This is the third edition of ANSI Z83.19/CSA 2.35, Gas-fired high intensity infrared heaters. It supersedes the previous editions published in 2009 and 2001.
This Standard applies to newly produced, gas-fired high-intensity infrared heaters (see Clause 3, Definitions), hereinafter referred to as heaters or appliances, constructed entirely of new, unused parts and materials with inputs up to and including 400,000 Btu per hour (117 228 W) per burner:
a) for use with natural gas;
b) for use with manufactured gas;
c) for use with mixed gas;
d) for use with propane gas;
e) for use with LP gas-air mixtures; or
f) convertible for use with natural gas and propane gas, when provision is made for the simple conversion from one gas to the other.
Heaters covered by this Standard are intended for installation in and heating of outdoor spaces or nonresidential indoor spaces and are intended for location where flammable gases or vapors are not generally present.
Although heaters covered by this Standard may, in certain instances, be suitable for application in industrial processes, this Standard does not cover industrial process burners.
High-intensity infrared heaters may be suspended overhead, angle mounted overhead, wall mounted, or floor mounted. Floor-mounted heaters may be free-standing and, when for outdoor installation, also may be portable to the extent defined in Clause 3, Definitions.
Overhead heaters complying with this Standard are suitable for use in:
a) aircraft hangars when installed in accordance with the Standard for Aircraft Hangars, NFPA 409; and
b) garages when installed in accordance with the Standard for Parking Structures, NFPA 88A, or the Standard for Repair Garages, NFPA 88B; or the Canadian Natural Gas and Propane Installation Code, CSA B149.1, and are so marked.
The heaters covered by this Standard may be:
a) designed for connection to a vent; or
b) not designed for connection to a vent.
The construction and performance of heaters covered by this Standard are specified in Clauses 4 and 5, respectively. The definitions for certain terms used are in Clause 3, Definitions.
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.
All references to psi are to be considered gauge pressures unless otherwise specified.
Special construction provisions applicable to an appliance designed for use with an optional listed conversion kit are outlined under Annex C, (Optional) Provisions for listed gas appliance conversion kits.
Annex A, Items Unique to the United States, contains provisions that are unique to the United States.
Annex B, Items Unique to Canada, contains provisions that are unique to Canada.
Special construction provisions applicable to an appliance designed for use with an optional listed conversion kit are outlined under Annex C, (Optional) Provisions for Listed Gas Appliances Conversion Kits.
Clause 2, Reference Publications, contains a list of standards specifically referenced in this Standard, and sources from which these reference standards may be obtained.
In 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.
