Preface
This is the second edition of CSA F383, Installation of packaged solar domestic hot water systems. It replaces the previous edition, published in 1987 under the title Installation Code for Solar Domestic Hot Water Systems.
This Standard has been developed in response to the need for an updated document to reflect changes in solar hot water technology and the needs of property owners and authorities having jurisdiction. This Standard applies to the installation of packaged solar domestic hot water systems that meet the requirements of the CSA F379 Series.
This Standard does not address durability, life expectancy, or performance of equipment, as these are covered in other CSA standards.
CSA gratefully acknowledges the financial assistance provided by Natural Resources Canada, the Ontario Ministry of Energy and Infrastructure (OMEI), BC Hydro, Manitoba Hydro, and the Canadian Solar Industries Association in the development of this Standard.
This Standard was prepared by the Subcommittee on Installation of Packaged Solar Domestic Hot Water Systems, under the jurisdiction of the Technical Committee on Solar Energy and the Strategic Steering Committee on Performance, Energy Efficiency, and Renewables, and has been formally approved by the Technical Committee.
This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.
Scope
1.1
This Standard specifies requirements for the installation of packaged solar domestic hot water (SDHW) systems that meet the requirements of the CSA F379 Series.
Note: SDHW systems include those designed to
(a) provide hot water in the absence of an auxiliary water heater;
(b) preheat water for a stand-alone gas, propane, electric, or oil water heater;
(c) use gas, propane, electricity, solid fuels, or oil for auxiliary water heating in an integrated fashion; and
(d) use liquid/liquid or boiling/condensing heat transfer between the solar collectors and potable water.
1.2
This Standard does not apply to space heating equipment or to collectors designed to form part of a building's load bearing structure.
1.3
The values given in SI (metric) units are the standard. Any values given in parentheses are for information only.
1.4
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.
