Howdy!
Just thought I'd chime in, as I have the same stove -- drastically different climate though (I'd assume, based on the wood you have available!)
While I'm not sure how old this beast is, it is just a big steel box with a few doodads and bits in and on it. Your "wood burning too fast" issue is a familiar one to me. My priority was to be able to use it as my primary heat source (I have propane backup, but prefer not to use it). Obviously leaving well enough alone, even with a hefty load of wood (oh and the wood I use pretty much blows as far as BTU/cord -- fir, spruce, aspen), resulted in a cold stove in the morning. So I did the usual stuff -- check the pipe, clean the chimney, check the seals etc with little to no effect. So I had to get a bit more creative.
The damper on the stove has a bimetallic spring in it attached to the damper control rod. As the fire cools, the spring-actuator opens the air intake allowing more air in, thus speeding up/maintaining combustion. Even if you close the air intake lid it'll still pull air in and increase combustion. So after a few beers one night I decided to experiment and I clamped a small pair of vice grips on the control rod and just it hang, thus keeping the air intake valve shut against the will of the spring. Lo and behold in the morning: hot stove, easy to get going again. Perfect. Well, not exactly...
Doing this is probably NOT recommended by anyone in the "business" as what you're doing is forcing the stove to smolder all night. I accept this as I've gotten to where I can clean my chimney from inside in about 20 minutes (6" single to triple wall Duravent, 18' vertical run) and beleive me, doing this will force you to clean the chimney at least once a month if not more (when it becomes tough to light, decrease draw etc...time to clean). But -- I'm a career fireman so i can wathc my house burn down and know exactly why it happened!
glad to know I am not the only one who had cracks at the door corners
Another question, what is your stove outlet diameter? Mine necks immediately from 8" to 6" (at the stove) so this is part of my problem, as this creates a semi-venturi effect thus increasing draw. Also, is your pipe run OK? Does it go single wall to the (first) ceiling then double or triple up and out? (Mine originally went single to double to single to triple....bad creosote situation there....but it heated the heck out of the upstairs
I fixed it.)
Anyway, good stove: strong like bull, smart like...bull. I'm thinking of upgrading to a more modern catalytic model, but who knows. Mine has cracked at all four door corners (on the stove itself) which I just welded back up. Made it look meaner....ugly like bull. So...that's my two cents!
