How To Remove And Replace A Gas Fireplace Valve

(Last Updated On: October 22, 2013)

We recently turned our gas fireplace on and had an issue with the valve supplying gas. We ran some tests and determined that the valve was stuck in the closed position. The inside of the valve had failed therefore the gas was unable to be supplied into the fireplace area. This replacement on/off gas valve was available online for around $40 dollars so we purchased the valve and installed it ourselves. See below for our step by step procedure on safely removing and replacing a gas fireplace valve.

NOTE: It is highly recommended to have a licensed professional repair your gas fireplace valve. There is no room for error here as if you do not tighten the fittings properly a gas leak can occur and death or injury can result. So, if you are experienced mechanically and have solid DIY know how, then proceed but with extreme caution. Here are some important Gas Fireplace Safety Tips to read for more information.
