Ulcers most commonly occur on the inside of the mouth but may also occur on the tongue and lips, or in association with more generalized conditions, such as cancer. Allergic reactions to food and other substances may cause inflammation, swelling, and development of mouth white patches.
Part 3 Relighting the Pilot Light. 1. Turn the gas valve to the Pilot setting and push down on it. Doing this starts the flow of gas into the tube that supplies the pilot light. If your water heaterâs gas valve does not push down, look for a red control button near the valve. Hold this button down.
Gas water heaters also have a Vacation setting, which keeps the pilot light on but doesn't heat the water, so you save money on your gas bill when you aren't at home. Turn the gas water heater temperature down to Vacation before you leave, and turn it back up to normal heat when you get back.f you play with different heat settings, you can find a water heat setting on your gas water heater that works for all your needs. If you turn it down too low and you have a dish washer, it may have trouble cleaning the dishes properly because the water isn't hot enough.
