IMPORTANT
A97UH2E & 97G2UHE exhaust and intake connections
are made of PVC. Use PVC primer and solvent cement
when using PVC vent pipe. When using ABS vent pipe,
use transitional solvent cement to make connections to
the PVC fitting in the unit.
All cementing of joints should be done according to the
specifications outlined in ASTM D 2855.
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.
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 fitting. 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 fitting socket. A properly made joint 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.
