Hi, I have an old Atwood gas water heater (model j81 I think) this is a manual unit which we have to light the pilot light on. It will light and we can heat water for a short time only before it goes out completely. Any ideas on how I may solve this problem? Thanks

That is not a model number that sounds familiar. Should be a tag on side of water heater behind cover, outside. If it has the little arm adjustment for temperature on top of gas valve, simply move it over a little to the left to increase water temperature, and try it until temperature is what you are happy with.
I'm assuming when you say it goes out completely that the pilot remains on and water heater re-lights when called for? If you adjust that temperature lever over, and water still doesn't get hot, you need to replace gas control, as thermostat is built in to it.

    Hi. I am also working with my Jade J81 with varying success. I think I once solved the problem you are describing! I think the pilot flame is too weak! THere is an adjustment screw hidden behind the threaded cover cap marked "PILOT ADJ". Turn that slightly counter clockwise and the flame will increase. If the flame does not respond much, then remove the entire module with the thin pilot gas pipe and ensure the front part is clean and free from dirt.

    I have another question to anyone that may know! There is also an adjustment marked "VENT"! What is that? What functions does it have in the system? Thanks. Fredrik

Converting Atwood RV Gas hotwater heater with Electric ignition with a Gas/Electric

If they are on outside of tank , I'm thinking your new tank has motor-aid feature as well. That is used to circulate coolant through from engine of motorhome while driving and it keeps water heated. That feature usually adds to price of tank. Hope you didn't pay for some feature you"ll never use.

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.

Atwood G6A manual water heater had gas flare up around the control knob when lighting the pilot. Unit is about 9 years old so repair or replace? works OK & no gas smell.

The gas control is leaking gas around the knob?
The gas control needs to be replaced before causing explosion and/or fire.
Gas control has identifying marks on side.

I have a Jayco pop up with an Atwood water heater, serial # 37C14U-5. My problem is two-fold. The water heater pilot doesn't stay lit after initial run, and propane is leaking out of the vent on the...

Leaking propane is red flag #1 and fire hazard.
Immediately update your insurance and then turn off gas.
If pilot is not staying lit, then gas leak can be cause of pilot problem since pressure on the line is reduced.
Other causes include bad gas control valve, air in the gas line, bad thermocouple, burner parts need cleaning, or all the above.
After fixing leak, replace thermocouple, clean combustion chamber and burner parts, and bleed gas line to remove air.

Atwood gas waterheater with white rodgers gas valve pilot hard to light and not a big enough flame to touch the thermocouple

I think you need to reposition the thermocouple, or adjust the pilot gas pressure by adjusting the pilot screw make sure it is still the recommended gas pressure of the system... please contact a HVAC tech if this things did not work.

the gas valve is what you need to replace, the thermocoupling only tells the gas valve that it is ready for a flame and lets a little gas out, but the gas valve is not letting the gas out,, there is a screen in the gas valve it may be clogged not letting the gas thru, but at the age of your unit I would even consider changing the unit insted of investinf more money into this one

After a few minutes of burner heating the water, gas shuts off.

A couple of things to check:

If possible, remove the pilot gas assembly and clean the gas jet and thermocouple - they can get carboned up and stop working properly. Make sure the pilot flame and deflector is aimed properly and making the thermocouple glow red hot. If the problem persists, you may want to replace the thermocouple and also check the propane regulator.
