Suburban Woodheater Advice

I was just given a Suburban cabinet Woodheater this is a new animal for me. My wood burning history in terms of freestanding stoves has only been with newer high efficient stoves. I installed this in our basement and I'm looking for info about the unit. Looking for specs such as estimated burn time and btu rating. The back plate shows the model as a Suburban WC6-88. Any info would be appreciated. Gaskets and firebox are in tack, no cracks and blower works.
