UL listings commonly found with wood burning and electric hearth products are not used with gas hearth systems. Instead, all tested and listed gas hearth systems will have a corresponding ANSI standard. To explain, UL stands for Underwriters Laboratories, which is an agency that provides product testing for various products. While many products will have a UL standard, any number of testing agencies may have performed the product testing to that standard. Any of the wood burning fireplaces we offer will have a UL listing, but the testing agency used to attain that standard may have been PFS Corp, Omni or Underwriters Laboratories. To help provide clarity, this sample installation manual
for an electronic ignition outdoor firepit insert reflects a product that has been safety-tested and listed to ANSI Z21.97-2010 ACR97-003 by CSA International.
