This is a full-size vent-free gas fireplace insert from Duluth Forge's 400 Series. It runs on natural gas or liquid propane and puts out 32,000 BTU, enough for roughly 1,500 sq. ft. Zero-clearance approval lets it be framed tight against walls or recessed flush, and a dual burner with a sprayed brick liner and screen doors gives a realistic fire. A remote and an Oxygen Depletion Sensor shut-off come standard. Against vented inserts it needs no chimney or flue, which widens where it can go, but it releases moisture and combustion byproducts into the room and depends on the ODS for safety.

This is a full-size, vent-free, zero clearance gas fireplace insert from the Duluth Forge 400 Series. It is zero clearance approved, so it can be framed in without air gaps or spacing on the sides and top. It can be paired with a face mantel or recessed directly into a wall.
The insert has screen doors, a dual burner that produces generous flames, and a sprayed brick liner. It runs on natural gas or liquid propane and puts out 32,000 BTU of heat, enough to heat up to 1,500 sq. ft. of living space.
Battery-assisted piezo ignition starts the fireplace, and an included remote control operates it. An Oxygen Depletion Sensor shuts the unit off automatically for safety. It is PFS certified and made in the United States.
