The best indoor linear gas fireplace depends on whether you need a wide contemporary flame display, a particular firebox size, or a vent-free installation. The Bluegrass Living 48-inch model is best for buyers seeking a natural-gas linear fireplace with LED lighting and a programmable remote. Empire’s 36-inch and 60-inch Boulevard models offer other linear vent-free options. The Duluth Forge insert and stove are non-linear alternatives for shoppers prioritizing different formats.
| Product | Best For | Fuel or Format |
|---|---|---|
| Bluegrass Living Envision 48-Inch | Linear design with LED accents and remote control | Natural gas, vent-free |
| Empire Boulevard 36-Inch | A smaller linear fireplace option | Natural gas, vent-free |
| Empire Boulevard 60-Inch | A wider contemporary linear display | Natural gas, vent-free |
| Duluth Forge 32,000 BTU Insert | A vent-free insert with two fuel options | Natural gas or propane |
| Duluth Forge 25,000 BTU Stove | A freestanding stove-style alternative | Ventless gas stove |
Bluegrass Living Envision 48-Inch Linear Fireplace
The Bluegrass Living Envision is a vent-free, natural-gas linear fireplace with a 48-inch format. Its listed heat output is up to 37,000 BTUs. The product features LED lighting and shimmering fireglass intended to accentuate the flame display.
Best for: Buyers who want a mid-size linear gas fireplace with decorative lighting and remote operation. The included full-function programmable variable remote can operate the fireplace, and the product description says it eliminates the need for a standing pilot.
Why it stands out: This is the most clearly specified option for shoppers seeking a linear natural-gas fireplace with contemporary fireglass and LED effects. It does not require an outside duct or chimney, according to the listing.
Limitation: It operates on natural gas only, so it is not the choice for a propane-only home. Confirm that vent-free gas appliances are permitted for the intended location before choosing it.
Empire Boulevard 36-Inch Linear Fireplace
The Empire Boulevard is a 36-inch natural-gas linear fireplace with a vent-free design. Its contemporary burner creates the firebox display. The listing describes vent-free construction as offering more installation flexibility than vented units and says the fireplace can be placed in homes where venting is not possible.
Best for: Buyers looking for a smaller linear fireplace format than the 48- or 60-inch options in this guide. It may suit a room or wall design where a wider fireplace is not practical.
Why it stands out: The product lists multiple ignition options: intermittent pilot ignition or millivolt ignition. Check the specific configuration before buying, because the listing describes options rather than confirming one universal setup.
Limitation: The supplied product information does not state a BTU output or include detailed dimensions beyond the 36-inch designation. Confirm the exact specifications and installation requirements for the selected model.
Empire Boulevard 60-Inch Contemporary Fireplace
This Empire Boulevard is a 60-inch contemporary linear vent-free fireplace for natural gas. Its listed features include multicolor programmable LED lighting under the burner, a thermostat variable remote control, an in-wall lighting control module, and a battery-backup module with a stainless switch cover.
Best for: Buyers who want a wider linear display and programmable lighting. The 60-inch size is the largest of the listed linear gas models, making it the better fit when a broader fireplace opening is part of the design plan.
Why it stands out: The product information specifically identifies both under-burner multicolor lighting and a thermostat variable remote. These features distinguish it from models whose listings emphasize flame presentation or general remote operation.
Limitation: The provided details do not specify heat output, ignition type, or complete installation dimensions. Verify those details and the required clearances before planning a wall opening.
Duluth Forge Dual-Fuel Ventless Fireplace Insert
This Duluth Forge product is a ventless fireplace insert, not a linear fireplace. It is included as an alternative for shoppers whose priority is a gas insert and fuel flexibility rather than a contemporary linear shape. The listing specifies 32,000 BTUs and operation with either natural gas or liquid propane.
Best for: Buyers who need a dual-fuel insert with a remote control. The included remote has an LCD screen for turning the burner on or off, and the unit has manual flame adjustment.
