NAHA001CV - 35'& (4) 90° elbows with 3" 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" and 3" vents,

NOTE: 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". (See Figure 46)

Do not use field supplied couplings to extend the pipes.

Airflow restriction will occur and the furnace pressure

switch may cause intermittent operation.

Partially assemble the concentric vent termination kit. Clean and cement the parts using the procedures for Join- ing Pipe and Fittings section of the manual. A) Cement the

Y Concentric fitting to the 4" diameter kit pipe. (See Figure 47) B) Cement the 3" rain cap to the 21/2 " diameter

kit part. (See Figure 47) 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 47)

Rain Cap to Vent Pipe Assembly

Drill clearance hole in rain

cap and pilot hole in vent pipe.

Stainless steel screw (Field supplied)

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in death,

personal injury and/or property damage.

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.

CARBON MONOXIDE POISONING HAZARD

Failure to follow this warning could result in death,

personal injury and/or property damage.

Do not operate the furnace with the rain cap removed as

recirulation of the flue gases may occur. Water may also

collect inside the larger combustion air pipe and flow to the burner enclosure.

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 accu-

mulate inside the pipe assembly when installing through the structure's hole.

Secure the assembly to the structure as shown in Figure 45 or Figure 49 using field supplied metal strap- ping or equivalent material.

NOTE: Ensure the termination height is above the roof sur-

face or anticipated snow level as shown in Figure 45 for

vertical termination. Ensure the termination location clear-

ance dimensions are as shown in Figure 48 and Figure 49 for horizontal termination.
