All elbows in vent and air piping must be sweep elbows ONLY. DO NOT use short-radius elbows.
Equivalent feet for elbows (USE SWEEP ELBOWS ONLY) —
deduct from max equivalent length of piping (does not apply to termination ttings).
• 7 feet per for each additional 90° sweep elbow or 45° elbow — If piping contains more than 1 elbow in air or vent piping, other than termination ttings.
Note 1:
ABS may be used for intake air.
Material abbreviations: PP = polypropylene, SS = AL29-4C stainless steel.
If using stainless pipe, provide adapters for terminations, if required.
IPEX 3” PVC concentric vent kits can be used with standard PVC pipe, ttings and cement (ANSI/ASTM D1785) except if ULC S636 compliance
is required. For ULC S636 compliance, all pipe, ttings and cement must be IPEX System 636. For UL 1738 compliance all pipe, ttings and
cement must be IPEX System 1738. If using IPEX kits, use only IPEX product code 196006 for 3” venting.
