SOLAR COLLECTOR FLAT ROOF MOUNTING INSTRUCTIONS

CAUTION

ALL PERSONS WORKING ON ROOFS SHOULD

HAVE SUCCESSFULLY COMPLETED A FALL SAFETY

COURSE AND SHOULD BE PROPERLY EQUIPPED

WITH THE APPROPRIATE SAFETY EQUIPMENT

WARNING

AFTER COMPLETION OF THE COLLECTOR
MOUNTING AND PRIOR TO SYSTEM CHARGING THE
COLLECTORS MUST BE COVERED BY A BLANKET OR
OTHER MEANS TO AVOID SOLAR RADIAT ION FROM
HEATING THE COLLECTORS. THE SURFACES OF THE
COLLECTOR CAN BECOME EXTREMELY HOT AND
COULD POSE A BURN HAZARD.

The most important structural consideration is to securely
anchor the solar collector and the mounting hardware to the

structural members of the roof with the stainless steel hardware
provided. The solar collector must be attached to the mounting
hardware. See Figure 8.

Preserving the integrity of the roof membrane is the

mostimportantroongconsideration.Ensurethatallroof

penetrations required to plumb and mount the solar collector

areproperlyashedandsealedinaccordancewithstandard
roongpractices.

If the region is subject to hurricane conditions, additional
steps may be required to secure the collector and mounting
hardware to the structural members. In certain areas of the
country, local building codes may require collector wind load

testingorprescribespecicmountingprocedures.Consult

your local building department.

Install the collectors as described in the Flat Roof Mounting
instructions.

FLAT ROOF MOUNTING

PREPARATION:

1. Determine the type of roof that the solar collector flat
roof mounting hardware is to be installed on.

2. Determine the roof construction, i.e.,

a. Roofing material over insulation, over steel deck
b. Roofing material over insulation, over wood deck
c. Roofing material over insulation, over concrete deck
d. Roofing material over wood deck only
e. Roofing material over concrete deck only
f. Roofing material over recovery board, insulation, and

wood, concrete, or metal

g. Other

3. Choose the appropriate fastener to work in conjunction
with the given roof construction. #14 x 3” Heavy Duty
Roof Fasteners have been included with this kit to cover
the majority of roof constructions. If a longer fastener is
required, use only OMG brand or equivalent. Be sure
the fasteners are long enough to penetrate the deck.
OMG Heavy Duty Roof Fasteners for concrete and
other decks will need to be determined by your installer
or architect. See Figure 7.

INSTALLATION INSTRUCTIONS

1. Locate the mounting points from Figures 1 & 2 and
Table 1 for vertical mount. Figures 3 & 4 and Table 2 for
horizontal mount. Layout the roof as specified.

2. Place the base plate on top of the finished roof (the base
plate is the flat metal piece with two threaded studs).
Align the base plate so that the studs are oriented in the
desired direction for application of the top plate.

3. Install the included #14 x 3” OMG Heavy Duty Roof
Fasteners or other suitable fasteners (dependent upon
the roofing material type) through the holes in the
perimeter of the base plate. See Figures 5 & 8.

4. Apply a generous amount of an approved roof sealant
around the base of the threaded rods.

5. Install a 10” x 10” target patch (patch material is to match
the roofing material installed on the roof) over the base
plate. Cut two small holes in the target patch so that when
it is installed it will fit tightly over the threaded studs and
be centered over the base plate. See Figure 6.

6. Apply target patch over the base plate using proper
mastic techniques so as to create a water tight patch.
This will vary dependent upon the type of roofing material.

7. The threaded studs should be the only part of the base
plate that is exposed. There may be bleed out of the
sealant applied around the studs. When the top plate is
installed this will help create a water tight compression
fitting. See Figure 5.

8. Install the top plate over the base plate threaded studs.
The top plate should be centered on the base plate when

installed properly. See Figure 5.

9. Install an EPDM bonded washer, stainless steel lock
washer, and hex nut over each stud and tighten. See
Figure 5.

10. Repeat steps as needed for the remainder of the
mounting bracket locations.
