Pretty much as described above. From what I read in your post, it sounds like you are having trouble getting the gas to light off. Three things to look at. First, be sure the propane valve at the tank on. Secondly, there may be air in the line that will take some time to bleed out. Thirdly, it is very possible that spiders or other insects have clogged up the gas orifice at the HWH. You can take the orifice out and clean it. As for the electric part, it will heat the water but much slower than the gas. Also for the electric to work, you have to have the master switch turned on at the tank. Its a rocker switch on mine. Hope this helps.
