Preface

This is the first edition of ANSI Z21.11.3-2013, Gas-fired room heaters, Volume III, Propane-fired emergency use heater systems.

Scope

1.1
This standard applies to newly-produced unvented, propane-fired portable emergency use heater systems utilizing a self-contained propane supply in a listed composite cylinder. This appliance is not for use with line voltage. A portable emergency use heater system shall be identified as a “heater system” when the coverage refers to the heating appliance and the listed composite cylinder. The term “heater” shall be used when identifying the appliance only.

A propane-fired portable emergency use heater system shall be constructed entirely of new, unused parts and materials. Propane-fired portable emergency use heater systems shall have input ratings up to and including 15,000 Btu/hr (4 396 W).

a) Heater systems listed for use in bedrooms (during emergencies) shall have a maximum input setting of 10,000 Btu/hr (2 931 W); and

b) Heater systems listed for use in bathrooms (during emergencies) shall have a maximum input setting of 5,000 Btu/hr (1465 W).

1.2
The construction of the heater and heater system is covered under Clause 4.

1.3
The performance of the heater and heater system is covered under Clause 5.

1.4
A listed composite cylinder shall meet the requirements of the U.S. Department of Transportation (DOT) special permit approval process* and shall be equipped with a listed overfilling prevention device (OPD) cylinder valve with a Compressed Gas Association CGA 793 male outlet connection.

* Title 49 Code of Federal Regulations, Transportation, Part 178, Specifications for Packagings: Subpart H – Specifications for Portable Tanks; and Part 451, Testing and Approval of Containers.

1.5
A listed composite cylinder shall also meet the requirements of the Propane Education and Research Council (PERC) Fire Test* for indoor use during emergencies.

* Code Approval of Composite Propane Cylinders for Indoor Use – PERC Docket 11643.

1.6
This standard covers heater systems shipped from the factory equipped specifically for one gas only. Field conversion of gas types shall not be permitted.

1.7
Propane-fired portable emergency use heating systems shall be designed for indoor heating in buildings during emergencies.

1.8
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.

1.9
All references to psi throughout this standard are to be considered gage pressure unless otherwise specified.

1.10
Clause 2, contains a list of standards referenced in this standard and sources from which these standards may be obtained.

1.11
This standard contains SI (Metric) corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (Standard for use of the International System of Units (SI): The Modern Metric System, IEEE/ASTM SI I0 or ISO 80000-1:2009 Quantities and units- Part 1: General are used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both shall be provided.
