The only adjustment possible on the burners of modern water heaters is a primary air shutter at the beginning of the burner which regulates the amount of air added to the gas before it burns, but that is not adjustable on most units. Could be a piece of dust or trash got sucked up in the burner - try taking the burner assembly apart and cleaning it.

I just had my furnace cleaned it is a gas rheem. The service guy said it was overheated because of a#3 tube he said the furnace heat exchange is black. What can be do regarding this


I presume you're talking about a gas furnace, even tho the title says Rheem gas water heater. Either way, it works the same for both.

Any black coloring on the heat exchanger is *not* from overheating. Black is from a sooty flame caused by a mis-adjusted burner. (In fact, a sooty flame is less hot). There is an adjustable "air intake plate" for air to enter the burner where the gas enters the burner. A proper flame is made by adjusting this air opening so the proper gas/air mixture feeds into the burner. If the air vent is closed too much it produces a sooty flame.
The age of the furnace is the most important aspect, and that helpful to determine a likely condition of the heat exchanger and burners. Other than a badly adjusted flame, the main thing to watch for is a badly rusted out heat exchanger. But black does not mean rust.

My Atwood GC10A-3E will come on the first time I flip the switch. After that it will not relight until I turn it off and back on. When it relights it sounds like an explosion in the tube. I feel it is...


Sounds like some adjustments are needed. Air shutter for one, and ignitor/electrode. Have you by chance observed outside with cover open when it tries to re-light? My guess is that it is sparking/trying to ignite, but adjustments are needed for proper ignition. A good cleaning of burner tube, electrode, and proper adjustment of electrode & air mixture should cure your problem.

I HAVE A 10 GALLON ATWOOD WATER HEATER IN A PARK HOME THE PILOT LIHTS FINE AND STARTS THE GAS OK WATER IS NOT GETTING HOT IT LOOKS LIKE SOME OF THE FLAME IS COMING OUT OF THE HEAT TUBE GETTING CARBON ON...


I would definitely have the burner tube cleaned and adjusted if necessary. Sounds like a possible spider web in the tube, as well as have heat chamber blown out with compressed air if at all possible to remove soot build up. Stand back when blowing it out, or you"ll be covered in soot.
You can buy a long brush for cleaning barbecue burners, that work well.

I have a new Atwood 6-gal propane water heater (still under warranty). It works fine except that when warm water is flowing, the burner will start heating only after the water gets quite lukewarm. Can one...


If it's manual light, then only dial or lever on gas control is adjustable, and you can try turning it up a little at a time. It will increase water temperature so be careful, but that should also make it kick back in sooner as well. If it's electronic ignition, there is 2 or 3 heat settings available in thermostats ( little disc behind foam cover under pressure relief valve) . Obviously on those, if you choose higher temperature, it cuts back in sooner as well. If you have electric element, they have a thermostat on rear of water heater as well, behind electrical connection box. If your not 100% sure what I'm saying here, get back with model number of heater inside cover and I'll tell you your options. Please remember to be careful of scalding when you turn up the temperature.

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.

ECO failure. Replaced the gas control thermostat & vapor sensor


It sounds like your gas/air mixture needs to be adjusted. The flame should have just the slightest amount of white, at the very tip. The rest should be evenly blue. There is an air vent adjustment in the line to the burner, right after the gas input.
