INSTALLATION INFORMATION
ROOF MOUNTING OPTIONS
For roofs with a slope of 10° or less a flat roof frame must be used.
Roof construction must be checked to ensure that the roof timbers are capable of supporting the additional load.
(Refer to AS 3500.4 Appendix H).
The roof mounting option must be appropriate for the wind loading that is likely in the installed location. See the
section 'Mounting Location Suitability' on page 6.
For buildings higher than 10 metres the specifications for securing solar collectors to the building structure need
to be determined on a case by case basis for each building by a person qualified to do so in accordance with the
Building Code of Australia (BCA). Such specifications relate to the type of fastenings, the number of fastenings and
their embedment into the building structure. They are determined from factors including the geographical location
and topography, the prevailing wind conditions, building dimensions, rooftop form and structural materials, and
the intended location of the solar panels relative to building internal, edge and corner zones. The BCA references
AS1170.2 "Structural Design Actions Part 2: Wind Actions", AS3600 "Concrete Structures" and AS4100 "Steel
Structures" in relation to these specifications.
A solution may be provided using either kit DDHRKIT2 (2 collector) or DDHRKIT3 (3 collector), in accordance with
the instructions in the Rinnai document "High Rise Roof Mounting Frame Installation Instructions (Part Number
15401103)
