The best propane gas fireplace option depends on whether you need a complete insert or logs for an existing firebox. The Duluth Forge FDI32R is best for shoppers seeking a dual-fuel ventless insert, while the 24-inch Duluth Forge log set suits an existing fireplace and offers propane or natural gas operation. For propane-only setups, consider the Duluth Forge 24-inch Split Oak set or the Americangaslogs 18-inch set. Check firebox dimensions and local rules before choosing a ventless model.

Duluth Forge FDI32R Ventless Insert
Best for: Buyers who want a complete ventless fireplace insert with fuel flexibility. This model is rated at 32,000 BTU and is listed to heat up to 1,500 square feet. Its dual-fuel design supports liquid propane or natural gas, and the remote has an LCD screen for turning the burner on and off.
The insert includes nine hand-painted ceramic fiber logs, a mesh screen, and manual flame adjustment. It is a stronger fit than a log-only set when the project calls for an insert rather than an arrangement of logs inside an existing firebox.
Limitation: It is ventless, so confirm that this type of appliance is permitted in your location and appropriate for the room before buying.
Duluth Forge 24-Inch Dual-Fuel Logs
Best for: Homeowners with an existing fireplace who want the option to use propane or natural gas. This ventless 24-inch set is rated at 33,000 BTU and includes eight hand-painted Berkshire Split Oak logs, an iron grate, a U-burner chassis, and embers.
The included remote can turn the burner on or off and switch between manual and thermostat control. Choose this model if fuel flexibility and remote temperature control matter more than getting a complete insert cabinet.
Limitation: This is a log set for an existing fireplace, not a standalone insert. Measure the firebox and verify installation requirements before purchase.
Duluth Forge 24-Inch Propane Split Oak Set
Best for: Buyers who have propane service and want a 24-inch ventless log set. The listed output is 33,000 BTU, with coverage stated up to 1,300 square feet. Its nine ceramic logs have hand-painted bark, split, and charred details, and the burner includes a glowing ember bed.
This set is a straightforward choice when natural-gas operation is not needed. The ember material is included to create a glowing effect, and the product description specifies liquid propane fuel.
Limitation: Unlike the dual-fuel models, this set is listed for propane only. Confirm that the existing firebox can accommodate its dimensions and installation needs.
Americangaslogs 18-Inch Propane Set
Best for: Shoppers who need a compact propane log set and want a remote. The product is listed for propane only, with output up to 36,000 BTU and coverage up to 1,000 square feet. Its stated minimum firebox dimensions are 14 inches high, 20 inches wide, and 13 inches deep.
The package description includes ceramic logs, a remote, receiver, and hardware. Manual flame adjustment is also listed, giving users another way to adjust the flame.
Limitation: It cannot use natural gas, and the listed firebox measurements are minimum dimensions—not a substitute for checking the full installation instructions.
Duluth Forge 18-Inch Dual-Fuel Logs
Best for: Buyers seeking a smaller log set that can run on propane or natural gas. This 18-inch stacked red oak model is rated at 30,000 BTU and lists heating coverage up to 1,000 square feet. Features include a remote, Piezo ignition, and an oxygen depletion sensor described as shutting off the unit if carbon monoxide or low oxygen is detected.
The manufacturer specifies indoor use and installation in a masonry or agency-approved firebox. That makes it a relevant option for an existing approved firebox rather than a new, freestanding insert installation.
Limitation: Some assembly is required, and the firebox requirement makes installation suitability an important check.
Buying Guide: Choosing a Propane Fireplace Insert or Log Set
Do you need an insert or a log set?
An insert is a complete fireplace-style unit, while a log set is designed to sit in a compatible existing firebox. The Duluth Forge FDI32R is the insert option in this selection. The other featured products are log sets, so buyers should confirm that their fireplace and firebox are suitable before ordering.
Should you choose propane-only or dual fuel?
Choose a propane-only model if you intend to use liquid propane and do not need natural-gas operation. Dual-fuel sets offer a choice between propane and natural gas, but the product must be configured and installed for the selected fuel as directed by its instructions. Do not assume a propane-only product can be converted.
How much heat output do you need?
Compare the listed BTU output and coverage with the room and the manufacturer’s guidance. The featured options range from 30,000 to 36,000 BTU, with stated coverage varying by model. These figures are product claims, not a guarantee of heating performance in every home.
What should you check before installation?
Measure the firebox, review the appliance’s installation manual, and check local building and fire requirements. Ventless products do not use an outside duct or chimney, but that does not mean they are allowed in every location or room. Use a qualified professional when required or when fuel connections are involved.
Frequently Asked Questions
Can a propane gas log set go in any fireplace?
No. Check the set’s firebox requirements, dimensions, fuel type, and installation instructions. Some products require a masonry or agency-approved firebox.
Are ventless fireplace inserts the same as vented gas logs?
No. Ventless products are designed to operate without an outside duct or chimney. Vented log sets are intended for fireplaces with a venting path. Follow the specific product instructions and local rules.
Can dual-fuel fireplace logs use propane?
The dual-fuel models listed here are described as compatible with liquid propane and natural gas. Confirm the required setup for your chosen fuel in the manufacturer’s instructions.
How do I choose between an 18-inch and 24-inch log set?
Start with the fireplace’s usable dimensions and the product’s installation requirements. Select a size only if the firebox can accommodate it; do not choose based on log appearance alone.
