Hazardous chemicals can induce a hot zone, as occupants are in danger of it disrupting their biological processes. For example, if while driving down a highway, an oil tanker gets into a car accident and spills its load on the pavement and surrounding grass areas, those areas affected will be considered hot zones.
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.
Installation and finishing typically add $2,500. Cost saver tip: Switch to a simpler surround and mantle, and get a direct-vent fireplace so you donât need a chimney. Or, opt for a vent-free gas fireplace for $400 or so. Hiring a professional to install a gas line or a connection to a propane tank adds about $1,000.
