hello all.
new to the site. hope to get a question answered quickly as i'm in the middle of an addition.
installing a 90,000 btu furnace into an addition. calls for 82 cubic feet per hour. have a 50' branch run from meter. according to chart it should be 3/4"
my question is can i run 30' horizontal of 3/4" ips then reduce to 1/2" for my vertical run of 20' to the unit? or do i need to run 3/4" the whole way?
thanks in advance
