Metal or Tile Installation

NOTICE: Be sure the flat side of the vertical support of the extrusion faces toward the collector location and the “U” shape opens toward the lower roof edge.

1.Mark tank location on roof with front foot of tank located directly over reinforced roof area.

2.Measure 82 inches down roof from front foot of tank to determine location for Collector Extrusion.

3.For Tiled roofs, remove tiles to allow for room to screw collector straps to rafters or trusses. If installing three collectors, remove tiles for third collector strap.

4.Slide the Collector Extrusion on to the Collector Straps. After leveling, raise the hot pipe side of

the extrusion by 1/2” per collector to ensure correct operation of the system (eg. For a 2 collector system, raise the hot pipe side of the extrusion by 1”).

6.Attach straps onto rafters or trusses with 5/16” x 6" lag screws.

7.Replace tiles that have previously been removed.
