Lyon – 4 Sided See Through Gas Fireplace – Full 360° View

by Sierra Flame

The Lyon 48” brings the see-through linear gas fireplace a wonderful new look! With no screens, safe-to-touch glass, and an incredibly mesmerizing flame, you’ll love the Lyon in any space.

Connect any room in your home and create natural flow with the Lyon’s elegant four-sided design. All of the following is completely built into the fireplace for a sleek and simplified experience:

No Gaps
No need to create ventilation crowns. This fireplace eliminates the top gap usually required in other designs.

No Intake or Exhaust Louvres
The wall remains clean and uninterrupted—no intake or exhaust vents needed to break the visual flow.

No Heat Dump
You won’t need vents behind the wall to manage heat — it's self-contained.

Combustible Friendly
Finish your fireplace wall with standard drywall or wood—no metal studs or cement board necessary.

Clear View Technology:
Double wall glass eliminates the need for safety screens while keeping the view completely open.

Warm Glass System:
Lowers surface temperatures below 172°F, staying safe to the touch while still warming the room.

Easy Clean:
No technician required—remove the glass effortlessly for at-home maintenance and cleaning.
