Brandon K Gold Hill , OR May 09, 2017 Two front gas lines cracked at the valve fittings causing a dangerous situation Relpaced both sets of gas lines/burners. They came with Natural gas orafaces preinstalled, so I backed them out with a wrench and reused my LP orafaces instead. Worked like a dream should. Orafaces were snug, taking out and putting in, but they are coated with some sort of pipe sealer. Maybe took 30 minutes to remove, swap orafaces, then replace the new parts. Works perfectly! 6 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 30-60 minutes
