Any details on a Republic Gyroscopic-Balanced gas furnace

Doug_24

I'd like any info on the Republic Gyroscopic Balance gas forced air furnace installed in my home in 1965. On the access door of the furnace it says "Constant Heat-Constant Circulation-Constant Comfort". It was manufactured by the Auto Gas Company of Bellwood, Illinois. My dad built this house and had this furnace installed and said it was really fancy for the day and I think it is still amazing. From what I can gather (from my Dad's recollection and my inspection of the components) is that it has a variable speed fan, variable flowrate gas valve, two thermostats (one upstairs and one in the lower level) and two zone control damper actuators. Apparently, it sets a gas flow rate that balances the heat loss from the house. This furnace is really well built and it still runs, although the damper actuators and the variable speed fan are not working. It seems so far ahead of its time even today. I have a model LB-125, Serial No. 8186.

I'd like to get any info on this furnace such as sales pamphlets, manuals, adverts, etc. Any chance there are still spare parts available?

I do not have info on the Furnace

but I do have info on Republic Gyroscopic Gas Conversion Burner somewhere in my vast library. I will have to look for it.I believe is probably the same technology you have in your furnace. It was way ahead of its time and was actualy able to be set up to be able to go from a low fire and modulate to a high fire operation based on demand. Most of them do not work that way anymore and are now set for just high fire.

Does it have a stack of ceramic burners that look like a "bee hive"?

If you will e-mail me at gastc@cox.net and give me your postal mailing address I will make copies and send you what I have. I just pulled the book down from my shelf and I have quite a bit of information but not exactly on the LB-125 model furnace. I do have some info on furnaces however model L-125, l-180, G-95, FH-87, FH-125.

This system was used on furnaces, boilers both gavity and FHW also steam.
