Joint Cementing Procedure

All cementing of joints should be done according to the specifications outlined in ASTM D 2855.

NOTE − A sheet metal screw may be used to secure the intake pipe to the connector, if desired. Use a drill or self tapping screw to make a pilot hole.

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.

3 − Clean and dry surfaces to be joined.

NOTE − Check the inside of vent pipe thoroughly for any obstruction that may alter furnace operation.

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 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.

NOTE − Time is critical at this stage. Do not allow prim- er 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 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.

8 − After assembly, wipe excess cement from pipe at end of fitting socket. A properly made joint will show a bead around its entire perimeter. Any gaps may indi- cate a defective assembly due to insufficient solvent.

9 − Handle joints carefully until completely set.
