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 030, 045 and 070 input models. When using 1-1/2 inch vent pipe, transition to 2" pipe before installing
concentric kit.
3
Flush mount kits 51W11 and 51W12 includes 1-1/2 in. outdoor exhaust accelerator, required when used with 030, 045, 070 and 090 input models.. . When using 1-1/2 in. piping, the pipe
must be transitioned to 2 in. pipe when used with the Flush Mount Kit
4
Termination kits 30G28, 44W92, 4493 and 81J20 are certified to ULC S636 for use in Canada only.
5
See table 16 for vent accelerator requirements.
6
2 inch to 1-1/2 inch reducer required, must be field provided.
Joint Cementing Procedure
All cementing of joints should be done according to the
specifications outlined in ASTM D 2855.
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 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 in­
side socket surface of fitting. Cement should be ap­
plied lightly but uniformly to inside of socket. Take
care to keep excess cement out of socket. Apply sec­
ond 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 dur­
ing assembly (but not after pipe is fully inserted) to dis­
tribute cement evenly. DO NOT turn ABS or cellular
core pipe.
