Scope:

1.1 These requirements apply to factory-built gas-fired package boilers having input ratings of more than 117,228 W (400,000 Btu/h), per individual combustion chamber, and intended primarily for commercial and industrial installation.

1.2 These requirements also apply to all high pressure steam and high temperature water gas-fired boiler assemblies regardless of kW (Btu/h) input.

1.3 Package boilers covered by these requirements are designed to be automatically operated without a competent attendant being constantly on duty at the burners while the appliances are in operation.

1.4 Additional installation and operation requirements are available for commercial-industrial gas-fired packaged boilers as defined by:

a) In the United States, the National Fuel Gas Code, NFPA 54, and the Liquefied Petroleum Gas Code, NFPA 58, as applicable; or

b) In Canada, the Natural gas and propane installation code, CSA B149.1, and the Code for the field approval of fuel-related components on appliances and equipment, CSA B149.3, as applicable.

Project need:

There are currently no consensus standards published in Canada for this class of packaged boiler. The new standard will permit testing of new products, as well as oversight of new installations by AHJs. This standard is intended to replace ULC/ORD-C795 and standard UL 795.

The system allows SCC-accredited Standards Development Organizations (SDOs), and members of the public, to be informed of new work in Canadian standards development, and allows SCC-accredited SDOs to identify and resolve potential duplication of standards and effort.

Individual SDOs are responsible for the content and accuracy of the information presented here. The text is presented in the language in which it was provided to SCC.
