Step Three: Hold-Down Strap Bracket Locations
Locate the Hold-Down Strap Bracket holes using the information in
Table 2A
shown below
.
Measuring from the
top outlet header bracket chalk line, snap another chalk line parallel to this line using the “A” distance. The “B”
distance is the same for all collector sizes,
which is 16” (40cm) up from the outside of the bottom header
and can be measured after the collectors are installed. Wait to install the Hold-Down Strap Brackets until after the
collectors are installed so as not to damage the collectors when you are bringing them to the roof for installation.
