Converting a gas fireplace to wood burning is possible but requires removing the gas insert and installing a wood-burning stove or firebox—a job that usually needs a licensed contractor because it involves disconnecting gas lines and ensuring the chimney is safe for wood fires.

The conversion itself is straightforward in concept: you remove the gas logs and burner assembly, install a wood-burning insert or stove in the same opening, and cap off the gas line. The real work is making sure your chimney can handle wood smoke safely. A gas fireplace produces cooler exhaust that doesn't rise as fast as wood smoke does, so your chimney may need modifications—usually a liner—to work properly with wood. You'll also need to have the chimney inspected and cleaned by a professional before you burn anything.

The cost varies widely depending on whether you're installing a straightforward wood-burning insert (which fits inside your existing fireplace opening) or a full stove, and whether your chimney needs a liner. A basic insert runs $1,500 to $3,500 installed; a stove with chimney work can reach $4,000 to $6,000 or more. Gas line capping is usually under $200 if a plumber does it, but many contractors include it in their quote.

Key Takeaways

  • Your chimney must be inspected and usually lined before you burn wood, because gas fireplaces produce cooler exhaust than wood does and your existing chimney may not draft properly.
  • You'll need a licensed contractor to disconnect the gas line safely and install the wood-burning insert or stove, not a DIY job.
  • A wood-burning insert fits inside your existing fireplace opening and costs less than a full stove, but both require professional installation.
  • Your homeowner's insurance may require notification of the conversion, and some jurisdictions have rules about wood-burning appliances in residential areas.

Why your chimney needs inspection before conversion

Gas fireplaces are designed to work with a chimney that handles cooler, slower-moving exhaust. Wood fires burn hotter and produce smoke that rises faster and carries more moisture. If your chimney was sized and built for gas, it may not draft properly with wood—meaning smoke could back up into your home instead of going up and out.

A chimney professional (often called a sweep or inspector) will examine the interior with a camera, check for cracks, blockages, and creosote buildup, and measure the flue size. They'll tell you whether the chimney is safe to use as-is or whether it needs a stainless steel liner—a metal tube that runs the full length of the chimney to may support proper draft and contain any damage. A liner typically costs $800 to $2,000 depending on chimney height and complexity.

This inspection is not optional. A chimney fire in an unlined or improperly sized flue can damage the structure and create a fire hazard. Most insurance companies and local building departments require a professional inspection report before you convert.

Choosing between a wood-burning insert and a stove

A wood-burning insert is a metal box that slides into your existing fireplace opening like a drawer. It has its own firebox, grate, and damper, and it vents through your existing chimney. Inserts are popular for conversions because they use the space you already have and don't require major structural changes. They're also more efficient than an open fireplace—they radiate heat into the room rather than letting it escape up the chimney.

A wood-burning stove is a standalone unit that sits in front of your fireplace or in another location in the room. It requires its own venting through the chimney (or through a wall if you're installing a new chimney). Stoves are often more efficient and can heat larger spaces, but they take up floor space and require more installation work if you're not using your existing fireplace opening.

For a gas-to-wood conversion, an insert is usually the simpler choice because it fits in the space your gas fireplace already occupies. A stove makes sense if you want to move the heating appliance to a different spot or if your fireplace opening is too small or oddly shaped for an insert.

What happens to your gas line

The gas line that fed your fireplace must be disconnected and capped by a licensed plumber or gas technician. You cannot straightforward leave it in place or cap it yourself—gas lines are under pressure and improper work can create a leak or safety hazard.

The contractor will shut off the gas at the main valve, disconnect the line from the fireplace, and cap the end with a fitting that meets local code. Some contractors will remove the entire line if it doesn't serve anything else; others will cap it in place. Either way, the gas company may need to verify the work, depending on your jurisdiction. This step usually takes a few hours and costs $150 to $300 on its own, though many fireplace installers include it in their overall quote.

Building codes and permits for wood-burning conversions

Most jurisdictions require a permit before you install a wood-burning appliance, and the contractor should handle this. The permit ensures the installation meets local building codes—rules about clearance to combustible materials (usually 12 to 18 inches from the stove or insert to walls or furniture), chimney height relative to the roof, and venting requirements.

Some areas also have air quality rules that limit wood-burning appliances or require EPA-certified stoves, which burn more efficiently and produce less smoke. Check with your local building department or code office before you start—they can tell you whether conversion is allowed in your area and what the rules are.

A final inspection by the building department is standard after installation. The inspector checks that the stove or insert is properly installed, the chimney is safe, and clearances are correct. This inspection is your protection: it confirms the work was done safely.

Insurance and disclosure requirements

Notify your homeowner's insurance company about the conversion. Some insurers require notification before you make the change; others just need to know afterward. A few may adjust your premium slightly because wood-burning appliances are considered a higher fire risk than gas, though the difference is usually small—$20 to $50 per year, if any.

Your insurance company may ask for proof of professional installation and a chimney inspection report. Providing these documents protects you: if a fire occurs and the company later discovers you installed the stove without a permit or inspection, they could deny a claim. Being transparent upfront avoids that risk.

Ongoing maintenance for wood-burning fireplaces

Wood-burning appliances require more regular maintenance than gas fireplaces. You'll need to have the chimney professionally cleaned and inspected once a year, usually in the fall before the heating season. Creosote—a flammable residue from wood smoke—builds up inside the chimney, and cleaning removes it to prevent chimney fires.

You'll also need to clean the insert or stove's glass door and ash pan regularly, and inspect the gaskets (seals) around the door to make sure they're still tight. These are straightforward tasks, but they're part of owning a wood-burning appliance. Budget $150 to $300 annually for professional chimney cleaning and inspection.

Frequently Asked Questions

Can I install a wood-burning insert myself?

No. The gas line disconnection must be done by a licensed plumber or gas technician, and the chimney work requires a professional. Most jurisdictions also require a permit and final inspection, which means a contractor must do the work. Attempting this yourself could result in a gas leak, improper venting, or code violations that void your insurance.

What if my chimney is too damaged to use?

If the inspection reveals cracks, severe deterioration, or a flue that's too small, you have two options: install a liner (the most common solution, usually $800 to $2,000), or have a new chimney built. A new chimney is expensive and usually only done if the existing one is beyond repair. Your inspector will recommend the right solution for your situation.

Will a wood-burning fireplace heat my whole house?

A wood-burning insert or stove can heat the room it's in and some adjacent spaces, but it won't heat a whole house efficiently. If you want whole-house heating, you'd need a central wood stove or a wood-burning furnace, which are different installations. For zone heating (warming the main living area), a fireplace insert works well.

How much does wood cost compared to gas?

Wood costs vary by region and quality, but a cord of seasoned firewood typically runs $150 to $300. A cord heats an average home for about two to three weeks during winter, depending on how much you use the fireplace and how cold it gets. Gas costs vary too, so the comparison depends on your local prices. Wood requires more work (splitting, stacking, storing) but is often cheaper per BTU.

Can I convert back to gas if I change my mind?

Yes, but it's expensive. You'd need to remove the wood-burning insert or stove, have the chimney inspected again, and have a new gas insert installed with a new gas line run from the main. This typically costs $2,000 to $4,000. It's worth thinking through whether you really want wood heat before you convert.
