Empire Boulevard Vent-Free 36-in Natural Gas Linear IP Fireplace
The Empire Boulevard offers a vent-free, energy-efficient design ideal for spaces without venting. Best for: homeowners seeking installation flexibility and realistic gas firebox visuals without a chimney. It supports multiple ignition options, including intermittent pilot or millivolt ignition, and provides a contemporary burner that creates a striking display. Caution: vent-free systems rely on indoor air circulation; ensure proper room sealing and follow local codes for installation.
LegendFlame Austin Build in Electric Fireplace 72″
LegendFlame Austin is a large in-wall electric unit with a realistic flame effect and two flame coloration options. Best for: large living rooms or open-plan spaces where a dramatic electric display is desired. Features include multiple flame combinations, five brightness levels, and a built-in heater with two heat settings (though not intended as a primary heat source). A limitation is that it requires electrical installation and is not a gas insert, so it won’t provide true gas flame ambiance.
Touchstone Sideline 50″ Wide In-Wall Electric Fireplace
Touchstone Sideline provides a modern in-wall electric experience with realistic flames and multiple ember options. Best for: rooms where a ventless, electric heat source with smart features is preferred. It includes remote control operation and can run with or without heat. Limitation: it is electric, so it depends on household power and may require stud framing and safe mounting practices for in-wall installation.
PuraFlame Klaus Electric Fireplace Insert
PuraFlame Klaus combines a glass-door insert with a three-sided brick interior for a classic look and realistic embers. Best for: users seeking a traditional visual without the mess of wood or gas. It offers three flame settings and can be used with or without heat. Limitation: being electric, it relies on power, and the unit’s dimensions fit certain fireplace openings; verify fit before purchase.
Stanbroil Linear 60″ Fire Pit Pan
Stanbroil offers an outdoor fire pit pan designed for natural gas or propane, with a high flame output. Best for: outdoor entertainment spaces requiring a robust flame presence. It supports LP or NG fuel and includes upgrade options for increased flame. Caution: outdoor use requires proper weatherproofing and gas line safety, and a propane setup may need an air mixer valve.
Buying Guide
Key considerations for selecting a linear fireplace insert include fuel type, installation location, heat output, and ambiance options.
- Gas vs Electric: Gas inserts provide authentic flame visuals and continuous heat, while electric units offer easy installation and flexible placement without venting concerns.
- Ventilation: Vent-free gas inserts require sufficient room air and adherence to local codes. Electric models avoid venting but rely on electrical supply and may have lower heating output.
- Size and opening: Measure the fireplace opening to ensure a proper fit. Larger walls benefit from wide inserts like the 72″ electric unit, while compact spaces suit 36″ options.
- Controls and features: Remote thermostats, multiple flame colors, and dimming options enhance mood and efficiency. Some units offer smart features (Alexa/WiFi) for convenience.
- Outdoor suitability: For outdoor or semi-outdoor spaces, choose fire pit pans or weather-resistant inserts designed for exterior use.
- Safety and installation: If mounting in-wall, ensure studs and clearances meet building codes. Professional installation is recommended for gas lines and electrical work.
Frequently Asked Questions
- What is a vent-free gas fireplace insert?
A vent-free gas insert operates without a chimney or vent, releasing combustion byproducts into the room, so proper ventilation and room size are important.

Most operate on standard household outlets, but high-wattage models may need a dedicated circuit or professional electrical wiring.
- Can these inserts be installed in existing fireplaces?
Many electric models are designed for in-wall or insert installation, while gas vent-free models require appropriate venting and clearances per code.

Gas units may require periodic sensor and burner checks, while electric units mainly need dusting and filter care (where applicable).
