The Enviro C72 linear gas fireplace in a black studio void — a wide low ribbon of flame over its fluted liner, recessed in a seamless black wall

The longest line Enviro draws.

Seventy inches of continuous flame — the linear for the wall everyone will ask about.

I

A true ribbon

70″ w × 11⅜″ h of glass — more than six times as wide as it is tall. “Linear design for a striking effect,” in Enviro’s words.

II

Dress it your way

“Customizable with choice of liner and burner media kits” — black glass, driftwood, river rock, or a halogen-lit crystal bed behind the one long flame line.

III

Guarded, invisibly

“Clear View Safety Screen included” — the glass is guarded without a cage over the fire.

Quick answers

The three things everyone asks.

Do I need a chimney?

No. The C72 is direct vent — a 5″ exhaust and 8″ intake run out a wall or up through the roof. No masonry, no liner, no sweeping.

How big is the opening it needs?

The maker’s listed install envelope is 83″ w × 84″ h × 20″ d — and their own footnote says to consult the manual for detailed dimensions and clearances. Send us a photo of your wall and we’ll confirm the fit before you spend a dollar.

What’s the upkeep?

No wood to haul, no ash to sweep. Like any gas fireplace it wants an annual service — that’s our trade, and the crew that installs it does it.

What it costs

Priced to your home — not from a chart.

Every wall is different — framing, venting, gas line — so your price is real, not a guess.
