Automatic Valves for Gas Appliances
1.1 SCOPE 1.1.1 This standard applies to newly produced automatic valves (see Part VI, Definitions) constructed entirely of new, unused parts and materials. These valves may be individual automatic valves or valves utilized as parts of automatic gas ignition systems. This standard also applies to commercial/industrial safety shutoff valves (see Part VI, Definitions), herein after referred to as C/i valves. This standard shall not apply to self-contained water heater, cooking appliance, or room heater thermostats, or self-contained automatic gas shutoff valves for hot water supply systems. Components performing functions other than those of an automatic valve shall comply with applicable American National Standards or Canadian Standards. Compliance of an automatic valve with this standard does not imply that the automatic valve is acceptable for use on gas appliances without supplemental tests with the automatic valve applied to the particular appliance design. 1.1.2 The valve operator of an automatic valve may be actuated either directly or indirectly. In addition, it may be actuated by electrical means, by mechanical means, by means of a change of the absolute pressure or gas or air upon a diaphragm, or by other means. 1.1.3 This standard applies to automatic valves having maximum operating gas pressure ratings of ½, 2, 5 psi (3.5, 13.8, 34.5 kPa), or higher than 5 psi (34.5 kPa) in 5 psi (34.5 kPa) increments up to and including a maximum operating pressure of 60 psi (413.7 kPa). 1.1.4 This standard applies to automatic valves which are to be mounted in the manufacturer's specified upright position or in one or more of the optional mounting positions selected by the manufacturer. (See 2.1.1) 1.1.5 This standard applies to automatic valves which are capable of operation at ambient temperatures of 32 of 125°F (0 to 51.5°C), unless a higher temperature, lower temperature, or both, are specified by the manufacturer. (See 2.1.2.) 1.1.6 If 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. 1.1.7 All references to psi throughout this standard are to be considered gage pressure unless otherwise specified. 1.1.8 Additional provisions concerning electrical coverage applicable to units defined for use in the United States are outlined in Exhibit A. 1.1.9 Additional provisions concerning electrical coverage, instructions and markings, applicable to units destined for use in Canada are outlined in Exhibit B. 1.1.10 Exhibit C (List of Reference Standards) contains a list of standards specifically referenced in this standard and sources from which they may be obtained.
