5.1 Installation of 45° Mounts on Roofs, Walls,
or Ground
IMPORTANT: INSTALLED HEIGHT MUST NOT ExCEED 60 FEET.
CHECk THE ROOF STRUCTURE TO ENSURE PROPER SUPPORT FOR
COLLECTORS, MOUNTING HARDWARE, WIND LOADS, ETC. (STATIC
CALCULATION REqUIRED; IF NECESSARY, CONTACT THE BUILDER).
ALL ROOFING WORk MUST BE CARRIED OUT BY A PROFESSIONAL ROOFING
CONTRACTOR. WHEN WORkING ON ROOFS, OBSERVE ALL RELEVANT
SAFETY REGULATIONS, IN PARTICULAR: “SAFETY REGULATIONS FOR
WORk ON ROOFS” AND “SAFETY AND RECOVERY HARNESSES”V (OR LOCAL
REGULATIONS).
INSTALLERS MUST COMPLY WITH ALL LOCAL, STATE, AND NATIONAL
CODES.
ROPE MAY BE USED TO HOIST COLLECTORS, BUT MUST NEVER BE
ATTACHED TO THE COLLECTORS’ PIPES.
WHEN WORkING ON ROOFS, ALL RELEVANT SAFETY REGULATIONS MUST
BE OBSERVED.
Designers and installers should consider how rainwater, snow, and
ice accumulation is affected by the installation of the collectors and
mounting hardware. Collectors affect the flow of rainwater around
them, so appropriate means for conducting the water away from the
vicinity of the collectors must be provided. Collectors and mounting
hardware are also subject to accumulation of snow and ice in
cold climates. Installations must provide protection to people and
structures below the solar collectors to avoid hazards due to falling
snow and ice as it melts (or is blown off by winds). Installers must
also consider the possibility of snow and ice falling onto collectors
from any structures located above them and provide appropriate
means of protecting them.
Building materials adjacent to solar components must not be
exposed to the elevated temperatures that the collectors can
generate. Exposed components (that can readily be reached) must
be maintained below 140°F or otherwise be insulated/isolated. All
other exposed surfaces that can exceed 140°F should be labeled with
appropriate burn hazard warnings.
Tools Needed:
1. Power drill with 1/4” drill bit. Bits of other sizes are
recommended as well.
2. 11/16” drill bit for corrugated sheet roof installations.
3. Two 17mm wrenches and/or sockets for M10 bolts.
4. Two 15mm wrenches and/or sockets for M10 nuts.
5. Two 7/16” wrenches/sockets for 7/16” and 1/4” nuts/bolts.
6. Two 9/16” wrenches/sockets for 3/8” nuts/bolts.
7. One 2” adjustable wrench for collector fittings.
5.1.1 Mounting on a Flat Roof
Two mounting frames are available for fixed, 45-degree collector tilt:
• R1 for one collector installed vertically (185545). See Figure 4.
• R2 for two collectors installed vertically or one collector
installed horizontally (185546). See Figure 5.
Figure 4: R1 Mounting Frame for Vertical Collector Arrangement
For 45° vertical mounting on a flat roof, two sets of (185543) flat-
roof/wall mounting hardware are needed; for two collectors or
more, the number of sets required is the same as the number of
collectors. See
Figure 6.
For 45° horizontal mounting on a flat roof or a wall, the number
of BF W (074324) flat-roof/wall mounting hardware sets needed is
twice the number of collectors. See
Figure 7.
2 30° mounting is not recommended for wall mounting without additional
supporting structures.
