KGAVT0801CVT - 35′ (10.7m) & (4) 90° elbows

with 3″ (76.2mm) PVC pipe

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″ (50.8mm) and 3″ (76.2mm) vents.

If more than four elbows are required, reduce the length of both the inlet and exhaust pipes 5′ (1.5m)for each additional elbow used.

*Feet of pipe is whichever pipe run is the longest, either inlet or outlet side.

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″(1524mm). (See Fig. 33.)

Do not use field supplied couplings to extend the pipes. Airflow restriction will occur and the furnace pressure switch may cause intermittent operation.

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 Fig. 34.

b.Cement the rain cap to the shortest of the straight kit parts. (See Fig. 34.)

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 Fig. 34.)

Drill clearance hole in rain cap and pilot hole in vent pipe.

!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 gasses to be recirculated.

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.

!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 gasses may occur. Water may also collect inside the larger combustion air pipe and flow to the burner enclosure.

7.Secure the assembly to the structure as shown in Fig. 32 or Fig. 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 Fig. 32 for vertical termination. Ensure the termination location clearance dimensions are as shown in Fig. 35 and Fig. 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 Fig. 32 or Fig. 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.
