The difference between an orange flame and blue flame is the amount of air in the combustion process. SO if the flame is orange it is being starved of oxygen. The gas burns dirty and soot is generated.

Sometimes with an older heater the exhaust venturie becomes plugged and carbon monoxide is released into your home- in this case your heater would make a woof or poping sound when starting up or shutting off. This is a dangerous unsafe situation and professional help is needed.

What you can do is try to make adjustment yourself, if your confident the other situation does not exist. Your water heater should have a little deflector shield on the gas line between valve and burner (typically immediatly after the orfice). Sometimes these will have to be slide front or backwards or twisted. The adjustment of deflector shield must be opened more to make the blue hotter flame to mak eyour heater operate at peak efficiency.

Good Luck

My gas richmond water heater quit working, replaced thermal coupler light pilot good burner lights and goes out


Did you get the thermocouple positioned so the pilot flame just touches the side of the thermocouple sensor? Is the pilot flame blue with a slight orange tip? Did you use an exact replacement part? Not all thermocouples produce the same millivolts needed to keep the gas valve open. If you think all of these items are correct, then the main gas valve is defective.

Burners on tankless Paloma PH-12m-Dn don't burn hot enough to heat the water


Check the flame color when it's on. Blue tips are correct. If the tip is orange or any other color but blue, the air mixture is out of adjustment. Check the owners manual for instructions on making this adjustment

Flame burning too orange


You need to get a Plumber or Appliance Tech to come out immediately and check the fuel to air ratio. You are not burning your fuel at the proper mixture. A blue flame is good, yellow-orange is bad.

Normally this is because the burner area is dirty or the pressure regulator may be set too high/low. The black marks are a sure sign that your ratio is too rich and it's just going to build up more soot and become unhealthy and dangerous.

I have a new Atwood G6A-7 water heater. The pilot lights fine but gas flow, when it turns on, is so strong it will blow the pilot out. Certain times, it sounds and looks like a mini fire ball going


Clean burner tube with proper brush, such as long spring type for bar-b-Q burner tube that are available at most hardware stores, and make sure you have new burner tube aligned properly (straight on) with brass orifice on gas control. Then be sure to adjust air shutter for nice blue flame, with little orange at tip. Do not give so much air that flame roars or jumps off the end of the burner tube. Too many people think more air, less fuel, but actually, when flame roaring and jumping off end of tube, the heat passes through faster and it takes longer to heat the water inside the tank. Like I said, only enough air to have quiet, steady blue flame. If your not giving it enough air, you'll see dark soot on trailer above water heater, which indicates burning too rich, need more air, or perhaps pilot is partially plugged. Pilot flame should also be blue, not yellow/orange. Small air intake hole on side of fitting just before pilot tube can get spider web, or debris in it as well. Use air to blow that out or a piece of wire like a paper-clip to clean inside that hole.

Kenmore Water heater, Model # 153.339462, Pilot lights, burner burns for approx. 10 - 15 minutes then both go out. after which it is more difficult to light the pilot. I need ideas please


Clean combustion parts, clean air intake, get more air to water heater and see if problem continues.
Look at color of burner flame and pilot flame: if flame has yellow-and-orange instead of clear blue flame, then combustion parts need cleaning.

Pilot and burner problems can be caused by bad thermocouple, thermocouple not sitting in flame, weak pilot flame due to dirty tube or low gas pressure, air in gas line, no draft up vent, backdraft coming down vent, dirty combustion parts, clogged air intake, insufficient air, insufficient air quality, hot attic, bad gas control valve, etc.

Open following link for pdf resources, and illustrations for cleaning combustion parts, and some service manuals:

Not heating enough for one full shower


Is this gas or electric heater?

Gas heater, the thermostat might be bad.
You might need to change out gas valve.
Also look in and see if flame is light blue or yellow.
Blue is good.
Yellow flame means you need to clean burner, or replace burner.
Burner should be cleaned each year.
Refer to manual for instructions and parts list.
http://www.whirlpoolwaterheaters.com/support/Manuals.aspx
Also tank might be filled with sediment.
http://waterheatertimer.org/Clean-sediment-out-of-water-heater.html

Electric water heater is different altogether:
Some hot water means upper element is working.
Water heater ECO reset button is good.
Tank is not overheating.
Electricity and circuit breaker are good.
Remaining suspects:
Thermostats are bad, loose wire, shorted wire, lower element burned out, sediment inside tank.

I test instead of guess:
Here is 30 minute troubleshoot overview that will identify problem and show how to repair electric water heater.

G4-7 atwood water heater lights great, heats water but when it cycles the pilot goes out no hot water


Sounds like the burner flame may be too strong (jumping out from burner tube) . Some people think the louder the better, but that is not correct. When burner shuts down like that, it has a tendency to snuff out pilot as well. Adjust your air shutter at burner so that the flame is a nice blue, or with just a hint of orange/yellow at the tip. Whatever setting that keeps the flame solid from burner tube, and not a big gap between tube and flame. Signs of soot (black) up the cover, or side of trailer means it's running too rich, and you've gone too far thus needs more air. Keeping the flame blue but still right out of the burner, actually heats better, is quieter, and should eliminate that pilot getting snuffed out. Pilot should also be a nice blue flame as well. There may be a problem with positioning of the burner tube as well, but doubtful if it has been running well in that position before. Let me know what happens.

Whirlpool Water Heater flame goes out shortly after being lit.


This problem sounds as if gas pressure to the burner is to low, check mnfr's plate on heater for the correct burner manifold pressure, you will need a manometer or a guage that measures inches of water column, set the pressure correctly and the burner should stay lit.
