SL 26-260 G3

Intake/Exhaust Maximum Equivalent Length

45° elbow allow 3 ft for each elbow

PP 87-90° elbows allow 8 ft for each elbow

3-inch Stainless Sidewall

Terminal IBC (P-257)

Intake:No additional allowance required

Exhaust:Allow 20 ft

3-inch PP flexible pipe Limited to a maximum of 60 ft

Allow 3.3 x actual length (e.g., 10 feet of 3-inch flexible pipe

x 3.3 = 33 feet of rigid pipe)

SL 40-399 G3

Intake/Exhaust Maximum Equivalent Length

4-inch rigid pipe 200 ft (each side)

90° elbow allow 8 ft for each elbow

90° long sweep elbow allow 5 ft for each elbow

45° elbow allow 3 ft for each elbow

PP 87-90° elbows allow 8 ft for each elbow

3-inch Stainless Sidewall Terminal

(SST) IBC P-257

Intake:No additional allowance required

Exhaust:Allow 65 ft

3-inch CPVC (to adapt to the SST) for each 1 ft allow 3.2 ft equivalent

4-inch PP flexible pipe Limited to 160 ft maximum

Allow 1.2 x actual length (e.g., 10 feet of 4-inch flexible

pipe x 1.2 = 12 feet of rigid pipe)

Notes

Unused intake travel cannot be added to the exhaust. Unequal intake and exhaust

piping is allowed.

Support should be provided for intake and vent piping, particularly for horizontal runs

(follow local code).
