Joint Cementing Procedure - Lennox Allied Air A96UHMV Installation Instructions Manual

Joint Cementing Procedure

All cementing of joints should be done according to the
specifications outlined in ASTM D2855.
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.
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.

6. Promptly apply solvent cement to end of pipe and inside
socket surface of fitting. Cement should be applied
lightly but uniformly to inside of socket. Take care to
keep excess cement out of socket. Apply second coat
to end of pipe.
NOTE: Time is critical at this stage. Do not allow primer to
dry before applying cement.
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 during
assembly (but not after pipe is fully inserted) to distribute
cement evenly. DO NOT turn ABS or cellular core pipe.
NOTE: Assembly should be completed within 20 seconds
after last application of cement. Hammer blows should not
be used when inserting pipe.
8. After assembly, wipe excess cement from pipe at end
of fitting socket. A properly made joint will show a bead
around its entire preimeter. Any gaps may indicate a
defective asembly due to insufficient solvent.
9. Handle joints carefully until completely set.
