CONDENSING GAS FURNACE
SIZES 060---120, SERIES A
NOTE: Read the entire instruction manual before starting
the installation.
NOTE: This furnace can be installed as a
(2-pipe) direct vent
or (1-pipe) non-direct vent
condensing gas furnace.
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. In Canada, the primer and 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, PVC Cement for Flue 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. Under this 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 b e
consulted before installation to determine the need to obtain a
permit.
Consignes spéciales pour l’installation d e ventillation au Canada
L’installation faite au Canada doit se conformer aux exigences du
code CSA B149. Ce systême d e ventillation doit se composer de
tuyaux, raccords, ciments et apprêts conformes au ULC S636. La
tuyauterie de ventillation des gaz, ses accessoires, le terminal
concentrique mural ainsi que 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 Violette pour conduit en évacuation des gaz
et IPEX Système 636, ciment pour PVC pour conduit en
évacuation des gaz, évalué CLASSEIIA,65deg.C.doitëtre
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. L’acceptation du standard 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.
Some Provinces may require the combustion air system to be
ULC-- S636 certified.
