water heater

Blissful, again!!  When using lp to heat water, do you turn on the switch to the left of the sink on front panel?  Or, is this "on" switch for electric/both.  I am very confused!!  The red a"reset" light does not come on.  Still trying to locate the "on" switch in the outside compartment....if I find it, do I leave it on all the time?  Grateful for any lessons here as the manual that comes with my pod is a JOKE!

To add to what jato said, the red light may come on for a few seconds when you first turn it on.  It may also come back on even if you have propane if the flame gets blown out by the wind - but the system will relight it quickly.

You can use the electric and propane at the same time if you have electric hookups - it will reheat faster and then will maintain the temperature using the electric (its thermostat is set higher than the propane system).

When you open the metal cover outside, look in the lower left corner for a black switch.  You can leave it on all season, but make sure you turn it off before you drain the tank at the end of the season or the element will burn out immediately.

What 3 valves are you talking about here?

The "fun" part is getting to the valves.  If you are small and a good contortionist and don't mind tight areas it is easy.  Just loosen the 4 screws to the right of the water heater - in the thru storage area in the back of the pod.  Then you reach your hand into nowhere and try your best to reach and turn the 3 valves.  OR  Lift up your mattress and cut an access hole so you can easily do this procedure and see with your eyes what you are doing.  I cut my access hole about 5 " wide by 6 " long and then cut a 1/4"thick piece of luan to cover the access hole and used 2 wood screws to hold it down
