This is the heart of our floor: sealed, built-in gas fireplaces that go into a wall and become the thing the room is arranged around. Every unit here is direct vent, which means it draws combustion air from outside and exhausts outside, uses none of your room air, and can go almost anywhere with a wall or roof run rather than a chimney.

Linear or traditional?

This is the first fork. Linear units are wide and low, with a long ribbon of flame, and they suit contemporary rooms and feature walls. Traditional units are taller and squarer with a log set and glowing embers, and they read as a fireplace in the way most people picture one. Both throw real heat; the choice is aesthetic.

Formats worth knowing about

Beyond single-sided, we carry see-through units that turn a wall between two rooms into a shared feature, corner units, bay and peninsula formats, and indoor-outdoor fireplaces that open to a patio on the far side. If a shape seems impossible, ask, because it often is not.

Sizing it

Oversizing is the most common mistake we correct. The units here run from about 16,000 BTU up past 60,000, and a large linear in a small sealed room will drive you out of it. Room size sets the range; our best gas fireplaces guide walks through choosing, and the venting guide explains why placement is more flexible than people expect.

Converting an existing wood fireplace instead? Start with inserts. Every fireplace here is installed by TSSA-certified technicians; see our installation service.

Frequently asked questions

A built-in gas fireplace is framed into a wall as a new installation. An insert is a sealed gas unit sized to slide into an existing masonry or factory-built wood firebox, reusing the opening and venting up the old chimney with new liners.

No. Direct vent fireplaces vent horizontally through an outside wall or vertically through the roof with their own pipe. A chimney only matters when an insert reuses one.

Roughly speaking, a room under 300 square feet suits a compact unit around 18,000 BTU, while larger open spaces take 30,000 and up. Oversizing is the most common mistake, so size to the room rather than to the wall.

Often yes, with the right clearances and usually a mantel or heat management to deflect rising heat. Some units, such as the Marquis Enclave, are rated for zero clearance to a TV above. Our TV above a fireplace guide covers the details.