Why it stands out: Its listed fuel choice is a meaningful distinction from the natural-gas-only linear fireplaces above. The listing also says no outside duct or chimney is needed and describes heating up to 1,500 square feet.
Limitation: This is an insert with realistic faux logs and a mesh screen, not a sleek linear firebox. Treat the stated coverage as listing information, not a guarantee of performance in every home.
Duluth Forge 25,000 BTU Ventless Gas Stove
The Duluth Forge QSL250T is a ventless gas stove rather than a linear fireplace. It has a listed output of 25,000 BTUs and thermostat-operated control with variable heat settings. Its hand-painted concrete logs are designed to resemble real wood.
Best for: Buyers who prefer a stove-style appearance and adjustable thermostat control over a long, low linear flame presentation. The listing states that the unit heats up to 1,100 square feet.
Why it stands out: It offers a distinct format among the products in this comparison. Its thermostat control allows users to select variable heat settings, according to the product details.
Limitation: This is not a linear fireplace, and the supplied listing describes it as a propane fireplace despite the product name referring to natural gas. Confirm the exact fuel configuration before purchase.
Buying Guide: How to Choose an Indoor Linear Gas Fireplace
Do you need a linear model or a different fireplace format?
A linear fireplace has a wide, horizontal firebox appearance. The Bluegrass Living and Empire Boulevard products in this guide are the direct matches for that style. The Duluth Forge insert and stove are included only as alternatives: one is an insert with faux logs, and the other is a stove-style appliance.
Decide on the format before comparing decorative details. A linear unit is intended to create a contemporary horizontal focal point, while an insert or stove presents a different look and may be intended for a different installation plan. Confirm the product’s dimensions and installation method for your project.
Which fireplace size fits your wall?
The listed linear choices are 36, 48, and 60 inches. A 36-inch model may be worth considering when the available opening or design calls for a more compact unit. The 48-inch Bluegrass Living model offers a middle size, while the 60-inch Empire option is the widest listed linear product.
Do not select a fireplace based only on its nominal width. Check the manufacturer’s complete dimensions, framing requirements, clearances, and installation instructions. The supplied product details do not provide all of these measurements.
Is the fireplace natural gas, propane, or dual fuel?
Fuel type is a primary filter. The Bluegrass Living Envision is listed for natural gas only. The Empire Boulevard linear listings are also identified as natural-gas products. The Duluth Forge insert is described as dual fuel for natural gas or liquid propane.
Do not assume a fireplace can be converted to another fuel because a different model offers that option. Confirm the exact product configuration and available household fuel before ordering, and consult a qualified professional about gas connections.
What does vent-free mean?
A vent-free or ventless gas appliance is described as not requiring an outside duct or chimney. That feature can affect installation flexibility, but it does not mean every room or home is suitable. Requirements and restrictions can vary by jurisdiction and installation location.
Before choosing a vent-free fireplace, check local codes, the product manual, and applicable building requirements. Ask a qualified installer to assess whether the appliance can be installed in the intended space. Follow all manufacturer instructions for operation and maintenance.
How much heat output do you need?
Compare the listed BTU output, but do not treat a BTU figure as a complete measure of comfort or suitability. The Bluegrass Living model lists up to 37,000 BTUs, while the Duluth Forge insert lists 32,000 BTUs and the stove lists 25,000 BTUs. The supplied details do not state BTUs for either Empire linear model.
Room layout, insulation, climate, and other factors affect heating needs. Ask an installer or heating professional to help determine whether a specific appliance is appropriate for the space rather than relying only on a stated square-foot coverage figure.
Which controls and flame effects matter?
Compare controls based on how you plan to use the fireplace. The Bluegrass Living model includes a programmable variable remote. The Empire 60-inch model lists a thermostat variable remote and programmable multicolor LED lighting. The Empire 36-inch listing describes ignition choices, so verify the configuration available for the specific unit.
Lighting and fire media affect appearance, not just operation. Bluegrass Living lists LED lighting and shimmering fireglass. Empire’s 60-inch model specifies multicolor lighting under the burner. Choose the features that suit the room while confirming what is included with the selected configuration.
