how much do gas fireplaces/cost
Costs to convert wood fireplace to gas. Installing a gas line and either vented or vent-free gas logs will cost from $500 to $2,500. (Note that the cost of installing vent-free gas logs is often about $200 more than the cost for vented.) Gas inserts cost $2,000 to $5,500. Expect to pay more for fireplace installation if workers are challenged to get the gas line to your fireplace.
