Metal or Tile Installation
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.
8. Flash and seal all roof
penetrations.
9. Continue with Collector
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.
