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. 1-1/2 in. pipe must be transitioned to 2 in. when used
with a 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. 1-1/2 in. pipe must be
transitioned to 2 in. pipe when used with the flushmount kit.
4 Termination kits 30G28, 44W92, 44W93 and 81J20 are certified to ULC S636 for use in Canada only.
5 See table 8 for vent accelerator requirements.
6 2 in. pipe to 1-1/2 in. reducer required and 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
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.
