I'm putting a dryer vent on the second floor of a new home and would like to know if there are any code restrictions in (Taunton) Massachusetts that would prevent me from running it up to the attic and out an eave vent. The only installs i've seen run into the attics have been in second floor condos where fast- paced sub.'ing was obvious and the flex blew right into the attic. I was thinking of putting a cleanout tee on it, too. Any suggestions?
