Old reznor heaters

[signcrafter]

We bought a house this past year that came with a reznor heater. It's an older ugly greenish color one. The cover over the controls is missing and I'm pretty sure that is where the model and serial number are so I can't figure out that info. The closest thing I could find searching was an auction for a model LUS-201-F, not sure if that's the model of mine or not but it looks similar. https://www.bigiron.com/Lots/ReznorLUS-201-FNaturalGasShopHeater. I don't know much about these heaters and would like to learn a little bit about them and how they work in case I have a problem with it in the future. This winter it worked great and really heated up the shop nice.

Anybody have a similar heater or know about them? Know where to find any manuals on them if possible? From my searching it looks like reznor says all parts and manuals are discontinued. But thought maybe someone might have some info or know of somewhere online that has some info.

Thanks

Picture(S) would help greatly. I have a few Reznors that I take care of at work.

I will try to get some pictures later today. But it looks very similar to the one that I linked to that has a bunch of pictures of it.

We had a few of the same vintage in our warehouse until a few years ago.

Upon inspection, every one of them had a cracked heat exchanger.

I'd suggest you have yours inspected by a qualified HVAC person before spending any time or effort on the unit.
