A95UH1D/A93UH1D/95G1UH & 92G1UH 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 fitting in the unit.
IMPORTANT
Use PVC primer and solvent cement or ABS solvent cement
meeting ASTM specifications, refer to Table 2. 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.
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. When bonding the vent system to
the furnace, use ULC S636 approved One-Step Transition
Cement to bond the pipe to the flue collar, or to bond the 90°
elbow or reducing 90° elbow to the flue collar. In addition,
the first three feet of vent pipe from the furnace flue collar
must be accessible for inspection.
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.
