Welcome to the Forum!
Getting used to your new Hi-Lo can be a bit confusing but broken down the basics is quit easy. There are several things you can do to make getting started easier. The Forum has a reference library that you will find at the bottom of the main page. There you will find a long list of different subjects pertaining to Hi-Lo. I will get you to the manual, which may not be for a 1994 but will be close enough, they are basically pretty much the same.

There are also postings for the appliances like the water heater, furnace, fridge, etc. You can also find many of the manuals by going straight to the manufacturer's websites and down load for your particular model.
Youtube has a heap of info that can be used to help.
Last but not least there are a lot of forum members here that are happy to answer your questions. You're already started down that road.
Good luck!!!
