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.
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

NOTE: Isolate piping at the point where it exits the outside wall or roof in order to prevent transmission of vibration to the structure.

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 join will show a bead around its entire perimeter. Any gaps may indicate an improper defective assembly due to insufficient solvent.

9.Handle joints carefully until completely set.

If this gas furnace replaces a furnace which was commonly vented with another gas appliance, the size of the existing vent pipe for that gas ap- pliance must be checked. Without the heat of the original furnace flue products, the existing vent pipe is probably oversized for the single water heater or other appliance. The vent should be checked for proper draw with the remaining appliance.
