1. Do not include the field supplied 45° elbow in the total elbow
count.
2. If more than four elbows are required, reduce the length of
both the inlet and the exhaust pipes five feet for each
additional elbow used.
3. Elbows are DWV long radius type for 2
NOTE: Feet of pipe is whichever pipe run is the longest, either
inlet or outlet side.

count.

both the inlet and the exhaust pipes five feet for each

3. Elbows are DWV long radius type for 2
NOTE: Feet of pipe is whichever pipe run is the longest, either

5. Partially assemble the concentric vent termination kit.
Clean and cement the parts using the procedures for
Joining Pipe and Fittings section of the manual. A) Cement
the Y Concentric fitting to the longest of the two straight kit
pipes. (See Figure 31) B) Cement the rain cap to the
shortest of the straight kit parts. (See Figure 31) NOTE: A
field supplied stainless steel screw may be used to secure
the rain cap to the pipe instead of cementing when field
disassembly is desired for cleaning (See Figure 34)
If assembly needs to be extended to meet height or side wall
thickness requirement, the two pipes supplied in the kit may be
replaced by using the same diameter solid, single (no coupling
connections) field supplied SDR--26 PVC (ASTM D2241) pipes.
Do not extend dimension D more than 60". (See Figure 33)
32
Do not use field supplied couplings to extend the pipes.
Airflow restriction will occur and the furnace pressure switch
may cause intermittent operation.

WARNING
!
CARBON MONOXIDE POISONING HAZARD.
Failure to follow this warning could result in
personal injury or death.
When using the alternate screw assembly method,
drill a clearance hole in the rain cap and a pilot hole
in the vent pipe for the screw size being used.
Failure to drill adequate holes may cause cracking
of the PVC components, allowing flue gases to be
recirculated.
WARNING
!
CARBON MONOXIDE POISONING HAZARD.
Failure to follow this warning could result in
personal injury or death.
Do not operate the furnace with the rain cap
removed as recirculating of the flue gases may
occur. Water may also collect inside the larger
combustion air pipe and flow to the burner
enclosure.
6. Install the Y concentric fitting and the pipe assembly through
the structure's hole. For vertical termination, install the parts
through the field supplied roof boot/flashing. NOTE: Do not
allow insulation or other materials to accumulate inside the
pipe assembly when installing through the structure's hole.
7. Secure the assembly to the structure as shown in Figure 32
or Figure 36 using field supplied metal strapping or
equivalent material.
NOTE: Ensure the termination height is above the roof
surface or anticipated snow level as shown in Figure 32 for
vertical termination. Ensure the termination location
clearance dimensions are as shown in Figure 35 and
Figure 36 for horizontal termination.
8. Install the rain cap and the small diameter pipe assembly in
the Y concentric fitting and the large pipe assembly. Ensure
that the small diameter pipe is bottomed out and securely
cemented in the Y concentric fitting.
9. Cement the furnace combustion air and vent pipes to the
concentric vent termination assembly. See Figure 32 or
Figure 36 for proper pipe attachment.
10. Operate the furnace through one heat cycle to ensure
combustion air and vent pipes are properly connected to the
concentric termination connections.
Drill clearance hole in rain
cap and pilot hole in vent pipe.
