Fireplace Services

Installing a gas fireplace is where good craftsmanship is invisible and bad craftsmanship is permanent. The unit you see is the easy part; the venting geometry, the gas-train sizing, the framing clearances, and the termination placement are what decide whether you get twenty quiet years of clean heat or a callback every winter. Texas Chimney Experts installs gas fireplaces and direct-vent inserts as a national specialty, and we hold the same engineering discipline whether the job is a builder-grade insert or a wide linear ribbon-burner meant to anchor a room.

The work begins on paper, with a load-and-venting plan, before a tool comes out. Direct-vent and sealed-combustion units are made or broken by the vent run — every elbow, every foot of rise, every inch of horizontal travel shifts the restrictor-plate setting and the draft. We size the coaxial or co-linear pipe to the install manual's vent table, set the flue restrictor to the elevation and run length, and select a termination — flush, snorkel, or high-wind hood — that won't nuisance-trip in a gusty location. Engineering this correctly up front is why our installs burn clean from the first light instead of being "tuned" across three seasons.

The gas side is sized and tested, never improvised. We match the flex connector and CSST to the appliance BTU load, fit the code-required sediment trap ahead of the shutoff, add the bonding clamp on corrugated stainless tubing, and manometer-pressure-test the entire drop before flame is ever introduced. An insert dropping into an existing masonry firebox gets a dedicated, correctly-sized liner run from the appliance collar to the cap — a true positive connection — rather than being vented into an open flue that condenses and back-drafts. That one decision is the most common line between a properly engineered install and a cheap one.

Framing and finish are held to the same measured standard. Zero-clearance and ventless fireboxes are framed to the manufacturer's combustible clearances exactly — never shaved — and the hearth extension and surround meet code projection. We seal the glass front and its barrier gasket so the unit holds its negative-pressure draft, fit the surround and louvers cleanly, and install the ASTM F2972 barrier screen wherever the listing requires it. Commissioning closes the job: manometer-verified inlet and manifold pressure, high-low flame-height calibration set, blower and snap-disc run, and an ambient CO check taken during operation.

The range we install covers it all — direct-vent sealed inserts, vent-free fireboxes with ODS-protected log sets, see-through and two-sided units for room dividers, freestanding direct-vent gas stoves, and linear contemporary fireplaces with glass or fire-glass media. The controls homeowners actually ask for are handled too: thermostatic remote and receiver kits, millivolt wall thermostats, smart Wi-Fi modules, and battery-backup packs so the unit still lights through an outage.

What a documented installer delivers isn't just the appliance set in place — it's the verified record that it was sized, vented, gassed, and commissioned by someone who reads the manual as the floor, not the suggestion. We document the venting plan and the commissioning readings, leave the install clean, and stand behind the numbers. A gas fireplace should be the warmest, quietest, most reliable thing in the room — and provably so.
