Frequently Asked Questions

  • Yes — this burner will not work without fire glass, and the glass is not included in the base purchase. For the 30-inch model specifically, 15 lbs of decorative glass media is required, which typically means ordering two bags. You can choose from regular fire glass, reflective fire glass, or fire gems in a variety of colors.

  • This insert is designed to fit into an existing wood-burning fireplace, a dedicated ventless firebox enclosure, or a new custom fire feature build — for both indoor and outdoor use. It cannot be installed in a factory-built fireplace whose instructions prohibit unvented gas logs. For indoor installations, the maximum BTU allowed is calculated using the formula: Length × Width × Height × 20.

  • The G21-series burner used in this 30-inch set delivers up to 35,000 BTUs on natural gas, providing meaningful supplemental heat for a room. Because it is a vent-free appliance, all heat stays in the room rather than being lost up a chimney, making it an efficient zone-heating solution. BTU output may vary slightly with propane, so confirm the spec for the fuel type you select.

  • The unit includes a pre-assembled Oxygen Depletion System (ODS) pilot, which automatically shuts the burner off before room oxygen levels drop below 18%, protecting occupants from unsafe air quality. The burner is also ANSI-certified and constructed from 304 stainless steel for durability and clean burning. Per the manufacturer's manual, annual cleaning of the burner and ODS pilot by a qualified professional is required to maintain safe operation.

  • Robert H. Peterson Co. (RH Peterson) warrants the vent-free burner component parts for 10 years for indoor use and 5 years for outdoor use. The decorative fire glass, gems, and nuggets are covered for 5 years, while valves, ODS pilots, and controls carry a 1-year limited warranty. The warranty applies to the original purchaser for residential use in the U.S. or Canada and requires proof of purchase.
