Ventless Gas Logs Installation in New Braunfels, TX

For the heat. Because nothing goes up a flue, a vent-free set keeps nearly all of its warmth in the room — it's the efficient supplemental-heat choice, and it needs no working chimney. In a purpose-built vent-free firebox the damper stays closed; dropped into a masonry wood-burning fireplace, the set's listing and local code require a damper clamp holding the damper at a fixed minimum-open position, not fully shut. The trade is the flame (shorter and less wood-like than a vented set) plus strict safety rules: a mandatory oxygen-depletion sensor, BTU caps, room sizing, and outright bans in some rooms and jurisdictions. If looks matter more than warmth, vented is the other direction.

Not always — and this is the big legal difference from a vented set, which is fine almost anywhere there's a sound chimney. Vent-free units are banned outright in some jurisdictions and restricted in others, and the manufacturing standard (ANSI Z21.11.2) caps them at 40,000 BTU/hr. They're prohibited in bedrooms and bathrooms unless the unit is under 10,000 and 6,000 BTU/hr respectively. We confirm your local code and the specific room before you buy, because a vented set may be your only legal option.

Every U.S. unit must have an oxygen depletion sensor (ODS) that shuts off gas if room oxygen drops toward 18% — that sensor is the entire reason a vent-free set can run with the flue closed. They're rated as supplemental heat only, the room needs adequate combustion air (often a window cracked an inch), and you should run a CO alarm in the same room. They also dump roughly one gallon of water vapor per 100,000 BTU into the air, so humidity and window condensation are real trade-offs a vented set doesn't have.

Vented logs send 70-80% of their heat up the flue along with combustion gases. Vent-free logs keep nearly all of it (close to 99% efficient) because nothing goes up the chimney. The trade-off is that all moisture and combustion byproducts stay in the room, which is exactly why BTU sizing to room volume — and the ODS — matter so much on a vent-free set.

Gas line connections should be made by a licensed gas fitter, and most jurisdictions require a permit. A bad connection risks a leak or CO; many areas also won't let you tie a vent-free set into a wood-burning firebox without a working damper clamp. Final cost depends on whether a gas line already runs to the firebox, the log set size, and any clamp or sensor work.

Yes. A tech should verify the ODS trips correctly, clear dust and lint from the burner ports (a clogged port is the main cause of sooting and a faint odor), and check gas pressure. Spiders nesting in the burner over summer are a common reason the flame pattern goes wrong the first cold night.

That's the classic limestone-corridor leak. Water enters at a crown crack, a failed flashing seal, or the porous brick face and travels along framing before it shows up as a stain — often a room away from the entry point. We run a moisture meter and a controlled water test to find the actual source, because sealing the stain instead of the source just moves the problem.

Yes, and it has to be done with the right product. Old lime-mortar limestone must breathe; we use a vapor-permeable siloxane repellent that beads water on the surface while letting moisture vapor escape. A cheap film-forming sealer traps water inside the stone and causes spalling — exactly what you're trying to prevent.

A calibrated moisture meter maps where the masonry is wet, and a controlled, isolated water test confirms the entry point — crown, flashing, or brick face — one variable at a time. You get photos of the trace and the source. In New Braunfels, where leaks travel through porous stone, this is the only way to fix it once.

Trace and repair in the dry stretch — late winter or early summer — ahead of the spring and fall storms. Waterproofing sealer and reflashing only cure correctly on dry masonry, so fixing the leak before storm season is both more durable and more effective.
