Wood & Gas Fireplace Installation

Allegiance is more than Chimney Services, we sell and install new fireplaces, stoves & vented gas log sets across Nashville.

Allegiance Chimney Solutions installs gas fireplaces, gas inserts, vented log sets and wood burning appliances across Murfreesboro, Rutherford County and the wider Middle Tennessee market. We are a dealer for Valor and Blaze King, and our certified technicians handle the whole job, from sizing the appliance and running the venting to the final gas connection and the first burn.

Middle Tennessee is not a market where a fireplace carries the heating load. Most winters here run mild, and a gas fireplace earns its place for the sixty or so evenings a year when the house needs a warm room rather than a warmer furnace setting, and for the handful of ice storm days when the power goes out and a sealed combustion gas appliance is the only heat still working.

Insert, Built In or Log Set

Three very different products get called a gas fireplace, and picking the wrong one is the most common and most expensive mistake homeowners make here.

• A gas insert slides into an existing masonry or factory built firebox and seals it. It converts a fireplace you already have into a sealed, efficient heater, and it is the right answer when the masonry is sound and the chimney can take a liner.
• A built in direct vent fireplace is a complete appliance framed into a wall. It does not need an existing chimney at all, which is what makes it the option for additions, basements, primary suites and new construction.
• A vented gas log set drops into an existing open fireplace and burns with the damper open. It produces the look of a wood fire with almost none of the heat output, because most of it goes up the flue. Choose it for appearance, not for warmth.

We walk through this in the home rather than over the phone, because the answer depends on what firebox you already have, where the gas line runs, and whether you want the appliance to heat the room or just look like it does.

Direct Vent, B Vent and Vent Free

Venting is what determines efficiency, indoor air quality and where the appliance can legally go. Direct vent is the standard on nearly everything we install. A sealed glass front separates the firebox from the room, a coaxial pipe pulls combustion air in from outdoors and pushes exhaust back out, and nothing from the fire enters the living space. It can vent through a wall or up through the roof, and it operates during a power outage.

B vent, sometimes called natural vent, draws combustion air from inside the room and exhausts through a vertical flue. It is older technology, it is less efficient because it is constantly pulling conditioned air up the chimney, and it is uncommon on new installations.

Vent free appliances discharge every byproduct of combustion, including water vapor, into the room. They are efficient on paper and we understand the appeal of a firebox that needs no venting at all. They also raise humidity noticeably in a closed house and they are restricted or prohibited in certain rooms and certain jurisdictions. We will tell you honestly whether one is appropriate for your home rather than steering you toward whichever product is easiest to install.

Check out some of our previous work to spark your imagination for your new fire feature:

Gas Fireplaces

Sealed direct vent fireplaces installed into existing masonry openings and into newly framed walls. These are the units that actually heat a room, and most of them run on a wall switch, a remote or a thermostat.

Vented Gas Log Sets

Log sets fitted into open fireplaces for homeowners who want the appearance and the convenience of gas without rebuilding the firebox. The damper stays open while they burn, so plan on ambiance rather than heat.

Wood Freestanding Stoves

Freestanding wood stoves, including Blaze King, set on approved hearth pads with code compliant clearances and a new stainless liner or class A chimney. These are the appliances people choose when outage proof heat matters more than push button convenience.

Wood Fireplace Inserts

Wood inserts that seal an open masonry fireplace and turn it into a controlled, efficient heater. Every insert we install gets a properly sized stainless liner running to the top of the flue, because an insert vented into an oversized masonry flue will not draft correctly.

What an Installation Actually Involves

We start with a paid inspection and a measure. The technician verifies the firebox and flue condition, confirms the gas supply and line size, checks clearances to combustibles, and identifies the venting route. That visit is what makes a real quote possible instead of a guess.

On install day the appliance is set, the venting is assembled and sealed, the gas line is connected and leak tested, and the unit is commissioned. Commissioning is the step that gets skipped by low bidders. It means confirming manifold pressure, checking flame appearance and burn characteristics, verifying that the safety controls shut the appliance down when they should, and confirming the venting is drafting under real operating conditions.

Gas work is permitted work. We handle the permitting and inspections required in your jurisdiction and leave you the documentation, which matters both for your insurance and for the appliance warranty.

What Ongoing Service and Repairs Run

A gas fireplace is a gas appliance, not a decoration, and it needs annual attention the same way a furnace does. Burners collect dust, pilot assemblies drift out of adjustment, glass gaskets compress, and the safety controls that shut the unit down need to be verified rather than assumed. Here is what the common items cost so you can budget for them.

Service	Typical range
Annual gas fireplace maintenance	$250 to $400
Diagnostic service call	$250 to $400
Thermocouple or thermopile replacement	$100 to $350
Glass panel replacement	$500 to $1,200
Multi component repair	$750 to $1,200

Installation itself is quoted per project, because the appliance, the venting route and the condition of the existing firebox drive the number far more than labor does. We give you that figure in writing after we have seen the space, and there is no charge for the estimate.

Choosing an Appliance for a Mild Winter Market

Rutherford County winters are short and inconsistent. A week in the thirties gives way to a fifty degree afternoon, and the appliance that makes sense here is one you can run for an evening and shut off, not one that has to be fed and tended all season.

That argues for direct vent gas in most homes: instant on, thermostat capable, no fuel to store, and functional when the grid is down during the ice storms that are Middle Tennessee’s real winter hazard. It argues against oversizing. A firebox rated to heat a large open plan will overheat a typical den here within twenty minutes, and you will end up running it at low output where the flame picture looks worst. Sizing to the actual room is most of what makes an installation feel right afterward.

We serve Murfreesboro and Rutherford County first, and we work regularly in Nashville, Franklin, Brentwood, Spring Hill, Lebanon, Mt. Juliet and Hendersonville.
