Correcting furnace combustion is a job best left to a professional.
One may also ask, where is the flame on a gas water heater? It is located on the outside of the water heater where the gas pipe enters the unit and has have a knob on it. The valve regulates gas flow to the pilot burner beneath the hot water tank. Turn the valve knob to the “Off” position.
People also ask, why is my water heater flame yellow?
Some gas water heaters are equipped with the air shutter, which allows you to adjust the air-gas mixture for proper burning. Too much air will cause the burner flame to lift off the burner ports and burn with the noise. Yellow or orange flames are an indication that a problem has occurred.
How do you know if you have a bad thermocouple?
If you can't get the flame to light at all, and you're sure the gas is on, there's probably an obstruction in the pilot tube. If the flame lights and goes out when you release the gas control knob after holding it in for the recommended 20 to 30 seconds, that's the sign of a thermocouple malfunction.

A proper pilot flame should be blue with a yellow tip and should be strong enough to cover about 1/2 inch at the end of the thermocouple tip.How does a gas water heater work?
A gas water heater works by a law of physics knowns as convection—which defines how heat rises. In the case of a water heater, the cold water enters the tank through a cold water supply tube to force a constant supply of cold water into the tank.How long does it take water heater to reheat?
40 minutesHow do you adjust the flame on a gas water heater?
Pilot adjustment may be necessary for proper main burner ignition of the water heater. The pilot adjustment screw is located on the gas valve, just “above” the pilot tube (See Figure 3). Remove the cap screw and find the actual adjustment screw behind it. Turn the screw in to decrease pilot flame, out to increase.What color flame should a gas heater have?
