pipe and 2 elbows before a range with shelf to prevent splash. Furthermore, a total of
10 ft of pipe, 6 elbows, and a minimum of 5 flows are required in the complete pipe network.
