Preface

This publication represents a basic standard for safe operation, substantial and durable construction, and acceptable performance of portable type gas camp heaters. It is the result of years of experience in the manufacture, testing, installation, maintenance, inspection and research on portable type gas camp 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.

The revisions in this edition supersedes any corresponding provisions of ANSI Z21.63-2000/CSA 11.3-2000, ANSI Z21.63a-2001/CSA 11.3a-2001, and ANSI Z21.63b-2003/CSA 11.3-2003 and are identical to the coverage from the review and comment texts dated November 2005 and March 2009. No changes were made to the review and comment texts, therefore there is no Appendix.
