2: Roof Mounting (Continued)
STEP 3: CHOOSE MOUNTING LOCATION AND LAYOUT
Collectors must be installed vertically, side-by-side, allowing at least
6 inches above the top headers for mounting hardware. Place the
collectors and upper roof jack in chosen location as shown. Roof
jack installs black side up, with hole located near the bottom edge of
a shingle. Mark the four collector corners with chalk and temporarily
move the collectors out of the way.
STEP 4: INSTALL UPPER ROOF JACK
Chalk mark the location of the upper roof jack hole. Break the glue line
between the shingles by sliding a large putty knife between the shingles.
Loosen just enough to fit the roof jack underneath. Insert rubber grommet
into roof jack from underside and slide roof jack into place to check the
fit and the chalk mark. At the mark, drill a 1-1/4” roof penetration. Attach
the provided wire connector to the roof sensor lead wire and feed the lead
through the hole. Leave enough lead for the sensor to reach 1’ outside the
roof jack. Lift shingle and apply a large bead of roof sealant completely
around the hole and the lead wire. Slide roof jack into place under the
shingle, with lead wire protruding out under lower edge of jack. Press
down into sealant to ensure a good seal. Secure roof jack using galva-
nized roofing nails. Be careful not to put nails through the roof sensor wire.
Apply roof sealant to the nail heads. Apply roof sealant under the overlap-
ping shingle and press flat.
STEP 5: INSTALL COLLECTOR HEADER STRAPS
Replace the collectors in the chalk marked location. String the sensor
lead wire underneath the collectors with the sensor protruding at upper
collector outlet end. Apply a quarter-sized dab of roof sealant 3” above
the end of one of the top headers. Place mounting base over sealant
and drive a 2” lag screw (not provided) through the base, securing so
that strap can run vertically through the slot. Wrap a short header strap
around header and lay into the slot in the base. Screw on a cap until
tight. Be careful not to cross thread. Continue with the installation of
remaining header straps at both ends of each header.
