Vented gas logs are for a real wood burning fireplace with a working chimney. They burn with the damper open and give the fullest, most realistic wood-fire look. You’ll choose natural gas or propane on the product page; a set built for one fuel cannot be switched later.

Think about the look you want on your hearth, from traditional split oak to pale birch or driftwood over a glowing ember bed. Check whether your gas log set includes a burner or needs one selected on the same page.


How to choose vented gas logs

For realistic bark and char detail, explore Real Fyre’s hand painted styles. For single-sided, see-through or linear layouts, browse Grand Canyon’s wood-cast designs. See-through logs are painted on both sides for a two-sided fireplace. For Fiberglow sets with glowing ceramic fiber logs and battery powered ignition in 18 and 24 inch sizes, explore Napoleon gas logs.

Measure your firebox opening before choosing a size. Most sets come in 18, 24 or 30 inches, with larger options available. Leave room on each side according to the set’s requirements.

Choose match lit controls for no pilot or electronics, a standing pilot that needs no household power, or remote or electronic ignition. For an outdoor fireplace, choose an outdoor-rated set; outdoor burners use stainless steel and match lighting.

If room heat matters more than a full flame, compare vent free gas logs before choosing.

Frequently asked questions

What is the difference between vented and ventless gas logs?

Vented sets need a working chimney and open damper for the fullest, most realistic flame; most heat escapes. Ventless sets need no chimney, use a closed damper, retain heat and have an oxygen sensor. Your fireplace and preference for looks or heat guide your choice.

Do vented gas logs need a working chimney?

Yes. They need a real wood burning fireplace with a chimney that draws. Keep the damper open the whole time the fire runs. If the chimney is blocked or your fireplace has no flue, look at ventless sets instead.

Do vented gas logs give off heat?

Some radiant warmth reaches the room from the flames and glowing logs, but most heat goes up the open chimney. Choose vented for the look of a real fire; consider ventless when heating the room is your main goal.
