Joint Cementing Procedure
All cementing of joints should be done according to these 
pecications 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 tting 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 t joint and mark depth of tting 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  tting  and  male  end  of  pipe  to 
depth of tting socket.
6 -   Promptly apply solvent cement to end of pipe and 
inside socket surface  of  tting.  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 tting socket. A properly made joint will show 
a bead around its entire perimeter. Any gaps may 
indicate  a  defective  assembly  due  to  insufcient 
solvent.
9 -  Handle joints carefully until completely set.
