Proper gas combustion and the burner flame. The main indicators of the proper gas combustion are the stable blue flame or blue flame with the yellow inner cones (see the picture). It is also OK to see the tip of the flame with a slightly yellow color.
Where does the gas burner go in a water heater?
Every gas-powered and tank-type water heater uses the gas burner located in the combustion chamber to heat water, pilot light or electrode to light the fire, and a gas control valve to deliver natural gas or propane. During the burning process, exhaust gases are vented out, either naturally (convection) or forced (electric blower).
What should I do if my water heater flame is unstable?
Check out the gas valve and if there is a problem do not try to fix it, get a new one.
