Scope:

1.1 These requirements apply to Factory-Built Type A Chimneys, which do not require field fabrication. They are for use with gas and liquid fuel-fired residential appliances and building heating equipment, where the appliance or equipment flue-gas temperatures do not exceed 540 °C. They are intended for use in accordance with the National Building Code of Canada, CSA-B139.2, Installation Code for Oil Burning Equipment for Residential and Small Commercial Buildings, and CSA-B149.1, Natural Gas and Propane Installation Code. They are intended for installation inside or outside of buildings to provide an essentially vertical conduit or passageway for conveying flue gases to the outer air from the above-described class of appliances.

Project need:

ULC-S604 would benefit from some minor technical and editorial edits to update the standard's format with current ULC Standards practices. It has been proposed to remove edition dates from the Reference Publications sections as has been standard practice on newer ULC Standards development activities.
