What you get

The Duluth Forge DLS-N18R-2 Natural Gas Vent-Free Gas Log Set is a vent-free log set with a 30,000 BTU/h burner.

As a vent-free set it heats the room rather than the chimney, within the room-size and altitude limits in its manual; some local codes restrict vent-free logs.

At full fire it burns about 29 cubic feet of natural gas an hour.

Measure the firebox front width, rear width, depth and height and check them against the minimums in the set's manual before ordering. Vented vs vent-free logs.

Also on the listing: overall dimensions of 13 in (D) x 18 in (W) x 12 in (H), a shipping or unit weight of 11.36 kg and ceramic, metal construction.
