Thanks. I did find some text like references at the library which I am
digesting now. Son goes to local CC so I'll ask him to check out texts there
as well. Thanks again.- Dan

Dan;

Go to your local community college book store and see if they have
anything
on HVACR. You might be surprised. And bring your wallet. The books
aren't
cheap, but they'll be extremely helpful.

A few days back I asked a question about my gas furnace problem. It seems
I
may have triggered some kind of automatic troll alert or something. How
might I rephrase my question to warrant a sincere response. Even if I am
an
old hack asking a stupid question, I'd still like to know more about the
problem if anyone knows. From other questions and responses here I am
sure
some know and that my question is no more off-the-wall than some of the
others. Well, I'm off to the library to see what I can find there. Many
good
and interesting posts here, so I'll keep reading regardless. -Dan
