I have been so particular about my stove, read the owners manual several times over as well as many posts on here about the operation, so tonight I finally decided to light my stove for the first time this season, made sure the damper was all the way open and loaded the stove with only about 4 splits, its not that cold tonight, started the stove. All seemed great, temp climbing, nice flames, waited 15 mins and closed down the damper to about 2 and waited till stove top gets up to temp to engage cat, all great so far, right? Thats what I thought, stove top reached 250 in about 45min so I engaged cat, or so I thought. Looked in the stove expecting to see a lit cat and nothing....Hmmm, went outside to check chimney and smoke rolling out so I know cat is not working, well, I went back inside to check again and that's when I realized what I did, the cat was engaged already, I don't know how it happened, been like that all summer, I overlooked it, something that important, I missed....I can't believe it...I wanted to do everything by the letter, I'm in shock. Well, I reengaged the cat again and it seems to be working fine, red glowing and no smoke. I hope I didn't damage my cat. I feel so stupid.... :grrr:
