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 2 below for approved piping and fittings..

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.
EL297UHV 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
D1785
transitional solvent cement to make connections to the
D2466
PVC fittings in the unit.
F441
F438
Use PVC primer and solvent cement or ABS solvent ce-
ment meeting ASTM specifications, refer to Table 2. As an
D2241
alternate, use all purpose cement, to bond ABS, PVC, or
F442
CPVC pipe when using fittings and pipe made of the same
D1527
materials. Use transition solvent cement when bonding
ABS to either PVC or CPVC.
D2468
Low temperature solvent cement is recommended during
D2661
cooler weather. Metal or plastic strapping may be used for
vent pipe hangers. Uniformly apply a liberal coat of PVC
D2665
primer for PVC or use a clean dry cloth for ABS to clean
inside socket surface of fitting and male end of pipe to
ASTM
depth of fitting socket.
SPECIFICATION
Canadian Applications Only - Pipe, fittings, primer and
F656
solvent cement used to vent (exhaust) this appliance must
be certified to ULC S636 and supplied by a single manu-
D2564
facturer as part of an approved vent (exhaust) system. In
F493
addition, the first three feet of vent pipe from the furnace
D2235
flue collar must be accessible for inspection.
