Our take on the Duluth Forge Liquid Propane Ventless Gas Fireplace Insert - 26,000 BTU, T-Stat Control - Model# FLF300T

The Duluth Forge FLF300T is a ventless liquid propane fireplace insert rated at 26,000 BTU, enough to heat roughly 1,350 square feet. It drops into a zero-clearance opening or recesses into a wall, and a thermostat knob cycles the burner to hold room temperature. A battery-assisted piezo igniter means it lights without a wall outlet, and an oxygen depletion sensor shuts the gas off if oxygen drops. Against vented inserts and freestanding vent-free heaters, it wins on installation freedom and loses on flame realism and indoor air quality.

Questions and answers

Does this insert need a chimney or vent?
No. It is ventless, so it needs no flue or chimney. It does need clearance to combustibles and a propane supply.
How much space will it heat?
Duluth Forge rates it at 26,000 BTU, enough for about 1,350 square feet. In a cold climate or an open floor plan, treat that as supplemental heat.
Will it work in a power outage?
Yes. The piezo igniter runs on batteries and the burner needs no electricity, so it can heat during an outage.
Can I recess it into a wall?
Yes. It is a zero-clearance insert, so it can go into a framed opening or pair with a face mantel. Follow the clearance instructions exactly.
Is ventless propane safe indoors?
It has an oxygen depletion sensor that shuts the burner off if oxygen falls. Ventless units still add moisture and combustion byproducts, so follow the manual on room size and ventilation.
What do I need to install it?
A propane line or tank, a framed zero-clearance opening or mantel, and the clearances in the manual. A licensed gas installer is the safe route for the hookup.
