Hot Water Heater Help - '98 Intrigue

April 10, 2011, 03:54:55 pm

I'm not sure if you folks with new coaches have the same hot water heater I have, but I need help with mine. Maybe some of you "mature coach" owners can help.
I have the Atwood Model G-10 (MPD 93756). I think I'll need to replace it. I have a mobile RV tech coming over Monday afternoon but I'd like to be prepared.
Any tricks about removing/installing? My original installation manual makes it look pretty "easy", but it seems things with motor homes seldom are.
Has anyone had to replace this model recently? I'm wondering if I am going to have difficulty finding the exact model. Have any of you had to change models? What should I look for?

A Google search for MD 93756 wasn't very helpful.

Thanks, Jim

Try http://www.americanrv.com/ for info on water heaters and parts.
They will provide a reference on availability and price.
Unless your current heater is leaking, it can probably be repaired by a competent tech.
The cost will probably start around $100 for the service call plus parts and additional time.

Jim,

You do not provide your coach year, but assuming it is as old as my 2002, I can tell you about what is entailed since I did this last year. It is pretty straightfoward with one exception which I will explain. Obviously, you empty it. You kill the power at the breaker. You turn of the propane at the the tank. You remove the access door on the inside. You remove the screws from the outside. You will have to break the sealant seal they use with something like a putty knife. You disconnect the gas line, the water lines, the electrical lines, etc. If you have the model with the Hurricane loop welded to the back, do not disconnect those until you pull the heater since some coolant will run out. On my Magna, CC was nice enough to leave plenty of extra coolant hose so an assistant could hold the tank outside the hole while I disconnected the coolant lines. The install is the reverse. You bend the performated metal tabs and be sure to use new silicon sealant around the outside lip.

It is not hard, but you will need an assistant at certain stages.
The one potentially tricky thing is that if you have an older model with one switch for gas and two 12v wires, all the Atwoods available now have two switches and three wires. You will have to run a third wire to the new switch and enlarge the switch hole in the cabinet. Depending on where that is located relative to the heater, that could be tricky. I managed to do it. That part took many hours of study to determine a route to avoid drilling holes (just one in an interior cabinet. You can always mount the new switch near the new heater.
Nice thing is that you can now control both the electric and the gas from the switches.

I believe I got mine from PPL Motorhomes. They had the best price.
