CAUTION
Solvent cements for plastic pipe are flammable liq­
uids 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 ce­
ment with skin and eyes.

EL296UHV 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 con­
nections to the PVC fittings in the unit.
Use PVC primer and solvent cement or ABS solvent ce­
ment meeting ASTM specifications, refer to Table 2. 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
F891
ABS to either PVC or CPVC.
D2466
Low temperature solvent cement is recommended during
F441
cooler weather. Metal or plastic strapping may be used for
F438
vent pipe hangers. Uniformly apply a liberal coat of PVC
D2241
primer for PVC or use a clean dry cloth for ABS to clean in­
F442
side socket surface of fitting and male end of pipe to depth
F628
of fitting socket.
