Napoleon gas logs in this collection are Napoleon’s Fiberglow vented gas log sets: the Fiberglow 18 and the Fiberglow 24. These sets turn an old, inefficient wood burning fireplace into a mess-free gas fire with a real flame and glowing embers, without remodeling. These Napoleon gas fireplace logs are decorative, made for the look of a log fire. Start by checking your fireplace opening to choose the size.


What comes with Napoleon gas logs?

Each vented gas log set pairs a burner with five realistic Phazer ceramic fiber logs. Napoleon calls this the Fiberglow series, and it holds two Napoleon gas log sets. Your Napoleon log set includes a cast iron grate, cast iron andirons, lava rocks and charcoal embers for a natural appearance. Compare vented sets from every brand or browse all gas fireplace logs.

Check the size and your fireplace

The Fiberglow 18 needs an opening at least 22 inches wide, 18 inches tall and 14 inches deep. The Fiberglow 24 needs 28 inches wide, 20 inches tall and 14 inches deep.

Your fireplace must be noncombustible, such as masonry, with a working chimney. Clean the chimney first. The included damper stop keeps the damper partly open to vent exhaust. Keep glass doors fully open during use. A qualified technician must connect the gas line following local codes.

For room heat, consider Napoleon fireplace inserts. For a new wall or full build, explore Napoleon gas fireplaces.

Light the fire and choose your options

The electronic ignition system runs on four AA batteries, so there is no house wiring. The pilot lights only when you turn the fire on with the flip of a switch. Each product page offers an optional on/off remote control and D cell battery pack. Both sets come ready for natural gas, with a propane conversion kit offered.

Frequently asked questions

Do gas logs need to be vented?

These do. Both Fiberglow sets burn in an open fireplace and send exhaust up the existing chimney. The chimney must work, and the damper stays locked partly open with the included damper stop. Vent free sets are a different kind.

What size Napoleon gas log set do I need?

Measure your fireplace opening. The Fiberglow 18 needs at least 22 inches wide, 18 inches tall and 14 inches deep. The Fiberglow 24 needs at least 28 inches wide, 20 inches tall and 14 inches deep. Call us and we will talk it through.

Do vented gas logs give off heat?

Not much you should count on. Napoleon gas logs are rated as decorative appliances, made for the look of a real fire with no wood to haul. If you want the fireplace to heat the room, a sealed Napoleon fireplace insert is the better choice.

Do Napoleon gas logs work in a power outage?

Yes. The electronic ignition runs on four AA batteries. Napoleon’s manual says the gas system needs no house power, so the fire still lights and runs when the power is out. Keep fresh batteries in the holder behind the logs before storm season.
