unit operates properly and safely. Use fiberglass sealing
strips, caulking, or equivalent sealing method between the
plenum and the furnace cabinet to ensure a tight seal. If
a filter is installed, size the return air duct to fit the filter
frame.
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 2 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
A95UH1D / A93UH1D / 95G1UHD / 92G1UHD 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.

Joint Cementing Procedure
All cementing of joints should be done according to the
specifications outlined in ASTM D 2855.
NOTE:
A sheet metal screw may be used to secure the
intake pipe to the connector, if desired. Use a drill or self
tapping screw to make a pilot hole.
