Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of gas-fired low-intensity infrared heaters. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on gas-fired low-intensity infrared heaters designed for utilization of gas. There are risks of injury to persons inherent in appliances that, if completely eliminated, would defeat the utility of the appliance. The provisions in this standard are intended to help reduce such risks while retaining the normal operation of the appliance.

1.1 Scope

1.1.1
This standard applies to newly produced, gas-fired low-intensity infrared heaters and infrared radiant tube heaters (see Part IV, 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/hr (117.23 kW) per burner:
a. For use with natural gas;
b. For use with manufactured gas;
c. For use with mixed gas;
d. For use with liquefied petroleum (propane) gases;
e. For use with LP gas-air mixtures; and
f. Convertible for use with natural gas and liquefied petroleum (propane) gases, when provision is made for the simple conversion from one gas to the other.

1.1.2
The 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.

1.1.3
Low-intensity infrared heaters and infrared radiant tube 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 Part IV, Definitions.

1.1.4
Overhead heaters complying with this standard are suitable for use in (1) aircraft hangars when installed in accordance with the Standard for Aircraft Hangars, ANSI/NFPA 409, and (2) garages when installed in accordance with the Standard for Parking Structures, ANSI/NFPA 88A, or the Standard for Repair Garages, ANSI/NFPA 88B, or the Canadian Natural Gas and Propane Installation Code, CSA B149.1, and are so marked.

1.1.5
The heaters covered by this standard may be:
a. Designed for connection to a vent; or
b. Not designed for connection to a vent.

1.1.6
The construction and performance of heaters covered by this standard are specified in Parts I and II, respectively. The definitions for certain terms used are in Part IV, Definitions.

1.1.7
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.

1.1.8
All references to “psi” are to be considered gage pressures unless otherwise specified.

1.1.9
Exhibit A, Items Unique to the United States, contains provisions that are unique to the United States.

1.1.10
Exhibit B, Items Unique to Canada, contains provisions that are unique to Canada.

1.1.11
Exhibit D, List of Reference Standards, contains a list of standards specifically referenced in this standard, and sources from which these reference standards may be obtained.
