Installation Steps for Pitched Roof Mounting
1. Locate and mark the roof rafters into which the solar collector mounting brackets will
be mounted (one way to find rafters is to see the
“tails” at the edge of the roof).
2. To create a set point for plumbing and level installation, measure the distance from
the edge of the roof to the desired mounting points and mark the points where the
collector mounting brackets will be installed (fig 1.2).
*Note: you need to install a screw into one of the holes in the mounting bracket, not
both holes (fig 1.1).
* Note: for collector model 7000
upper and lower mounting bracket should be 78”
apart measured from top of top bracket to bottom of bottom bracket.
* Note: both the bottom and the top mounting brackets should be placed as per figure
2.0 from each other as possible in the width dimension.

3. Determine where penetration will be to connect the solar hot water collector with the
storage tank and/or the water supply (use 2 pre-
insulated ¾” steel flex hoses or 2
insulated ¾” copper pipes for that connection).
Note: *For a two-collector system that will be elevated above the roof surface, a good
location for this penetration is directly between the two collectors.
