Preface:This is the third edition of CSA/ANSI Z83.26 • CSA 2.37,Gas-fired outdoor infrared patio heaters. It supersedes the previous editions published in 2014 and 2007.The third edition of this Standard has been updated to reflect current industry practice and address CSA Group?s guide on drafting Standards. Major changes to this edition include the following:a) Replace references to liquefied petroleum (LP) gas with propane to clarify that other forms of LP gas are not intended to be used.b) Increase in maximum input rating to 24 000 Btu/hr.c) Distinction between a tabletop heater and a patio heater not for tabletop use.d) New Annex D, which permits manufacturers to offer gas field conversion kits for heaters using both natural and propane gas.e) New Annex E, which addresses installations at altitudes over 2000 ft (610 m).f) Existing coverage from ANSI Z21.103 added to address appliances using two one-pound cylinders with CGA 600 connectors.g) Existing coverage from CSA/ANSI Z21.10.1 • CSA 4.1 added to allow the use of two automatic gas valves to be used in a series to control the main burner gas instead of a single manual valve.h) Existing coverage from ANSI Z21.58 • CSA 1.6 added and adapted to address failure of the products to function under wind conditions.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.This Standard has been approved by the American National Standards Institute (ANSI) as an American National Standard.Scope:1.1This Standard applies to newly produced gas-fired outdoor infrared patio heaters (see Clause 3) hereinafter referred to as "heaters" or "appliances", constructed entirely of new, unused parts and materials for use with:a) natural gas; orb) propane.1.2The heaters covered by this Standard are intended for installation in and heating of residential or nonresidential spaces.1.3Infrared patio heaters may be suspended overhead, angle-mounted overhead, wall-mounted, floor-mounted or for tabletop use.1.4Patio heaters intended for tabletop use are those limited to input ratings of 24 000 Btu/hr (7034 W) or less. These units incorporate an integral self-contained propane gas supply system consisting of a maximum of two disposable 1 lb (0.45 kg) fuel capacity cylinders and operating at pressures not greater than 5 psi (34.5 kPa).1.5Infrared patio heaters not intended for tabletop use may be for connection toa) a fixed fuel piping system operating at inlet gas pressures not exceeding 1/2 psi (3.5kPa); orb) an integral self-contained propane gas supply system, provided the appliance incorporates mounting means for the attachment of a maximum of one cylinder limited to a maximum of 20 lb (9.1 kg) of fuel operating at regulated outlet withi) pressure not exceeding 11 in wc (2.74 kPa); orii) pressures in excess of 11 in wc (2.74 kPa) but not greater than 5 psi (34.5 kPa).1.6Clause 2 contains a list of standards specifically referenced in this Standard and sources from which these reference standards may be obtained.1.7Special construction provisions applicable to an appliance designed for use with an optional listed conversion kit are outlined under Annex D.1.8Special construction provisions applicable to infrared heaters designed to operate at altitudes over 2000 ft (610 m) are outlined in Annex E.1.9If a value for measurement as given in this Standard is followed by an equivalent value in other units, the first stated value is to be regarded as the specification.This Standard contains SI (Metric) equivalents to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM-SI-10 is used as a guide in making metric conversion from yard/pound quantities.) If a value is given for a measurement and an equivalent value in other units, the first stated is to be regarded as the requirement. The given equivalent value may be approximate. If a value for a measurement and an equivalent value in other units are both specified as a quoted marking requirement, the first stated unit, or both shall be provided.1.10In this Standard, "shall" is used to express a requirement, i.e., a provision that the user shall 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.
