No, it is not dangerous. (Unless you are working with a water heater that is 20+ years old.) In any modern hot water heater, if the pilot light goes out a fail-safe will go off - preventing gas from leaking out. Also, there is a sensor so if there is not enough air-flow or oxygen with the water heater, it will shut off the gas.
Have you turned the control from Pilot to On? Have you increased the temperature setting?
If the pilot light is on, the heater should come on by itself. If the pilot light is off then it has to be lit. If it will not stay on, the thermocouple is bad.
You could have a dangerous vent back flow problem. Please call your utility company about an inspection (mine doesn't charge for this). How old is the water heater?
You don't. If the heater has an electronic spark, then it doesn't have a standing pilot to light. The spark lights the pilot when there is a call for heat, which in turn lights the burners. If the heater is on and the pump is RUNNING, the heater should light automatically when the water temperature is lower than the heat setting.
High winds, pilot generator. Is the heater located next to a wall? Is the heater door closed? Does the heater have a draft hood or what they call a stackless heater? Ken
because its leaking out gas
the pilot light in my fireplace is working but when i turn the switch on (new switch) it wouldn't fire up
== == Yes!
Gas water heater has an orifice for main burner and for pilot light, if not electronic ignition.
Check to see if you pilot light is lit
Most likely your pilot light is out
Yes
