Urbana · U33 Series

The traditional one, done modern.

One almost-square window of fire — a clean face with no louvers, on a stainless burner.

I

Clean face, no louvers

In Urbana’s words: “Clean Face - No Louvers.” The glass sits flush in smooth steel — nothing above or below the window but metal.

II

A burner with depth

Urbana’s “3D Stainless Steel Burner,” under your choice of birch or traditional split logs on a crushed-stone bed.

III

One face or two

“Standard or See Through Configurations Available” — the same firebox can open through to a second room.

Quick answers

The three things everyone asks.

Will it fit my wall?

The chase wants a minimum width of 55⅜″ with the Cool Surface System active (70½″ without), on a 5″ × 8″ direct vent. Send us a photo of your wall and we’ll confirm the fit before you spend a dollar.

Can it open to two rooms?

Yes — in Urbana’s words, “Standard or See Through Configurations Available.” The see-through kit turns the same firebox into a window between two rooms.

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.
