Ok I am looking at installing a SP50 I have a brick chimney in good shape. I am looking at the 3" to 3" top vent adapter w/ the 3 to 6" top vent offset adapter. Then 6" black pipe w/ a 90 into the chimney. Does anyone have any thoughts on this?? The store is telling me this is not a good idea. says I should install a 25' flex pipe kit with the cost being another $350. any thoughts??
Thanks Steve
