High-Intensity Infrared Heater Safety and Performance: A Guide to ANSI Z83.19-2017 / CSA 2.35-2017
Essential technical requirements and compliance insights for gas-fired high-intensity infrared heaters in commercial and industrial applications.
Scope and Application of ANSI Z83.19-2017
The ANSI Z83.19-2017 / CSA 2.35-2017 standard defines the comprehensive requirements for the construction, performance, and safe operation of gas-fired high-intensity infrared heaters. These heaters are characterized by the incandescent nature of their burner surfaces, typically operating at temperatures exceeding 800 °C (1470 °F). They are widely used for spot heating, space heating, and process heating in commercial, industrial, and agricultural environments.
The standard distinguishes itself from standards governing low-intensity systems (ANSI Z83.20) by focusing on direct radiant heat transfer from a highly heated surface rather than convective heat transfer from a duct or tube system. It applies to both vented and unvented configurations intended for indoor and outdoor installation, covering multiple gas categories including natural gas, propane, and manufactured gas.
Key Distinction: High-intensity heaters regulated by ANSI Z83.19 achieve immediate radiant output upon ignition because the burner surface itself is the primary radiant source, unlike low-intensity tube heaters which require a warm-up period to heat the emitting tube.
