I am curious I have a 3 year old Enviro meridian and was curious if any one else who has a enviro has had the air damper control slide set up or get hard to slide. I cleaned the stove end of season in June this year and when I went to start it up this year it was sticking but it seemed to loosen up after I burned but went to adjust it a tad today and it is setup again. I was just curious someone must have or has had this happen and what did you do to rectify it. Thank you
