I'm hoping that someone can help me. I found an Upton 207 pellet stove on craigslist but I can't find any documentation on it. The company was bought by US Stove and they only have the manual for the more recent version which shows a digital display panel and the one I looked at has manual switches (so it must be older). Does anyone have experience with this stove? I'd appreciate any knowledge that you can share. Thank you!
