 quick update
OK I couldn't wait for a reply because I realized i had the old furnace setting outside and could check my idea. It does have a brass fitting with a smaller hole in it screwed into the end of the tube. I took it out screwed it into the new unit and fired it up, and now the 1/4 foot dial went from 4.5 secondds to almost 12 to make a full turn and ther is only a 1 foot dial and it took a little over 46 seconds for a full turn.
OK so the BTu ratings are 90,000 in and 72,000 out.
the orifice that it calls for says drill size #15 for N gas so i don't know if the old one is right or how I can check it. Does that corrolate to an actual drill bit at the unfluted end?
anyway I'm sure this is going to need cleaning since it had been running for at least 3 months with no regulation.
what would anyone suggest as my next move? do i just need the right orifice and someone to come and do some adjust ments, or has running it wide open messed up some parts with carbon buildup or something? what would someone think a target time would be for the gas usage dials?
Thanks everyone for such a great forum and all the help I have received in just a matter of hours! You all ROCK!
