3.Working from furnace to outside, cut pipe to required length(s).
4.Deburr inside and outside of pipe.
5.Chamfer outside edge of pipe for better distribution of primer and cement.
6.Clean and dry all surfaces to be joined.
7.Check dry fit of pipe and mark insertion depth on pipe.
NOTE: It is recommended that all pipes be cut, prepared, and preassembled before permanently cementing any joint.
8.After pipes have been cut and preassembled, apply generous layer of cement primer to pipe fitting socket and end of pipe to insertion mark. Quickly apply approved cement to end of pipe and fitting socket (over primer). Apply cement in a light, uniform coat on inside of socket to prevent buildup of excess cement. Apply second coat.
9.While cement is still wet, twist pipe into socket with 1 /4 turn. Be sure pipe is fully inserted into fitting socket.
10.Wipe excess cement from joint. A continuous bead of cement will be visible around perimeter of a properly made joint.
11.Handle pipe joints carefully until cement sets.
