Placement & Installation
Pipe & Fittings Specifications
All pipe, fittings, primer and solvent cement must conform
with American National Standard Institute and the American
Society for Testing and Materials (ANSI/ASTM) standards.
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, stratification,
or separation that cannot be removed by stirring. Refer to
Table 8 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.
CAUTION
GDD92C
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.
IMPORTANT
Use PVC primer and solvent cement or ABS solvent
cement meeting ASTM specifications, refer to Table 8.
As an alternate, use all purpose cement, to bond ABS,
PVC, or CPVC pipe when using fittings and pipe made of
the same materials. Use transition solvent cement when
bonding ABS to either 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
inside socket surface of fitting and male end of pipe to
depth of fitting socket.
NOTE:
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)
system. In addition, the first three feet of vent pipe from the
furnace flue collar must be accessible for inspection.
