CSA B214-12

Abstract

This Code sets out the minimum provisions for the installation, extension, alteration, and renewal of hydronic heating systems. <br>This Code applies to open and closed hydronic heating systems. These systems include <br>(a) hydronic space heating; <br>(b) radiant heating (wall, floor, ceiling); <br>(c) convectors; <br>(d) fan coils; <br>(e) combination potable water heating and space heating (combo) systems; <br>(f) integrated mechanical systems; <br>(g) indirect-fired domestic water heating; <br>(h) pool and spa heating; <br>(i) snow melt systems; and <br>(j) other auxiliary systems. <br>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; and "may" is used to express an option or that which is permissible within the limits of the standard. <br>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. <br>Notes to tables and figures are considered part of the table or figure and may be written as requirements. <br>Annexes are designated normative (mandatory) or informative (nonmandatory) to define their application. <br>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.
