Sierra Flame

Yes, Sierra Flame gas fireplaces are compatible with both natural gas and liquid propane (LP). Most models are available in either fuel type at the time of purchase, and Sierra Flame also sells fuel conversion kits that allow you to switch between natural gas and propane by adjusting the gas valve opening to accommodate the different BTU output of each fuel type.

Heating output varies by model, but Sierra Flame gas fireplaces typically range from around 18,000 BTU/h on low to up to 38,000 BTU/h on high, with many popular models like the Bennett 45 outputting around 30,000 BTU/h. Larger models such as the Austin 65 on liquid propane can heat up to approximately 700 square feet, making them effective for zone heating in living rooms and open-plan spaces.

Sierra Flame gas fireplaces come with a 5-year limited warranty covering defects in materials and workmanship, including combustion chambers, heat exchangers, burners, and stainless steel parts against tarnishing. Electrical components and wearable parts such as blowers, gas valves, remote controls, and igniters are covered for 1 year, during which Sierra Flame will provide replacement parts free of charge.

Yes, Sierra Flame gas fireplaces are direct vent units that use a sealed coaxial venting system, and installation should be performed by a licensed gas professional to ensure safety and code compliance. The design is built with ease of installation in mind — no concrete board or special metal studs are required, and combustible wood and drywall materials can be finished around the unit — but a certified technician must handle the gas line connection and venting.

Sierra Flame was founded by Brian Richards and is the sister brand of Amantii, both of which draw on nearly four decades of experience in the fireplace and heating industry. The brand is globally recognized and trusted by designers, architects, and builders, with all units built using high-quality components including an 18–20 gauge steel body and stainless steel burners.
