The best LP ventless fireplace option depends on whether you want a complete insert, a propane log set, or an electric unit that avoids gas. The Duluth Forge FDI32R and FDF400RT-ZC are dual-fuel inserts that can run on liquid propane or natural gas; the Duluth Forge DLS-L18R-2 and EROMMY set are propane-only log systems. The PuraFlame is electric, so it is an alternative—not an LP ventless fireplace.
| Product | Best suited for | Fuel or power |
|---|---|---|
| Duluth Forge FDI32R | Buyers wanting a dual-fuel insert with remote control | Natural gas or propane |
| Duluth Forge DLS-L18R-2 | Buyers seeking a traditional stacked-oak look | Propane |
| EROMMY 27-Inch Ventless Fireplace Logs | Propane users who want thermostat and child-lock remote features | Propane |
| Duluth Forge FDF400RT-ZC | Buyers who prefer a dual-fuel insert with doors and brick liner | Natural gas or propane |
| PuraFlame Western Electric Insert | Buyers who want an electric alternative without gas logs | Electric |
Duluth Forge FDI32R Dual-Fuel Insert
Best for: Buyers who want the flexibility to use either liquid propane or natural gas. This 32,000-BTU ventless insert is listed to heat spaces up to 1,500 square feet and does not require an outside duct or chimney, according to the product information.
The included remote has an LCD screen and can turn the burner on and off. The unit also has manual flame adjustment, nine hand-painted ceramic-fiber logs, and a mesh screen. Its dual-fuel design makes it a better fit than a propane-only set for households that may need either listed fuel type.
Limitation: This is a gas appliance, not an electric insert. Confirm the selected fuel, installation requirements, and whether vent-free appliances are allowed in your location before buying.
Duluth Forge 18-Inch Propane Oak Log Set
Best for: Buyers who want a traditional stacked-oak appearance and specifically use liquid propane. This is a vent-free gas log set rather than a complete fireplace insert, so compare its form and installation needs with those of a boxed insert before choosing.
The set produces 30,000 BTUs and is listed to heat spaces up to 1,100 square feet. Its seven hand-painted ceramic logs are made from real wood molds, with a stacked red-oak design and realistic charring. The product information describes it as 99.9% vent-free efficient.
Choose this model if a classic oak-log look matters more than dual-fuel flexibility. It is better suited to a propane-only setup than a home that needs a natural-gas option.
Limitation: The listed fuel is liquid propane only. Do not assume it can operate on natural gas or that it is a drop-in replacement for a full insert.
EROMMY 27-Inch Propane Ventless Logs
Best for: Propane users who value remote-control options, including thermostat mode and a child-lock feature. The manufacturer lists this 27-inch log set for LP/propane use only, with a 34,000-BTU vent-free burner and coverage up to 1,200 square feet.
The remote offers manual and thermostat modes, customizable temperature settings, and Fahrenheit/Celsius conversion. The product description also states that the unit shuts off after two hours if no signal is detected for 15 minutes. Its nine hand-painted birch-style logs are made from high-temperature ceramic.
Compared with the Duluth Forge oak set, this is a better match for buyers looking for listed remote functions and a birch-log appearance. Check the exact installation and opening requirements before ordering; the supplied product details do not establish universal fit.
Limitation: It is for propane only. Its remote functions do not change the need to follow the product’s instructions and local requirements.
Duluth Forge FDF400RT-ZC Dual-Fuel Insert
Best for: Buyers seeking a dual-fuel insert with a more enclosed visual design. Like the FDI32R, this 32,000-BTU model is described as compatible with natural gas or liquid propane and as heating up to 1,500 square feet without an outside duct or chimney.
The insert includes a remote with an LCD screen for switching the burner on and off, a standing pilot, and manual flame adjustment. Its six hand-painted ceramic-fiber logs, mesh double doors, and sprayed brick liner distinguish its appearance from the FDI32R’s mesh-screen design and nine-log arrangement.
Choose this model if the doors and brick liner better suit your fireplace style. Both Duluth Forge inserts offer dual-fuel flexibility, so compare their listed design details and confirm the dimensions and installation requirements for your opening.
Limitation: The product information does not give insert dimensions. Measure the intended space and verify fit rather than relying on the model name or appearance.
PuraFlame Western Electric Fireplace Insert
Best for: Buyers considering a fireplace look without an LP gas burner. This product is an electric insert, so it is not a direct substitute for a ventless propane appliance when propane heat is the requirement.
