Hi Cindy,
You may be able to get some assistance by going to the Atwood site and downloading the pdf service manual for your unit.

Hi Cindy,
You don’t have to pull a fuse. Shut off your propane, drain the water heater, remove the main burner and thermocouple/pilot assembly again, undo the propane line to the gas control valve. The entire square valve removes counter clockwise, It will be a tough turn at first because it’s probably been in there a while. (if the water heater is over 12 years old I suggest replacing the entire water heater because the aluminum tanks usually last 10-12 years) You can buy a special wrench at the hardware store to grab the square gas control valve easier. The new valve will look different!! They did away with the blue knob versions years ago. But the new valve is better and the connections are the same. Use teflon tape on the new valve and use the special wrench to reinstall it. This is a great time to flush the white corrosion out of your water heater tank also.
Good Luck

Loud is ok, actually better. A quite lazy flame on the water heater is actually using more gas to heat because the flame is not as hot. You want a nice blue flame that sounds like a jet engine for the most heat and best efficiency. Don’t would about the gas burner fitting all the way onto the brass elbow, it just doesn’t. Sounds like you are back in the hot world again. Enjoy.

Hey, can I jump in here?
I was just wondering… Why don’t people (meaning factories or us, the full timers), why don’t we put in tank-less instant hot water heaters? Is it to much current draw for solar? Or is going without that propane back-up just to scary?
Anybody know?

Ya, they would draw too many amps if electric but there are propane ones for RVs. For me it would be the expense to swap it for a working water heater, but if our water heater fails I would definitely look at them as a possible replacement. Seems like a cool idea, but I would have to study the pros and cons.
RVHH Chief Cook and Bottle Washer - LoveYourRV.comI’ve been researching this in the process of gathering information for our new house. While they are energy efficient, they are not water efficient. The heater doesn’t come on until the water flow reaches a preset level, so you would end up running the water to activate the heater, and then wait while the warmed water purges your lines. Unless you set up some kind of bypass to return the water to your tank, this setup would be terrible for boondocking. I wouldn’t be comfortable returning heated water to the tank, sounds like a recipe for bacterial growth.
I agree with Roger and Sue, tankless water heaters use WAY too much water. I have one in my house (we have 3 daughters that take showers before I do) They are great for endless hot water but you waste a huge amount of water waiting for the water flo meter to turn on the heater then the water to heat in the chamber, remember the chamber is full of cold water which has to run through the lines before the hot water can make it too the faucet. If you are dry camping you would waste all your fresh water. AND you can not dribble tankless hot water, you have to turn the hot water on full to get the heater to come on, if you dribble the hot water faucet the water stays cold.
Solar tanks on the roof would be an idea but we live in the NorthEast and would not be practical.

Thanks for the info, wasting water would be a very big con for me.
