III-PLACEMENT AND INSTALLATION
All pipe, fittings, primer and solvent cement must conform
with American National Standard Institute and the Ameri-
can Society for Testing and Materials (ANSI/ASTM) stan-
dards. The solvent shall be free-flowing and contain no
lumps, undissolved particles or any foreign matter that ad-
versely affects the joint strength or chemical resistance of
the cement. The cement shall show no gelation, stratifica-
tion, or separation that cannot be removed by stirring. Re-
fer to TABLE 21 for approved piping and fitting materials.

Solvent cements for plastic pipe are flammable liquids
and should be kept away from all sources of ignition.
Do not use excessive amounts of solvent cement when
making joints. Good ventilation should be maintained to
reduce fire hazard and to minimize breathing of solvent
vapors. Avoid contact of cement with skin and eyes.
Fumes from PVC glue may ignite during system check.
Allow fumes to dissipate for at least 5 minutes before

of PVC. Use PVC primer and solvent cement when
using PVC vent pipe. When using ABS vent pipe, use

ment meeting ASTM specifications, refer to TABLE 21.
D2468
As an alternate, use all purpose cement, to bond ABS,
PVC, or CPVC pipe when using fittings and pipe made of
D2661
the same materials. Use transition solvent cement when
bonding ABS to either PVC or CPVC.
D2665
Low temperature solvent cement is recommended. Metal
or plastic strapping may be used for vent pipe hangers.
