Direct--Vent Upflow

Variable--Capacity Condensing Gas Furnace

For Sizes 060--120, Series C

Installation, Start--Up and

Operating Instructions

Visit www.Bryant.com

NOTE

: Read the entire instruction manual before starting the installation.

NOTE

:

This furnace can be installed as a

(2-pipe) direct vent or as an optional ventilated combustion air

application.

NOTE

: 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

(1)

t

, 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 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
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

(1)

t

, ciment pour PVC pour conduit en

évacuation des gaz, 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. 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.
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.
