Standard Spotlight: CAN/ULC-S627:2021

The Fourth Edition of CAN/ULC-S627, Standard for Space Heaters for Use with Solid Fuels, was published as a National Standard of Canada in May 2021. This Edition of the Standard was developed by the ULC Standards Subcommittee on Solid-Fuel Burning Appliances, and was formally approved by the ULC Standards Technical Committee for Factory-Built Fireplaces, Chimneys and Vents.?

This Standard applies to hand fuelled, solid fuel fired space heaters of the radiant, convection or forced circulating air type intended for residential heating.

The following are the Sections/Subsections that were added and/or modified in this Fourth Edition of CAN/ULC-S627:

Expanded Glossary;

• The term “Mobile Home” was changed to “Transportable Building”

Addition and/or Modification of the following:

• Construction Section
• Performance Test Sections

–?????Test No. 1 – Temperature – Coal Fire Test

–?????Test No. 4 – Door Hazard Test

–?????Test No. 6 – Stability Test

• Improved formatting and document structure that renders the Standard more user-friendly.

Prior to the processing of the Fourth Edition, a Revision to the Third Edition was published during August, 2020, to address appliances that do not incorporate a catalytic combustor by-pass, so as to respond to an urgent stakeholder need, on a more rapid timeline than is typically provided by the work on a comprehensive new edition of a standard

A key in standards development is having a true consensus of people working together, not only to create new standards, but also to revise current standards to address the ever changing safety risks of the world. This was showcased in the development and publication of CAN/ULC-S627.

The ULC Standards Technical Committee for Factory-Built Fireplaces, Chimneys and Vents (S600E) consists of people from various interest groups, such as Producers, AHJs, General Interest, Supply Chain, and Testing Organizations.
