FIRE OR EXPLOSION HAZARD
Failure to follow the safety warnings exactly could result in
serious injury, death or property damage. Never test for
gas leaks with an open flame. Use a commercially available
soap solution made specifically for the detection of leaks
to check all connections. A fire or explosion may result
causing property damage, personal injury or
AVERTISSEMENT
RISQUE D'INCENDIE OU D'EXPLOSION
Si les consignes de sécurité ne sont pas suivies à la
lettre, cela peut entraîner la mort, de graves blessures
ou des dommages matériels. Ne jamais vérifier la
présence de fuites de gaz au moyen d'une flamme nue.
Vérifier tous les raccords en utilisant une solution
savonneuse commerciale conçue spécialement pour la
détection de fuites. Un incendie ou une explosion
risque de se produire, ce qui

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 the 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 Natural Gas and
Propane Installation Code, CSA B149.1 and these
instructions. 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 Natural Gas and Propane
Installation Code, CSA B149.1.
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.
AVERTISSEMENT
RISQUE D'INTOXICATION AU MONOXYDE DE
CARBONESi
appareil
les étapes décrites ci-dessous ne sont pas
suivies pour chacun des appareils raccordés au système
de ventilation au moment de sa mise en marche, cela
peut entraîner une intoxication au monoxyde de
carbone ou la mort. Les étapes suivantes doivent être
suivies pour chacun des appareils raccordés au système
de ventilation au moment de sa mise en marche, alors
que tous les autres appareils raccordés au système de
ventilation ne sont pas en marche :
1) Sceller toutes les ouvertures inutilisées du système de
ventilation.
2) Inspecter le système de ventilation afin de vérifier si
la taille et l'inclinaison par rapport à l'horizontale sont
conformes aux exigences du National Fuel Gas Code,
ANSI Z223.1/NFPA 54 ou du Code d'installation du gaz
naturel et du propane, CSA B149.1 et à ces instructions.
Vérifier qu'il n'y a pas d'obstruction ou de restriction, de
fuite, de corrosion et d'autres problèmes qui pourraient
entraîner une situation dangereuse.
3) Si possible, fermer toutes les portes et fenêtres du
bâtiment ainsi que toutes les portes séparant l'endroit
où se trouvent les appareils raccordés au système de
ventilation et les autres zones du bâtiment.
4) Fermer le registre des foyers.
5) Mettre les sécheuses en marche ainsi que tous les
autres appareils qui ne sont pas raccordés au système
de ventilation. Mettre en marche tous les ventilateurs
de tirage, comme celui des hottes de cuisine et des
salles de bains, et les régler à la puissance maximale. Ne
pas mettre en marche les ventilateurs d'été.
6) Suivre les instructions d'allumage. Mettre en marche
l'appareil soumis à l'inspection. Régler le thermostat de
manière à ce que l'appareil fonctionne en continu.
7) Vérifier la présence de fuite au niveau de l'ouverture
du coupe-tirage des appareils qui en sont dotés après 5
minutes de fonctionnement du brûleur principal. Utiliser
la flamme d'une allumette ou d'une bougie.
8) Si un problème de ventilation est observé pendant
l'un des essais décrits ci-dessus, des correctifs doivent
être apportés au système de ventilation conformément
au National Fuel Gas Code, ANSI Z223.1/NFPA 54 et (ou)
au Code d'installation du gaz naturel et du propane, CSA
B149.1.

RISQUE D'EMPOISONNEMENT AU MONOXYDE DE CARBONE
Le monoxyde de
des
carbone peut causer des maladies graves telles que
dommages permanents au cerveau et meme la mort.
Cette ventilation est nécessaire pour éviter le danger d'intoxication
au CO pouvant survenir si un appareil produisant du monoxyde
de carbone continue de fonctionner au sein de la zone confinée.
