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.
 DANGER
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.
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.
NOTE: Time  is  critical  at  this  stage.  Do  not  allow 
primer to dry before applying cement.
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.
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 
an  improper  defective  assembly  due  to  insufcient 
solvent.
9.  Handle joints carefully until completely set.
