COLLECTOR ROOF MOUNTING – SHINGLE ROOFS
(CONTINUED)
d.
Peel off the protective paper and firmly press the RT-Mini onto the roof
making sure the butyl sealant has adequate contact with the roof surface.
Slide the stainless steel ¼-20 hex bolt into the top slot in the RT-Mini. (Fig. 6-A)
e.
If mounting into the roof truss install the (2) included M5 x 60 mm (#10 x 2.375”)
wood screws through the two holes in the center of the mount. (Fig. 6-C1) If deck
mounting, then (5) screws are required with (4) on the outer holes one in a center
hole of the mount. (Fig. 6-C2)
•
Deck mounting requires that the deck be minimum APA-rated 7/16” OSB or 15/32” plywood.
•
For metal roofs pre-drill screw locations with 1/8” drill bit.
f.
Ensure that the screws are properly tightened and that the rubber
washers on the screws are compressed. Do not over tighten.
g.
Apply roof sealant to the top and each side edge of the brackets. (Fig. 6-D)
h.
Once the RT-Mini is anchored into the roof attach the Gator Clamp by placing it on top of
the RT-Mini with the stainless steel ¼-20 HWH bolt coming up through the hole. Fasten
the mount by tightening a stainless steel 1/4-20 hex nut onto the bolt. (Fig. 6-A)
7.
Install (2) #6 x ¾” stainless steel screws to secure Gator Clamp assembly.
8.
Attach the bottom manifolds of the collectors with PPCs.
9.
Locate and mount the Bottom Gator Clamps (two per collector) along the bottom manifold,
aligned with the Gator Clamps on the upper manifold and install as the Top Gator Clamps
were. The Bottom Gator Clamp is longer to allow for thermal deformation of the collectors.
10.
Attach feed and return lines following the Heliocol published guidelines.
11.
Pipe supports should be used at the feed and return
piping connected to the collector banks(s).
