Do you know where I can find a diagram showing the interior design of this stove. I've found out just about everything other than the manual and how the stoves design actually works. It looks like a pretty generic design with a lot of similarities to a lot of stoves. That often means that it works well enough to have multiple copies/versions of it. I'm assuming that this stove is now a Century High Efficiency EPA Stove model S244E. It looks like a nice little stove with a good fireview window. I only need it to heat about a thousand square feet. Specs: 74.5% e rating, 18" logs, 26100 BTU/hr, up to 1000sq ft. Haugh's model S244E. Would anyone be willing to share info about this stove. Seems like a good little heater.
