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 4 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 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.
IMPORTANT
SLP98DFV 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 cement meeting ASTM specifications, refer to Table 4. 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 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.
Table 5 lists the available exhaust termination kits.
