Introduction

Chimney top devices are used throughout the world and to provide clearer guidance, the NFPA 211 Technical Committee would like to develop a clearer vision of the international use of chimney top devices. A Fire Protection Research Foundation report entitled, Impact of Chimney-top Appurtenances on Flue Gas Flow, was previously completed in December 2014 included a look at existing chimney-top devices and their effect on the flow of gas. It also included a review of available chimney-top devices. However, it did not consider international implications. This project reviewed international codes and standards as they pertain to the use of chimney top devices. 

The purpose of the project, which is documented in this report, was to provide a review of the current requirements and the prescribed application of chimney top devices throughout international codes and standards for solid-fuel, oil-burning and gas-burning chimney/vent systems which includes fireplaces and heat producing appliances.
