Installed Natural Gas 90+ furnace on the upper deck of my shop/pole building 32x40 ft. ran 12" round duct. from furnace down center of trusses. for 12 ft, then 10" for another 10 ft. then 8" for another 10 ft. to almost the end of building between 2 10x10 service doors, capped off the end of the run. Will it heat O.K. if i cut holes into side of ductwork with holesaw angled down toward sides of building? or should i run short ductwork off of this main run? Building has 2 in. styrofoam on sides & ends and 1/2 in. under tin on roof? Thanks! Gene
