A 1500GS-AC installation roof mounted in Bradford Ontario done over the last weekend. The home owner had to move the intake up the roof because the attic outside wall would have interfered with the penetration. Silver jacket wrap was used to insulate the outside 5 inch pipe and wrapped twice to give an R8 insulated jacket.
A single collector roof stand at a 60 degree slope was used with flashing cones. Threaded rod employed for roof penetration on each unitstrut foot.
Inside the attic 6" rigid ductwork was used to gain maximum flow along with a 110 v powered AC fan and controls.
