Stove used for this past season only, moderate use, basement location so I used to fire it up as needed. Cleaned pipe with vacuum (leaf blower trick) but could only sweep with a brush in the 3-foot horizontal pipe section coming outside (could not push brush through the 90 degree elbow). Had difficultly removing the cap on the tee in the back of the stove so I could feed the brush upwards and sweep the vertical section too so just left that alone. I REALLY caulked the pipe adapter to the stove very well due to leaks, so removing the t-pipe may be tough or impossible for me (if this is needed).....maybe pay a $99 fee to have someone else do this.....hmmm What other components (I know how to clean in the back of the baffle plate near the pot) i need to clean in the stove and how difficult on this model. Side panels slide open so that's a plus.... ..
