Marks for UL Gas Fired Equipment Certification Service

These marks indicate a product’s compliance to nationally recognized gas standards, including UL, ANSI Z21/Z83 Series and CSA/CGA standards. Products carrying these marks have been evaluated to reasonably foreseeable hazards including both gas and electrical hazards.
