Scope 1.1 This Code applies to the installation of appliances, equipment, components, and accessories where oil is used for fuel purposes in applications that include (a) space heating; (b) service water heating; (c) power generation; and (d) process application. 1.2 This Code provides minimum requirements for installing or altering all stationary and portable oil-burning equipment, including (a) furnaces; (b) process furnaces; (c) boilers; (d) water heaters; (e) vehicle heaters; (f) construction heaters; and (g) internal combustion engines when used for power applications in buildings. Note: For installation of internal combustion engines for emergency power applications, see also CAN/CSA-C282 and CSA Z32. Both these Standards refer to CSA B139 for installation of accessories such as fuel tanks and piping. 1.3 This Code provides minimum requirements for installing or altering ancillary equipment, including (a) piping and tubing systems supplying fuel oil-burning equipment; (b) pumps; (c) control devices; (d) venting systems; (e) accessories; (f) heat distribution systems that affect the proper operation of the oil-burning equipment; (g) central oil distribution systems; and (h) above-ground storage tanks that have a maximum individual capacity of 2500 L (550 gal) and a maximum aggregate capacity of 5000 L (1100 gal). Note: Underground fuel oil tank installations of any size and above-ground installations over 2500 L (550 gal) are covered by the National Fire Code of Canada (NFCC) and the CCME Environmental Code. Storage tank installations might also be governed by requirements of the authority having jurisdiction. 1.4 This Code provides requirements for the maintenance of the most commonly used types of oil-burning equipment. 1.5 This Code provides recommended precautions for filling tanks (see Annex G). 1.6 This Code does not apply to (a) process equipment installed in refineries; (b) appliances installed in mobile housing, recreational vehicles, and marine craft; (c) portable devices such as lamps, blowtorches, melting pots, and weed burners; or (d) integral fuel tanks on internal combustion engines. Note: For installation of oil-burning equipment in mobile housing and recreational vehicles, see CAN/CSA-Z240 MH Series. 1.7 In CSA Standards, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; "may" is used to express an option or that which is permissible within the limits of the standard; and "can" is used to express possibility or capability. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.8 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
