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

t, ciment pour PVC pour conduit en

(1)

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.
