I have a 2018 Jayco 174BH I’ve had this for about five years and never used the water heater. I just do winterize my camper and decided I want to try out the water heater and make sure it worked. I filled it up with water, but I can’t get the gas flowing to the heater and get it lit. Any suggestions on what the problem may be, is there a cut off valve specifically for the water heater?
