About Open Hearth Co

Open Hearth Co is a Canadian reference archive focused on fireplace and wood stove safety for residential property owners. The material here covers WETT inspection requirements, creosote accumulation and removal, hearth clearance distances, and chimney relining options — the four areas that generate the most questions from homeowners managing wood-burning systems.

What This Resource Covers

The content here draws on published Canadian and North American standards — CSA B365, ULC S635, NFPA 211, and provincial building code amendments — along with publicly available guidance from WETT Inc., Natural Resources Canada, and Environment and Climate Change Canada.

The focus is residential properties. Commercial and industrial chimney applications are outside the scope of this archive.

What This Resource Is Not

Nothing published here constitutes a formal WETT inspection, a building permit application, legal advice, or a professional recommendation tied to any specific property. For an inspection that carries insurance or permit value, a WETT-certified technician must assess the system in person. For questions about local code compliance, the authority having jurisdiction (AHJ) for your municipality is the definitive source.
