Hot Water Tank

[Hankster]

My hot water tank won't ignite on propane. Works fine on electric, but won't fire on propane. I can see the igniter flashing like crazy, but there doesn't seem to be any propane to ignite. Any suggestions?

Had the same problem, make sure your propane is on and it works else where, such as the stove. If it works you might inspect the orifice tube, I have had a spider build a nest in mine and it would not ignite. Blew out the orifice and it worked fine. Incidently, the spider built the nest between cycles of the HW heater as we were using it while dry camping at the time.

Do all the other gas appliances work? If not check the LP Leak Detector. If it's off the solenoid valve from the propane tank will be closed. If this is the case turn it on and it will flash, then the valve will open.

Thanks for the tips. The furnace worked just fine and when I lit the stove, which took a bit of time, I also got the hot water tank to work. Could have been air in the line, I'm not sure, but it is working now.
Thanks again. Getting ready for "The Rally" in Redmond Oregon.

It takes longer to purge the air out of the line to the hotwater heater (tank) than it does anything else.

One more question, now that my hot water tank is working on propane again, I get a whistling sound coming from either the propane tank, or the hot water heater when the hot water tank is lit on propane. Any ideas? Should I be concerned?

My cub was always hard to light the hot water w propane at first. I would light the stove top that seemed to purge the lines.
Then run the fridge, from then on hot water would work fine.

HI
Is there any way to adjust the temp on the hot water heater in the 2011 378? I am going blind reading the manual.

[polkatronron]

No there is no temp adjust on these. Mine would not ignite well and then would not stay lit...the problem was the ceramic around the igniter wasn cracked.

The thermostats installed in the hot water tanks are 120° for the 12V (GAS) and the 110V thermostats for electric . Yes, there are two one for 12V (gas) and one for 110V ELE, at least on mine, Suburban SW6DE.

Sometimes when the thermostats are installed, the sensor plate is not mounted flat against the surface of the hot water tank on the mounting stud. It may require slightly enlarging the stud hole so it will fit flush against the tank wall on both thermostats. I researched the thermostats, found there is a 140° available for the 12V and 120V. Replaced both with the 140°, now I have plenty of hot water on gas or electrical. With hotter water, you just have to use more cold water.
