Start by taking an 18” pipe and attaching a Side Outlet Tee (681-604HC) to each side of pipe. You will want both 90-degree openings to face the same direction. Make sure the vertical holes are not blocked, then tighten set screws. Build this step twice.
Take (2) 24” pipes and attach them to the brackets built in the first step. Make sure the vertical holes are not blocked then tighten set screws.
By the end of this Stage you what you built will form a square,
Take (4) 36” pipe and slide one into each vertical hole of Square built in stage 1.
Measure 10” up and tighten set screws.
Cap the top and bottom of 36” pipes with Flanges (683-104HC) then tighten set screws.
