Vitosol 100-FM/200-FM Installation, Operating and Service
Install the panel array level or slightly inclined
approximately ½" (10 mm) towards the connection side
to ensure complete venting. Always locate an air vent at
the highest point in the piping.
Attaching roof brackets on shingled roof
1. The roof brackets 1 should be laid out as close as
possible to the dimensions shown in the chart on
page 9 for SV collectors, and page 10 for SH
collectors.
2. Locate the roof joist by tapping along the roof to find
its general location (stud finders do not work well
through shingles and roof sheathing).
3. Pry up the shingles and drill small pilot holes to
locate exact location of roof joist. If necessary, check
where pilot hole is coming through roof from inside of
attic.
4. Drill pilot holes into center of joist as shown. Fill the
pilot holes and coat the bottom of roof bracket with
silicone sealant.
5. Attach bracket to roof joist using the supplied 3.1"
stainless steel screws qP. Screws should penetrate
the roof joist at least 2½" (64 mm). Use longer
(field supplied) screws if required to achieve
necessary penetration.
6. Re-apply shingles, if required, and ensure all roof
penetrations are thoroughly sealed with silicone
sealant.
7. Continue with mounting rail installation on page 13.
IMPORTANT
The roof bracket must be securely attached to the roof
joist of the structure. Only use stainless steel attachment
screws.
The 3.1 in. (80 mm) screws supplied with the mounting
kit may not be sufficient length for some roof structures.
The installer must ensure screws will penetrate roof joist
sufficiently, and if not, must provide longer screws or lag
bolts.
