CAUTION
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.

EL196DFE exhaust and intake connections are made
of PVC. Use PVC primer and solvent cement when
using PVC vent pipe. When using ABS vent pipe, use
transitional solvent cement to make connections to the
PVC fittings in the unit.
Use PVC primer and solvent cement or ABS solvent ce-
ment meeting ASTM specifications, refer to Table 4. As an
alternate, use all purpose cement, to bond ABS, PVC, or
CPVC pipe when using fittings and pipe made of the same
D1785
materials. Use transition solvent cement when bonding
ABS to either PVC or CPVC.

Low temperature solvent cement is recommended during
D2466
cooler weather. Metal or plastic strapping may be used for
F441
vent pipe hangers. Uniformly apply a liberal coat of PVC
F438
primer for PVC or use a clean dry cloth for ABS to clean
inside socket surface of fitting and male end of pipe to
D2241
depth of fitting socket.
