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.
On my water heater, I could light the pilot and the water heater would burn for 20 minutes or so and shut off. The fix included routing the flue straight through the roof and opening floor to allow more air into the water heater compartment.Another possible culprit may be water-heater vent height above the roof.
