i just installed the vent kit on my spare stove and am unsure about the clean out tee. there is a short three inch run with a cap on it that fits into the bottom of the tee. im getting alot of smoke out of the bottom of this on start up. its hard telling how much carbon monoxide is coming out while its running? its not setting off any detectors yet. whats the best way to seal the bottom? i recently read that sealing over the rope gasket will effect the pipes cooling performance. the little cap on the bottom is riveted, so it cant be removed and seal. the only way to seal that cap from the bottom is to cover the rope gasket, so you can see my delema. i would have gone with selkirk but i got this kit for $100, so it was too good to pass up.
