II-PLACEMENT AND INSTALLATION
Pipe & Fittings Specifications
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 the table 18 below for approved piping and fitting ma­
terials.
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.

EL296DFV 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 cement
meeting ASTM specifications, refer to Table 18. As an alter­
nate, use all purpose cement, to bond ABS, PVC, or CPVC
pipe when using fittings and pipe made of the same materi­
als. Use transition solvent cement when bonding ABS to ei­
ther PVC or CPVC.
Low temperature solvent cement is recommended during
cooler weather. Metal or plastic strapping may be used for
vent pipe hangers. Uniformly apply a liberal coat of PVC
primer for PVC or use a clean dry cloth for ABS to clean in­
side socket surface of fitting and male end of pipe to depth
of fitting socket.
Canadian Applications Only - Pipe, fittings, primer
and solvent cement used to vent (exhaust) this ap­
pliance must be certified to ULC S636 and supplied by a
single manufacturer as part of an approved vent (ex­
haust) system. In addition, the first three feet of vent
pipe from the furnace flue collar must be accessible for
inspection.
