The Enviro RZ41 gas fireplace in a black studio void — flames rising from beneath its split log set, ember bed glowing across the full width

Fire the way a campfire makes it.

“Fire-Under-Log Technology” — the flames rise from beneath the logs, the way real wood burns.

I

Under, not around

“Fire-Under-Log Technology” — three burners feed flame up through the split logs, so the fire looks lit, not staged.

II

A bed that glows

“Ember Bed Lighting” across the full 41-inch width — the coals keep the show after the flames settle.

III

Modern manners

A “Modern Surround Accent,” the “Cool Surface system,” and a “Run-Quiet Fan System” — classic fire, current engineering.

Quick answers

The three things everyone asks.

Do I need a chimney?

No. The RZ41 is direct vent — a 5″ exhaust and 8″ intake run out a wall or up through the roof. No masonry, no liner, no sweeping.

What makes it different from a log fireplace?

The burners sit UNDER the log set — “Fire-Under-Log Technology” — so flame rises between the splits the way a real fire burns, over a lit ember bed.

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.
