2: Roof Mounting (Continued)
STEP 3: CHOOSE MOUNTING LOCATION AND LAYOUT
Collectors must be installed vertically, side-by-side, allowing at least 10
inches above the top headers for mounting of the reservoir and upper
roof jack. Place the collectors, reservoir, and upper roof jack in chosen
location as shown. Reservoir must be centered above outlet collec-
tor header. Bottom of reservoir must be at least 2 to 6 inches above
collector header as shown. Roof jack installs black side up, with hole
located near the bottom edge of a shingle. The reservoir rubber grom-
met must be higher than the roof jack rubber grommet. Mark the four
collector corners with chalk and temporarily move the collectors out of
the way.
STEP 4: MOUNT RESERVOIR
Mark locations of the two expansion reservoir mounting screws and apply
two quarter-sized dabs of roof sealant. Mount the reservoir with two stain-
less steel 3-1/2” lag screws (not provided) and two stainless steel fender
washers (provided). Snug down, but do not over tighten
.
Note: Penetrations of the building through which piping or wiring is
passed shall not reduce or impair the function of the enclosure. Penetra-
tions through walls or other surfaces shall not allow intrusion by insects
and/or vermin. Required roof penetrations shall be made in accordance
with applicable codes and also by practices recommended by the Na-
tional Roofing Contractors Association.
STEP 5: INSTALL UPPER ROOF JACK
Note: If installing a PV Panel, see Appendix on page 28 before proceeding
with this step. 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 penetra-
tion. 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
4” beyond the outlet end of the collector. 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 galvanized roofing nails (not provided). Be careful not to
put nails through the roof sensor wire. Apply roof sealant to the nail heads.
Apply roof sealant under the overlapping shingle and press flat.
STEP 6: 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.
