In order to completely protect the integrity of the solar collector and piping, the system is designed to be drained manually if subject to extended periods of disuse or persistent hard freeze conditions below minus 30° Fahrenheit. (See Sections 8.1 and 8.2 below).
3)INSTALLATION REQUIREMENTS - GENERAL
3.1The contractor shall obtain all required permits and approvals.
3.2The installation shall conform to all federal, state and local regulations, codes, ordinances and standards governing solar water heating system installations, and the contractor shall adhere to sound building safety and trade practices. Special consideration must be given to building code requirements for
the penetration of structural members and fire rated assemblies.
3.3The solar collector must be located in a structurally sound area of the roof that will be unshaded for the majority of the day all year round. Adjacent buildings and trees should be checked for possible winter shading. An instrument such as the
Pathfinder can be used for solar site analysis.
3.4Before the installation the contractor shall inspect the condition of the roof and notify the homeowner of any existing roof damage or necessary repairs.
3.5The homeowner and contractor shall confirm the location of all roof and ground mounted components in advance of the installation.
