I have a Richmond model # 6G50-36PF. The pilot light will light and the burner start for a few seconds and then goes out. Also, the pilot flame has some yellow to it?

Check the following:

See if your heater has a pilot gas adjustment valve. It should be on the gas control valve somewhere. Not all heaters have these. It will be a screw on the valve that can be turned.

Make sure the thermocouple sensing bulb is squarely in the pilot flame and also check that the fitting where the other end of the thermocouple connects to the main gas valve is tight.

Check the pilot gas orifice (where the pilot gas comes out) for carbon build up - you may need to remove the pilot gas line and thermocouple assembly to get to this. This problem is pretty common.

Check the gas pressure to the heater. Run the hot water in the dwelling until the hot water heater starts. Check the flame on the main burner and see what color it is - it should be blue with possibly some yellow-tipped flames. If not, there could be a problem with the gas pressure at the heater or venting. If the heater has a gas pressure regulator, it may be out of adjustment or defective.

Finally, and this isn't very common, the pilot light can be extinguished if there is a draft problem, usually associated with an issue with the flue pipe venting system for the heater or another nearby gas consuming appliance.

Do you have a natural gas or propane water heater. You could possibly have a dirty valve which stops the flow of the gas. Has there been a change with the environment of the water heater. Check for the draft and back blow of the available air. If the water heater is over 6 years old maybe it is time to replace the unit. Good Luck
