CARBON MONOXIDE POISONING, FIRE AND
EXPLOSION HAZARD
Failure to follow this warning could result in
personal injury, death and/or property damage.
Inlet and outlet pipes may NOT be vented directly
above each other (standard vent terminals).

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
or Table 6 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 horizontal termination. Vertical termination is
preferred. Field supplied pipe and fittings are required to complete
the installation.

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" (50,8ram) and 3"
(76,2mm) vents,
NOTE: The minimum vent length is 5' (1.5m) of PVC. Feet of pipe
is whichever pipe run is the longest, either inlet or outlet side,
