1.1 Application
This Standard provides minimum requirements for oil-burning equipment, including
a) fuel oil filters;
b) draft regulators;
c) flue pipe mounted heat reclaimers;
d) through-the-wall venting systems;
e) systems that supply outside combustion air; and
f) used-oil-burning equipment.
1.2 Intended use
This Standard is to be used in conjunction with the other Standards in the CSA B140 series, as applicable, to form a complete Standard for a particular type of oil-burning appliance or equipment.
1.3 Correlation with the CSA B140 series of Standards
Each of the other Standards in the CSA B140 series covers construction requirements, marking, instructions, and detailed testing procedures for a single classification or a closely related group of oil-burning equipment.
1.4 Units of measurement
The values given in SI (metric) units are the units of record for the purpose of this Standard. The values given in parentheses are for information and comparison only.
1.5 Terminology
In this Standard, “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; and “may” is used to express an option or that which is permissible within the limits of the Standard.
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.
