Installation on Shingled Roof
(continued)
Always locate an air vent at the highest point in the piping.
Attaching roof brackets on shingled roof
1.
The roof brackets
should be laid out
as close as possible to the dimensions
shown in the chart on page 9.
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
appropriate stainless steel lag bolts
or screws (field supplied). Lag bolt
should penetrate the roof joist at least
2½” / 64mm.
6.
Re-apply shingles, if required, and
ensure all roof penetrations are
thoroughly sealed with silicone sealant.
7.
Continue with mounting rail installation
on following page.

Drill within
0.2” / 5 mm
of center.
The roof bracket must be securely
attached to the roof joist of the
structure. Only use stainless steel
attachment screws. Do not
overtighten lag bolts as the head may
weaken and shear off.
CAUTION
The 3.1” / 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.
