chuckconnie Report post Posted January 20, 2015 More often than not, when we start our water heater on gas, it sounds like a mini explosion. Any clue the cause and a fix?Thanks Chuck Share this post Link to post Share on other sites
wolfe10 Report post Posted January 20, 2015 Chuck, Sounds like the mixture (propane to air) is not correct and/or the igniter is not firing as the gas valve is opening. I would start by cleaning the gas jet and burner tube-- a mud dubber nest, or even small spider web can change the mixture. Check the igniter gap at the same time. If you have compressed air, while protecting your eyes, blow into the opening where the burner is located. It is a large U shaped tube-- junk will be blown out the top of the U. After cleaning, if symptoms persist, listen while someone else turns it on-- be sure to stand NEXT TO the water heater not in front of it. Does the igniter start clicking immediately when the gas valve clicks open? Share this post Link to post Share on other sites
dickandlois Report post Posted January 20, 2015 Chuck, After you check the burner tube is clear as Brett suggested. Make sure the ignition contacts are positioned properly! Just do me a favor and stand back from the water heater with the door open--When you have some one turn it on please. Depending on how the gas valve and ignition are working, there can be a sizable flash when the LP lights up !!!! Rich. Share this post Link to post Share on other sites
