Alternate Collector Mounting Methods:

The Easy Way, (avoids having to locate rafters):

In areas with average wind conditions, (Highest winds up

to 75 MPH) the light weight of the collector allows you to

use “Hollow Wall Expanding Anchors.”

If using this method, be sure to use the ¼” size bolt.  Drill

a ½’ hole through the sheathing to allow for the thickness

of the anchor. Place the anchor in the hole, pull the nut end

up, using the supplied ¼” bolt, until it is tight, but do not over tighten!

For high Wind areas, use a lag into a “Spanner Board” between the rafters.  For extra strength the spanner boards can be toe-nailed into the rafters.  Another option is to use a “J” hook around a rafter but location options are limited with

this method.
