Joint Cementing Procedure - Lennox ELITE Series Installation Instructions Manual

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
adversely affects the joint strength or chemical resistance
of the cement. The cement shall show no gelation, strati-
fication, or separation that cannot be removed by stirring.
Refer to TABLE 2 below 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.
EL296UHE 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.
D1785
F891
Use PVC primer and solvent cement or ABS solvent ce-
D2466 ment meeting ASTM specifications, refer to TABLE 2.
As an alternate, use all purpose cement, to bond ABS,
F441
PVC, or CPVC pipe when using fittings and pipe made of
F438
the same materials. Use transition solvent cement when
bonding ABS to either PVC or CPVC.
D2241
Low temperature solvent cement is recommended during
F442
installation in cooler weather. Metal or plastic strapping
may be used for vent pipe hangers. Uniformly apply a lib-
F628
eral 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.
D2468
Canadian Applications Only - Pipe, fittings, primer and
solvent cement used to vent (exhaust) this appliance must
D2661
be certified to ULC S636 and supplied by a single manu-
facturer as part of an approved vent (exhaust) system. In
D2665
addition, the first three feet of vent pipe from the furnace
flue collar must be accessible for inspection.

Fumes from PVC glue may ignite during system check.
Allow fumes to dissipate for at least 5 minutes before
placing unit into operation..

CAUTION
IMPORTANT
1 - Measure and cut vent pipe to desired length.
2 - Debur and chamfer end of pipe, removing any ridges
or rough edges. If end is not chamfered, edge of pipe
may remove cement from fitting socket and result in
a leaking joint.
NOTE - Check the inside of vent pipe thoroughly for
any obstruction that may alter furnace operation.
3 - Clean and dry surfaces to be joined.
4 - Test fit joint and mark depth of fitting on outside of
pipe.
5 - 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.
