CAN ULC-S629-2016 PDF Download

The CAN ULC-S629-2016 standard is a national standard in Canada that applies to factory-built chimney assemblies. These assemblies are specifically designed for use with residential appliances and building heating equipment that use gas, liquid, or solid fuels. The standard specifies that the flue-gas temperatures should not exceed 650 ºC.

These factory-built chimneys are intended to be used both inside and outside of buildings. Their primary role is to provide a vertical conduit or passageway for safely conveying flue gases from the aforementioned appliances to the outer air. The purpose of this standard is to ensure the safe and effective operation of these chimney assemblies by providing guidelines and specifications for their construction, installation, and usage.
