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.
I assume vacation keeps the water heater from firing but also keeps the pilot lit, that would be your best bet. It would also be perfectly acceptable to just shut the gas off. There's should be a nearby valve. When you get back just follow the instructions printed on the tank for relighting the pilot.
