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 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.

** Kit 51W11 is provided with a 1-1/2” accelerator which must be for all 2 and 2-1/2” PVC installations.
+ Termination kits 44W92 and 44W93 are approved for use in Canadian installations to meet CSAB149.
++ The 44W92 Concentric kit is provided with a 1-1/2” accelerator, which must be installed on the exhaust outlet when this kit is used
with this furnace.
NOTE
: When using 1-1/2” piping and terminating with a flush mount kit or concentric kit, the pipe must be transitioned to 2” pipe
before attaching to the flush mount kit or the concentric kit.
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.
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 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.
