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 table 20 for approved piping and fitting materials.

CAUTION
Solvent cements for plastic pipe are flammable liq-
uids and should be kept away from all sources of igni-
tion. Do not use excessive amounts of solvent ce-
ment 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.
IMPORTANT
SLP98UHV exhaust and intake connections are made
of PVC. Use PVC primer and solvent cement when us-
ing 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 20. 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. Metal or
plastic strapping may be used for vent pipe hangers. Uni-
formly apply a liberal coat of PVC primer for PVC
Canadian Applications Only
− Pipe, fittings, primer and
solvent cement used to vent (exhaust) this appliance
must be certified to ULC S636 and supplied by a single
manufacturer as part of an approved vent (exhaust) sys-
tem. In addition, the first three feet of vent pipe from the
furnace flue collar must be accessible for inspection.
Table 21 lists the available exhaust termination kits.
