The best ventless gas fireplace surround depends on whether you need an insert for an existing opening, a recessed installation, or a complete fireplace with a mantel. The Duluth Forge 32,000-BTU dual-fuel inserts suit buyers who want remote operation and natural gas or propane flexibility; the Duluth Forge propane insert is designed for a customizable recessed look; and the Comfort Glow offers a complete ventless fireplace option with remote controls. Compare fuel type, heating output, and what the product listing says is included before choosing.

Duluth Forge FDI32R Dual-Fuel Insert
Best for: Buyers who want an insert-style fireplace with a remote and the option to use natural gas or liquid propane. Its 32,000-BTU output is listed for heating areas up to 1,500 square feet. The maker describes it as 99.9% efficient and says it requires no outside duct or chimney.
The remote has an LCD screen and can turn the burner on and off. The listing also describes manual flame adjustment, nine hand-painted ceramic fiber logs, and a mesh screen. This combination makes the FDI32R a relevant choice for buyers comparing a traditional log appearance with remote operation.
Why it was selected: It is directly identified as a ventless fireplace insert, provides dual-fuel flexibility, and includes specific control and log details useful when planning a surround.
Consideration: This is an insert, not a listed mantel package. Confirm the opening and surround plan separately, and verify that the intended fuel is supported by the installation instructions.
Duluth Forge FDF400RT-ZC Fireplace Insert
Best for: Buyers who want a dual-fuel insert with visible doors and a brick-style liner as part of the fireplace’s appearance. The unit is rated at 32,000 BTU and is listed to heat up to 1,500 square feet. It is designed for natural gas or liquid propane.
The remote has an LCD screen for switching the burner on and off, and the listing notes a standing pilot and manual flame adjustment. Six hand-painted ceramic fiber logs, mesh double doors, and a sprayed brick liner provide more built-in visual detail than a plain insert listing.
Why it was selected: Its insert format and finished interior details make it a practical candidate for buyers coordinating a fireplace surround and firebox appearance.
Consideration: The product information does not specify a mantel as included. Treat the doors and liner as described features, not as a substitute for checking the dimensions and finish requirements of your planned surround.
Duluth Forge Liquid Propane Fireplace Insert
Best for: Buyers who use liquid propane and want an insert described for recessed or face-mantel installation. The listing calls its design customizable and says it can be recessed into a wall or paired with a face mantel for a built-in look.
This model produces up to 26,000 BTU and is listed to heat spaces up to 1,350 square feet. It includes five hand-painted ceramic fiber logs and a dual precision-ported burner. The product description presents it as a ventless option that does not require a chimney.
Why it was selected: Its recessed-design language makes it especially relevant to shoppers searching for a ventless gas fireplace surround rather than a freestanding stove or log set.
Consideration: This model is listed for liquid propane, not natural gas. Choose it only if that fuel matches your home’s setup and the product’s installation requirements.
Duluth Forge DFS-400R-2AS With Mantel
Best for: Buyers who want a fireplace system and mantel together instead of sourcing a surround separately. The listing describes a furniture-grade mantel in an Apple Spice finish, with light distressing and burnished edges, plus double doors and a sprayed brick liner.
The unit uses natural gas or liquid propane and is rated at 32,000 BTU, with heating listed for up to 1,500 square feet. It includes a remote with an LCD screen and offers manual or thermostat control. Six hand-painted ceramic fiber logs complete the fireplace’s stated appearance.
Why it was selected: Unlike insert-only options, this listing explicitly includes a mantel, which makes it a direct match for shoppers comparing complete surround-style packages.
Consideration: A furniture-style mantel has a defined finish and appearance. Check the product dimensions and room layout before choosing it, particularly if you need a specific surround width, height, or color.
Comfort Glow GFD4605R Ventless Fireplace
Best for: Buyers looking for a ventless fireplace with a thermostatic remote and concealed controls. The listing specifies 33,000 BTU of heating capacity for spaces up to 1,200 square feet and says no chimney is required.
The ash-gray fireplace has remote operation and discreet controls, according to the product details. Its stated heating area is smaller than the 1,500-square-foot claims for the two Duluth Forge 32,000-BTU inserts, so compare the listed coverage with the room or zone you plan to heat rather than choosing on output alone.
