i have a woodburning fireplace insert in the house we just purchased, the chimney is showing signs of age (hairline cracks in clay liner) after reading up on this i am under the assumption that when inserts are installed now ( this one is probably 30 years old) that you install a chimmney liner to reduce the flue size because of the more efficient burning. my chimmney has an 11 inch square flue, i installed a 6 inch pipe as recommended on various chimmney liner retailer sites. however i have not installled a complete flexible liner all the way up ( 25 ft chimmney) i installed 6 ft of rigid stove pipe in the flue to get gases into the beginning of the clay liner. this was the way that was recommended several years ago, now they recomend liners all the way up. here is the problem, i hardly get any heat in the room when burning this, if i shut the top damper i get alot more heat, but i can't shut it more than say 1/4 inch or i get smoke rollout, i also cant open more than one door on this insert or i get rollout even with damper wide open. is this normal? i understand this is draft related but the people who lived here before burned this for 30 years, i can't believe it did this always? i would think that me installing the pipe improved the draft by sizing the flue more correctly to the insert.

can players on different systems play together online if they are using say, wii, ps3 and x box 360?
