Installation - Lennox EL296UHV Series Unit Information

II-PLACEMENT AND INSTALLATION
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 the TABLE 21 below for approved piping and fittings

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.
EL296UHV exhaust and intake connections are made
of PVC. Use PVC primer and solvent cement when
D1785
using PVC vent pipe. When using ABS vent pipe, use
F891
transitional solvent cement to make connections to the
D2466
PVC fittings in the unit.
F441
Use PVC primer and solvent cement or ABS solvent ce-
F438
ment meeting ASTM specifications, refer to Table 2. As an
D2241
alternate, use all purpose cement, to bond ABS, PVC, or
CPVC pipe when using fittings and pipe made of the same
F442
materials. Use transition solvent cement when bonding
F628 ABS to either PVC or CPVC.
Low temperature solvent cement is recommended during
D1527
cooler weather. Metal or plastic strapping may be used for
D2468
vent pipe hangers. Uniformly apply a liberal coat of PVC
primer for PVC or use a clean dry cloth for ABS to clean
D2661
inside socket surface of fitting and male end of pipe to
depth of fitting socket.
D2665
Canadian Applications Only - Pipe, fittings, primer and
solvent cement used to vent (exhaust) this appliance must
ASTM
be certified to ULC S636 and supplied by a single manu-
SPECIFICATION
facturer as part of an approved vent (exhaust) system. In
F656
addition, the first three feet of vent pipe from the furnace
D2564
flue collar must be accessible for inspection.
