Hi David, I see this is your second post... so welcome to FiberglassRV. We've found most brand owners manual to be sadly lacking. Fortunately, these eggs are more alike than different, even if one is kinda square and another is a bit rounded. We have pretty good documentation going on in the Document Center. Write down the brand/model of your appliances, then see if there's anything here that will help you:
Fiberglass RV - Document Center If there's not what you need, post back and I know the generous membership will try to help.
Again, welcome...
