The actual cost to install a gas fireplace may vary depending on your location, the product selected, complexity of the installation process, additional accessories purchased, and other options. 1  Top vented gas fireplace inserts cost $750 to $3,000, and installation adds another $500 to $1,000. The cost of a ventless gas fireplace is $500 to $2,500, and while there are additional installation costs, you may pay extra for finish work (such as a mantle, marble surround, etc.).
Converting existing fireplaces to gas is the least expensive option for homeowners and involves simply inserting gas logs. These nonflammable logs look much like real wood, and come in vented and ventless types. Vented gas logs require a working existing chimney and cost from $300 to $550, according to CostHelper. Ventless gas logs do not need a pipe or chimney and cost from $350 to $600. Installation adds $200 to $350 extra to cover a licensed contractor and a new gas outlet. Another conversion method uses top-vented gas fireplace inserts, which may include fans and thermostats.
