Kit # NAHA001CV & NAHA002CV
For Concentric Vent Termination information call 931.270.4100
with the complete model and serial number of the furnace.
Refer to Special Venting Requirements for Installations in Canada
in the Vent and Combustion Air Connections Section.
These kits are for vertical or horizontal termination of the
combustion air inlet and the exhaust vent pipes on Category IV
gas−fired condensing furnaces. The NAHA001CV kit can be used
for 3" (76.2mm) diameter pipe systems. The NAHA002CV kit can
be used for 2" (50.8mm) diameter pipe system. Refer to Table 5
for the correct pipe size for the furnace. Both the combustion air
inlet and the exhaust vent pipes must attach to the termination kit.
The termination kit must terminate outside the structure and must
be installed per the instructions outlined below for vertical or

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
(76.2mm) vents.
NOTE: The minimum vent length is 54 (1.5m) of PVC. Feet of
pipe is whichever pipe run is the longest, either inlet or
outlet side.
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.
