Pipe & Fittings Specifications - Lennox SLP98DFV Installation Instructions Manual

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
adversely affects the joint strength or chemical resistance
of the cement. The cement shall show no gelation, strati-
fication, or separation that cannot be removed by stirring.
Refer to table 4 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.
SLP98DFV exhaust and intake connections are made
of PVC. Use PVC primer and solvent cement when
D1785 using PVC vent pipe. When using ABS vent pipe, use
transitional solvent cement to make connections to the
F891
PVC fittings in the unit.
D2466
F441
Use PVC primer and solvent cement or ABS solvent ce-
ment meeting ASTM specifications, refer to Table 4. As an
F438
alternate, use all purpose cement, to bond ABS, PVC, or
D2241
CPVC pipe when using fittings and pipe made of the same
F442
materials. Use transition solvent cement when bonding
ABS to either PVC or CPVC.
F628
Low temperature solvent cement is recommended. Metal
or plastic strapping may be used for vent pipe hangers.
D1527
Uniformly apply a liberal coat of PVC primer for PVC.
D2468
Canadian Applications Only - Pipe, fittings, primer and
D2661
solvent cement used to vent (exhaust) this appliance must
be certified to ULC S636 and supplied by a single manu-
facturer as part of an approved vent (exhaust) system. In
D2665
addition, the first three feet of vent pipe from the furnace
ASTM
flue collar must be accessible for inspection.
