The vent-free outdoor stainless-steel gas fired fireplace insert is the first affordable fireplace designed to resist the elements for outdoor use. The outdoor zero clearance fireplace insert uses parts and materials that are made from 304 grade stainless steel sourced in the USA. This assures a long and reliable life in the outdoor environment.

The log set is made just like our other high-end gas log sets. Each log has been carefully molded from real wood to ensure a realistic look. Then, these logs are made from concrete and are individually hand painted to provide the most realistic look possible. Paired with the included heavy-duty stainless-steel log grate, and reflective glass ember bed, the fireplace emits a mesmerizing sparkle throughout the fireplace insert.

Includes panels that are made from durable ceramic fiber. Each panel has been molded from real brick to ensure a realistic look. Then, they are individually hand painted to provide the most realistic look possible. Every detail has been designed to ensure your fireplace is the focal point of your outdoor living space.
