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 for a natural gas fireplace can cost anywhere from $300 to $1,200 depending on the availability of natural gas and electricity in the location where you want the fireplace, as well as a number of other factors.ood burning fireplaces tend to be less expensive than natural gas or propane on the low end, but much more expensive on the high end. Most masonry fireplaces cost $5,000 or more due to the labor required to install each individual brick or stone within your home.
