Installation code for oil-burning equipment

his is the ninth edition of CSA B139, Installation code for oil-burning equipment. It supersedes the previous editions published in 2009, 2004, 2000, 1991, 1976, 1971, 1962, and 1957.

This edition represents a major update of the code to reflect the growing need by users to distinguish requirements for residential installations from those required for larger and more complex installations, including separate requirements specifically created for stationary engines. As a result, the new code is organized into multiple parts as follows:
 

• Part 1.0 - Large Installations. While intended for industrial, institutional, and larger commercial buildings, it can be used for any size of installation, and contains new requirements that are intended to address the needs of these more complex systems.


• Part 1.1 - Stationary Engines. This Part includes special requirements applicable to stationary engines serving generators and fire pumps, and other equipment such as large compressors.


• Part 1.2 - Special Installations. This Part collects the existing requirements for used oil burning appliances, central oil distribution facilities, construction heaters, and vehicle heaters.


• Part 2.0 - Residential Installations. This Part focuses on the requirements for smaller installations typically used in single and two-family dwellings, as well as in small commercial buildings. Most of its content is recognizable from the previous edition but has been updated and simplified to suit these installations.

Major changes to this edition includes the following:
 

• The Scope has been revised to reflect the creation of the multi-part format.


• The Reference publications now only include related installation and testing publications. Other standards or publications for products have now been organized in a new mandatory Annex A and organized based on how they are certified or tested.


• The Definitions section has been edited to remove terms that are not used in this Code. Many of the removed terms are either similar terms commonly used, or are used as defined terms in the CSA B140 Series of appliance standards; these terms have been moved to a new Glossary at the end of the Code.


• Clarification has been provided to distinguish the difference between products which are certified for use in Canada and those which may need additional requirements by authorities having jurisdiction when they adopt this Code. The introduction of the new Annex A for product standards should simplify this code adoption process.


• Where the Code describes a product or material, it now includes the reference product standard.


• In Part 1, larger storage and supply tanks are now included for installation inside of buildings, with additional protective requirements. Similarly, the requirements for larger auxiliary supply tanks for generators have been reworked, permitting higher capacities provided protective requirements are met.


• Requirements for venting of tanks have been expanded, and include both prescriptive requirements for vent lengths as well as additional design information (in Annex F).


• In Parts 1.0 and 1.1, enhanced requirements and methods are provided for installation of unlisted metal chimneys, including those used for engine exhaust systems.


• Operations and maintenance requirements have been converted to non-mandatory Annexes.
