Hi. I bought this insert used ($500) 25 years ago to put in the basement of a house I was building. The fireplace hearth was built to fit this unit, and it has been working fine all these years. I recently repainted the unit, so it was partially disassembled but not completely removed to see the back panel where I suspect the ID tag is. The rheostat works to adjust the fan speed but does not allow the fan to be turned on/off so I just plug/unplug to use it. I've been researching the Lopi discontinued manuals site and think it might be a 1984 LX model but the manual indicates a couple discrepancies:
1. The refractory baffle has an L shaped angle iron instead of T shaped and there are only 5 bricks
2. There are no air tubes along the refractory baffle
3. There is no "Start-up Air Override" and the rheostat control is on the right side of the blower assembly
My goal is to order a new rheostat to get this working as new. Any help would be appreciated. Thanks for looking
