What you get

The Real Fyre G18 30-Inch Natural Gas Vent-Free Gas Log Set is a vent-free log set sized for a 30-inch firebox with a 38,000 BTU/h burner.

Vent-free logs run with the damper closed as their manual directs, so their heat and combustion products stay in the room; the manual sets a minimum room size and an oxygen-depletion sensor shuts them off if oxygen drops.

At full fire it burns about 37 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 14 in (D) x 30 in (W) x 18 in (H), a shipping or unit weight of 1.6 ounces and ceramic construction.

The figures, from the maker

Each figure is the maker's or the listing's own, with its source marked. A figure the maker doesn't give is shown as not stated.
