Automatic Valves for Gas Appliances
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
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
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
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.
