CAUTION
Solvent cements for plastic pipe are flammable liq uids 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 ce ment with skin and eyes.

IMPORTANT
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 con nections to the PVC fittings in the unit.
Use PVC primer and solvent cement or ABS solvent cement meeting ASTM specifications, refer to Table 2. As an alter nate, use all purpose cement, to bond ABS, PVC, or CPVC pipe when using fittings and pipe made of the same materi als. Use transition solvent cement when bonding ABS to ei ther PVC or CPVC.
Low temperature solvent cement is recommended during installation in 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 ap pliance must be certified to ULC S636 and supplied by a single manufacturer as part of an approved vent (ex haust) system. 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.
DANGER
DANGER OF EXPLOSION!
Fumes from PVC glue may ignite during system check. Allow fumes to dissipate for at least 5 minutes before placing unit into operation.
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.
NOTE - Time is critical at this stage. Do not allow prim er to dry before applying cement.
6 - Promptly apply solvent cement to end of pipe and in side socket surface of fitting. Cement should be ap plied lightly but uniformly to inside of socket. Take care to keep excess cement out of socket. Apply sec ond coat to end of pipe.
7 - Immediately after applying last coat of cement to pipe, and while both inside socket surface and end of pipe are wet with cement, forcefully insert end of pipe into socket until it bottoms out. Turn PVC pipe 1/4 turn dur ing assembly (but not after pipe is fully inserted) to dis tribute cement evenly. DO NOT turn ABS or cellular core pipe.
NOTE - Assembly should be completed within 20 sec onds after last application of cement. Hammer blows should not be used when inserting pipe.
