Vent Termination Clearances
WARNING
!
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).
1.
Determine termination locations based on clearances
specified in following steps and as shown in Figure 8,
Figure 31 through Figure 36.
2.
The vent termination must be located at least 12"
(304.8mm) above ground or normally expected snow
accumulation levels.
3.
Do NOT terminate over public walkways. Avoid areas
where condensate may cause problems such as above
planters, patios, or adjacent to windows where steam may
cause fogging.
4.
The vent termination shall be located at least 4' (1219mm)
horizontally from any electric meter, gas meter, gas
regulator, and any relief equipment. These distances apply
ONLY to U.S. installations.
5.
The vent termination is to be located at least 3' (914mm)
above any forced air inlet located within 10' (3m); and at
least 10' (3m) from a combustion air intake of another
appliance, except another direct vent furnace intake.
6.
In Canada, the Canadian Fuel Gas Code takes precedence
over the preceding termination instructions.

Special Venting Requirements for Installations in Canada
Installation in Canada must conform to the requirements of CSA
B149 code. Vent systems must be composed of pipe, fittings,
cements, and primers listed to ULC S636. The special vent
fittings and accessory concentric vent termination kits and
accessory external drain trap have been certified to ULC S636
for use with those IPEX PVC vent components which have
been certified to this standard.
cement must be of the same manufacturer as the vent system −
IPEX System 636, PVC/CPVC Primer, Purple Violet for Flue
Gas Venting and IPEX System 636
Gas Venting, rated Class IIA, 65 deg C. must be used with this
venting system − do not mix primers and cements from one
manufacturer with a vent system from a different manufacturer.
Follow the manufacturer's instructions in the use of primer and
cement and never use primer or cement beyond its expiration
date.
The safe operation, as defined by ULC S636, of the vent
system is based on following these installation instructions, the
vent system manufacturer's installation instructions, and proper
use of primer and cement. All fire stop and roof flashing used
with this system must be UL listed material. Acceptability under
Canadian standard CSA B149 is dependent upon full
compliance with all installation instructions.
standard, it is recommended that the vent system be checked
once a year by qualified service personnel.
The authority having jurisdiction (gas inspection authority,
municipal building department, fire department, etc) should be
consulted before installation to determine the need to obtain a
permit.

Consignes spéciales pour l'installation de ventillation au
Canada
L'installation faite au Canada doit se conformer aux exigences
du code CSA B149. Ce systême de ventillation doit se
composer de tuyaux, raccords, ciments et apprêts conformes
au ULC S636.
La tuyauterie de ventillation des gaz, ses
accessoires,
le
terminal
l'ensemble du drain de condensat extérieur ont été certifiés
ULCS 636 pour l'application des composantes IPEX PVC qui
sont certifiées à ce standard. Au Canada l'apprêt et le ciment
doivent être du même manufacturier que le systême de
ventillation − IPEX Système 636, Apprêt PVC/CPVC. Mauve

636
t, ciment pour PVC pour conduit en évacuation des gaz,
(1)
évalué CLASSE IIA, 65 deg. C. doit ëtre utilisé avec ce
systèeme d'évacuation − ne pas mélanger l'apprêt et le ciment
d'un manufacturier avec le systême de ventillation d'un autre
manufacturier. Bien suivre les indications du manufacturier lors
de l'utilisation de l'apprêt et du ciment et ne pas utiliser ceux−ci
si la date d'expiration est atteinte.
L'opération sécuritaire, tel que définit par ULC S636, du
système de ventilation est basé sur les instructions d'installation
suivantes, ainsi que l'usage approprié de l'apprêt et ciment.
Tout arrët feu et solin de toit utilisés avec ce système doivent
être des matériaux listés UL.
Canadien CSA B419 est directement relié à l'installation
conforme aux instructions ci− haut mentionnées. Le standard
Canadien recommande l' inspection par un personel qualifié et
ce, une fois par année.
Les autoritées ayant juridiction (inspecteurs de gas, inspecteurs
en bâtiments, département des incendies, etc) devraient être
consultées avant l'installation afin de déterminer si un permis
est requis.

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 4
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.
