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, accessory concentric vent termination kits and accessory
external drain trap available from the furnace manufacturer have
been certified to ULC S636 for use with those Royal Pipe and
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 – GVS-65 Primer (Purple) for
Royal Pipe or IPEX System 636, PVC/CPVC Primer, Purple
Violet for Flue Gas Venting and GVS-65 PVC Solvent Cement for
Royal Pipe or 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
CAN/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
ventilation 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 ventilation des gaz, ses accessoires, le terminal
concentrique mural ainsi que l’ensemble du drain de condensation
extérieur fourni par le fabricant de cette fournaise ont été certifiés
ULCS 636 pour l’application des composantes Royal Pipe, IPEX
PVC qui sont certifiées à ce standard. Au Canada, l’apprêt et le
ciment doivent être du même fabricant que le système
d’évacuation. L’apprêt GVS-65 (Purple) et le ciment-solvant
GVS-65 doivent être utilisé avec les Royal Pipe. Système IPEX
636, apprêt PVC/CPVC, Purple pour évacuation des gaz de
combustion et
système IPEX 636(1)t, ciment PVC pour
évacuation des gaz de combustion, coté classe IIA, 65 deg C.
doivent être utilisés avec le système d’évacuation IPEX 636 – Ne
pas combiner l ’apprêt et le ciment d’un manufacturier avec un
système d’évacuation d’un manufacturier différent.
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 CAN/CSA B149
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.
CARBON MONOXIDE POISONING HAZARD
Failure to follow the steps outlined below for each appliance
connected to the venting system being placed into operation
could result in carbon monoxide poisoning or death.
The following steps shall be followed for each appliance
connected to the venting system being placed into operation,
while all other appliances connected to the venting system are
not in operation:
1. Seal any unused openings in venting system.
2. Inspect the venting system for proper size and
horizontal pitch, as required in the National Fuel Gas
Code, ANSI Z223.1/NFPA 54 or the CSA B149 Nat-
ural Gas and Propane Installation Code and these in-
structions. Determine that there is no blockage or
restriction, leakage, corrosion and other deficiencies,
which could cause an unsafe condition.
3. As far as practical, close all building doors and
windows and all doors between the space in which the
appliance(s) connected to the venting system are
located and other spaces of the building.
4. Close fireplace dampers.
5. Turn on clothes dryers and any appliance not
connected to the venting system. Turn on any exhaust
fans, such as range hoods and bathroom exhausts, so
they are operating at maximum speed. Do not operate
a summer exhaust fan.
6. Follow the lighting instructions. Place the appliance
being inspected into operation. Adjust the thermostat
so appliance is operating continuously.
7. Test for spillage from draft hood equipped appliances
at the draft hood relief opening after 5 minutes of
main burner operation. Use the flame of a match or
candle.
8. If improper venting is observed during any of the
above tests, the venting system must be corrected in
accordance with the National Fuel Gas Code, ANSI
Z223.1/NFPA 54 and/or CSA B149.1 Natural Gas
and Propane Installation Code.
9. After it has been determined that each appliance
connected to the venting system properly vents when
tested as outlined above, return doors, windows,
exhaust fans, fireplace dampers and any other
gas--fired burning appliance to their previous
conditions of use.

WARNING
General
If this furnace replaces a furnace that was connected to a vent
system or chimney, the vent or vent connectors of other remaining
appliances may need to be re--sized. Vent systems or vent
connectors of other appliances must be sized to the minimum size
as determined using appropriate table found in the current edition
of National Fuel Gas Code NFPA 54/ANSI Z--223.1. In Canada,
refer to CAN/CSA--B149.1.
An abandoned masonry chimney may be used as a raceway for
properly
insulated
and
supported
combustion--air (when
applicable) and vent pipes. Each furnace must have its own set of
combustion--air and vent pipes and be terminated individually, as
shown in Fig. 55 for Direct Vent (2--Pipe) system, or Fig. 56 for
single--pipe or ventilated combustion air option.
A furnace shall not be connected to a chimney flue serving a
separate appliance designed to burn solid fuel.
Other gas appliances with their own venting system may also use
the abandoned chimney as a raceway providing it is permitted by
