Our take on the Duluth Forge DFS-300LR-3AS, Vent Free Fireplace System, Fireplace: FLF300R and Mantel: CM300-3-AS, Apple Spice

The Duluth Forge DFS-300LR-3AS is a vent-free propane fireplace system that pairs the FLF300R firebox with the CM300-3-AS mantel in an Apple Spice furniture-grade finish. It puts out 26,000 BTU and is rated to heat up to 1,350 square feet, with a remote thermostatic control, battery-assisted piezo ignition and an oxygen depletion sensor that shuts the unit off automatically. It suits homeowners who want a furniture-style focal point without a chimney or vent run. Against built-in vented fireplaces it installs far more simply, but it runs on propane and needs clearance and ventilation guidance followed, and it lacks the flame realism and logs of higher-end vented units.

Questions and answers

How much space does it heat?
It is rated at 26,000 BTU and up to 1,350 square feet. That suits a large room or open plan area as supplemental heat, not a whole house.
Does it need a vent or chimney?
No. It is a vent-free unit, so it runs without a flue. Follow the clearance and fresh-air guidance in the manual, and check local codes for vent-free appliances.
What fuel does it use?
Propane. The system is set up for propane, so you need a supply and the correct regulator and connection.
How does the remote work?
The remote is thermostatic, so it cycles the burner to hold a set temperature rather than only turning it on and off.
What is included in the system?
The package combines the FLF300R firebox with the CM300-3-AS mantel in Apple Spice. Logs, burner and controls come with the firebox.
Is it safe to leave running?
It has an oxygen depletion sensor that shuts the burner off automatically if oxygen levels fall. Keep clearances and ventilation rules as stated in the manual.
  • No vent or chimney required
  • Cons
    • Propane only, so it needs a fuel supply
    • Vent-free operation adds indoor moisture and needs clearance rules followed
    • Flame realism is below vented gas fireplaces
    • Mantel assembly adds setup time
