Joint Cementing Procedure
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.
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.
NOTE:
Check the inside of vent pipe thoroughly for any
obstruction that may alter furnace operation.
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.

NOTE
- Standard Terminations do not include any vent pipe or elbows external to the structure. Any vent pipe or elbows external to the structure must be included in total
vent length calculations. See vent length tables.* Kits must be properly installed according to kit instructions.
1. Requires field-provided outdoor 1-1/2” exhaust accelerator.
2. Concentric kits 71M80 and 44W92 include 1-1/2” outdoor accelerator, when used with 045 and 070 input models. When using 1-1/2 in. piping, the pipe must transition to
2 in. pipe when used with the concentric kit.
3. Flush mount kits 51W11 and 51W12 includes 1-1/2 in. outdoor exhaust accelerator, required when used with 045, 070 and 090 input models. When using 1-1/2 in.
piping, the pipe must transition to 2 in. pipe when used with the flush mount kit.
4. Termination kits 44W92 and 44W93 are certified to ULC S636 for use in Canada only.
5. See table 10 for vent accelerator requirements.
6. 2 inch to 1-1/2 inch reducer required. must be field required.