The listed overall dimensions are 35 1/16 inches wide, 26 31/32 inches high, and 8 25/32 inches deep. It offers three flame-intensity settings that can be used with or without heat, a remote, and 750- or 1,500-watt heat settings. The design includes a brick-style interior, glass front trim, and a resin log over an ember bed.
Choose this if electric operation and flame effects matter more than gas fuel. The product description also highlights LED technology and no dust or ash cleaning.
Limitation: It uses electricity rather than propane. The seller advises contacting them if you are unsure whether the unit fits your opening; compare the firebox dimensions with the available space.
Buying Guide: How To Choose An LP Ventless Fireplace
Do you need a complete insert or a log set?
A fireplace insert and a gas log set are different product formats. The Duluth Forge FDI32R and FDF400RT-ZC are presented as fireplace inserts. The Duluth Forge DLS-L18R-2 and EROMMY products are log sets. Before purchasing, identify which format suits the existing fireplace and confirm what the installation instructions require. Do not assume that a log set and an insert are interchangeable.
Should you choose propane-only or dual-fuel?
Choose a propane-only product if liquid propane is the fuel you intend to use and the product’s instructions match your setup. The DLS-L18R-2 and EROMMY set are identified for propane use. Choose a dual-fuel model if you want the listed option of natural gas or liquid propane, as with the two Duluth Forge inserts. Confirm the fuel configuration before installation; do not treat fuel types as interchangeable without manufacturer guidance.
How much heating output should you compare?
Compare both the stated BTU output and the listed coverage area, but treat coverage figures as product claims rather than guarantees for every home. The listed figures range from 30,000 BTUs and up to 1,100 square feet for the Duluth Forge oak log set to 34,000 BTUs and up to 1,200 square feet for the EROMMY set. The Duluth Forge inserts list 32,000 BTUs and up to 1,500 square feet. Room layout and other conditions can affect heating needs.
Which remote features matter?
Remote functions vary. The FDI32R and FDF400RT-ZC list an LCD-screen remote for burner on/off operation and manual flame adjustment. The EROMMY description additionally lists thermostat mode, temperature settings, a child lock, and a stated signal-related shutoff feature. The DLS-L18R-2 product details provided here do not specify a remote, so verify the current listing if remote operation is essential.
What should you check before ordering?
- Measure the fireplace opening and compare it with the product’s dimensions and installation instructions.
- Verify the fuel type and whether the appliance is intended for the planned location.
- Check local rules and applicable safety requirements for vent-free gas appliances before purchase or installation.
- Follow the manufacturer’s instructions and consult a qualified professional when installation requirements are unclear.
- Consider whether the listed appearance—oak, birch, mesh screen, doors, or brick liner—fits your existing fireplace.
Vent-free gas appliances do not use an outside duct or chimney according to the listed descriptions for several products here. That feature does not remove the need to follow the appliance instructions, local codes, and safety guidance. Confirm that a vent-free unit is permitted and appropriate for the intended space before selecting one.
Frequently Asked Questions
What is the best LP ventless fireplace insert in this list?
The Duluth Forge FDI32R is a strong match for buyers seeking a complete dual-fuel insert with a remote and a stated 32,000-BTU output. It supports listed natural-gas or liquid-propane use, so verify the chosen fuel and installation requirements.
Can a natural-gas insert use propane?
Only if the product is specifically listed for both fuels and configured as directed. The two Duluth Forge inserts in this article are described as dual-fuel. The DLS-L18R-2 and EROMMY products are listed for propane only.
Are ventless gas logs the same as a fireplace insert?
No. The products described as log sets are not the same format as the Duluth Forge fireplace inserts. Compare the product type, installation directions, and fireplace opening requirements before ordering.
Does the PuraFlame insert use LP gas?
No. The PuraFlame Western is an electric fireplace insert. It may suit buyers seeking an electric alternative, but it does not meet a requirement for an LP ventless gas appliance.
Do ventless fireplaces need a chimney?
The listed Duluth Forge inserts are described as not requiring an outside duct or chimney. Always check the specific product instructions and local rules; the details can vary by appliance and location.
How do I know whether an insert will fit?
Measure the opening and compare it with the manufacturer’s stated product and firebox dimensions. The PuraFlame listing provides overall and firebox dimensions, while the supplied details for the Duluth Forge inserts do not. Contact the seller or manufacturer if fit remains uncertain.
