Installation - Solar Collectors; Regulations And Occupation Health And Safety (Oh&S); System Orientation And Inclination - Rinnai Prestige Operation & Installation Manual

REGULATIONS AND OCCUPATION HEALTH AND SAFETY (OH&S)
Installation and commissioning must be performed by authorised persons. Rinnai solar systems must be installed
in accordance with these instructions and all regulatory requirements which exist in your area including those in
relation to manual lifting, working at heights and on roofs. Applicable publications and regulations may include:
•
AS/NZS 5601 Gas Installations
•
AS/NZS 3500 National Plumbing and Drainage
•
AS/NZS 3000 Wiring rules
•
Building Codes of Australia
•
Local Occupational Health and Safety (OH&S) regulations
Solar collectors are heavy and bulky items and are usually positioned on the roofs of buildings. Each
Australian State and Territory has a principal Occupational Health and Safety (OH&S) Act which contains
requirements relating to the handling of large, bulky or awkward items and the prevention of falls from

elevated surfaces. Persons installing solar collectors must be aware of their responsibilities and be
adequately trained and qualified, in accordance with local OH&S requirements.

SYSTEM ORIENTATION AND INCLINATION

The performance of any solar hot water system is determined by the way that the system is installed. In Australia,
the solar collectors ideally should face the equator (North) as shown below. Where this orientation is not practical,
collectors facing within 45 degrees from North (between North-East and North-West) are acceptable and will only
reduce efficiency by approximately 5%.
The inclination of the solar collectors should ideally be the same as the latitude angle of the site. Inclinations within
20 degrees of the latitude angle of the site will only reduce efficiency by approximately 5%. Most roofs within
Australia have a slope of between 20° and 25° and provide an appropriately angled mounting surface.
Installers must ensure they comply with relevant local regulations in regards to inclination and orientation.
