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.
The pilot light from your water heater is the flame that will ignite the fumes from any spilled flammable liquids. If your water heater is NOT a flammable vapor ignition resistance water heater, it must be raised to 18 inches if it is located in the garage where a car would be parked. In some of the cities on the Peninsula and in the Bay Area, you may install a flammable vapor ignition resistance water heater on the ground in a garage.
