Hey everyone Ive recently installed a used Vermont castings encore model 2250 and it appears to be in pristine condition but I'm having a hard time with a couple of things ...the primary control arm doesn't seem to have much effect..and without the cat engaged my burn times are horrible (three hours )chalk full of dry rock maple ...when I do engage the cat all flames stop and 60 percent of the time it just puts the fire out slowly and it fills the house with wood smoke odors ...all reply s are much appreciated..thanks
