Gas fireplaces come in a wide variety of styles. There are direct-vented, vented, and ventless types, as well as corner models. A direct-vented unit is vented through a masonry chimney or metal chimney, while a ventless model is vented through the wall. In general, direct vent units are used in custom installations, while ventless models are used in prefab fireplaces. 

The cost of a gas fireplace can vary dramatically depending on the type of unit you choose, the location of the unit, and the type of venting required. For example, installing a direct-vented unit may require a new gas line and chimney. Depending on the complexity of the project, the cost may be a few hundred dollars to a few thousand dollars. If the project involves venting through the wall, it may cost anywhere from $200 to $1,200 to modify the existing chimney. 

Installation of a gas fireplace may be done by a homeowner or professional contractor. For a custom installation, the cost may be as much as $500 to $3,000. For a prefab unit, the cost is usually less. In some cases, the installation may only involve connecting the unit to a gas line. In other cases, it may involve constructing a hearth and surround. A mantel and refractory panels may be required. 

Gas fireplaces can be a good choice for those who want to reduce their heating bills. They are clean-burning and require less maintenance than a wood-burning fireplaces. However, they can still cause some health problems, so they are best installed professionally. They also require yearly inspections. During these inspections, an inspector will check for damage to the firebox, venting system, and other problems. 

Depending on the location, the cost of installing a gas fireplace may be much less than the cost of installing a wood-burning fireplace. However, gas fireplaces can be more expensive to operate than wood, so you may want to consider another fuel source. If you have to run an extension line, you will also have to pay for that, as well as the labor cost to build out the area around the fireplace. 

For a direct-vented unit, the cost of installation can be as much as $700 to $5,000 for labor and materials. However, the price can be even more when you add the cost of a new chimney or other venting requirements. Adding additional gas lines can be anywhere from $10 to $20 per linear foot. If the project involves installing a gas line, you will also have to pay for a permit. 

If you are installing a gas fireplace in your home, you will also need to pay for regular inspections. These inspections can be as little as $50 or as much as $150 per visit. If the fireplace is in poor condition, a professional can tell you whether or not the system needs to be replaced. If the unit is in good condition, the cost of a replacement will range from $1,000 to $3,500.
