I am just getting set to go on an camping trip and running things on the driveway right now. I don't have propane turned on so when I turn on the interior switch for the HWT I get the DSI FLT light (which I assume means no gas to the HWT. Will the HWT work with the outside switch on (controlling shore power) and the inside control panel switch off (does this just control propane use or overall use?)
Yes, the on/off switch in the outside panel controls the electric mode (120V).
Yes, the DSI FLT is due to the propane not being on (since the inside switch is to control the propane hot water heating, not overall function).
Yes, it will work with the outside (120V) switch on and the inside switch (propane) off. In fact it works in any combination - only outside (120V), only inside (propane), or both on (and then it heats up faster!).