Why it was selected: It provides another ventless fireplace format and a remote-control option for shoppers who are comparing alternatives to insert-only products.
Consideration: The listing says the remote requires four AAA batteries and that they are not included. Check the product’s installation details to determine how it fits your intended surround.
Buying Guide: How to Choose a Ventless Gas Fireplace Surround
Do you need an insert, a mantel package, or a recessed design?
Start with the type of installation you want. An insert is intended to sit within a planned fireplace opening or surround. A fireplace package that explicitly includes a mantel can simplify matching the firebox and surround, while a recessed-design product may suit a built-in appearance. Do not assume that a product described as an insert includes a mantel or surround; check the exact listing and installation documentation.
Measure the planned opening and available wall area before selecting a model. Compare the manufacturer’s dimensions and required clearances with your space. The product information provided here does not give complete installation dimensions, so use the detailed product documentation rather than estimating from images.
Which fuel type should you choose?
Fuel compatibility can narrow the options quickly. The FDI32R, FDF400RT-ZC, DFS-400R-2AS, and Comfort Glow listings describe dual-fuel operation. The Duluth Forge recessed-design insert is listed for liquid propane. Confirm the appliance’s approved fuel and connection requirements before purchase; do not assume a natural-gas-only or propane-only product can be converted.
For dual-fuel models, verify which fuel configuration is appropriate for your home and whether the supplied setup meets the manufacturer’s instructions. Have fuel-line and appliance work handled according to local requirements by a qualified professional.
How much heating output and coverage do you need?
Compare both BTU output and the stated coverage area. The selected products list outputs from 26,000 to 33,000 BTU and coverage claims from 1,200 to 1,500 square feet. These figures are product claims, not a guarantee that a fireplace will heat every room of that size equally. Room layout, insulation, ceiling height, and open doorways affect how heat moves through a home.
A fireplace may be more appropriate for zone heating than for replacing a whole-home heating system. Choose based on the room where you expect to use it, and follow the manufacturer’s guidance for the intended space.
What control and appearance features matter?
Remote control can be useful if you want to operate the burner from across the room. Some listed models also specify thermostat control or manual flame adjustment. Check the exact controls for the model you are considering: remote operation, thermostat settings, and flame adjustment are not interchangeable features.
Appearance varies as well. The product details mention ceramic fiber logs, mesh screens, double doors, brick-style liners, and a furniture-grade mantel. Decide whether you want a simpler insert face or a more finished fireplace presentation. A listed mantel finish may not match every room, while a separate surround gives more freedom but requires planning.
What should you check before installing a ventless fireplace?
“Ventless” or “vent free” means the listed product does not require an outside duct or chimney as described by its manufacturer; it does not remove the need to follow installation, ventilation, and use instructions. Check local building and fuel-appliance rules before buying because requirements can vary by location. Confirm the installation clearances and room-use guidance in the manual.
Also verify what is included in the box, what additional materials may be needed, and whether the product fits the planned surround. Do not base installation decisions on product photographs alone. Use the manufacturer’s documentation and consult a qualified installer where required.
Frequently Asked Questions
Does a ventless gas fireplace need a chimney?
The products in this selection are described as ventless or as requiring no chimney or outside duct. Follow the specific model’s installation instructions and local requirements; “ventless” does not mean installation rules can be skipped.
Can a ventless fireplace insert use natural gas or propane?
Some selected models are listed as dual fuel, while the Duluth Forge recessed-design insert is listed for liquid propane. Check the exact model’s stated fuel type before purchase and do not assume that all inserts accept both fuels.
Does a fireplace insert include a surround or mantel?
Not necessarily. The DFS-400R-2AS listing explicitly describes a fireplace with a mantel. The other insert listings do not state that a mantel is included, so confirm the package contents before planning the surround.
How do I compare heating capacity?
Compare the listed BTU output and coverage area, then consider your room layout and the manufacturer’s instructions. The selected products claim coverage between 1,200 and 1,500 square feet, but actual heat distribution depends on the space.
Are batteries included with the remote?
The Comfort Glow listing says its remote requires four AAA batteries and that they are not included. The other product details provided do not specify battery inclusion, so check each model’s package information.
