Rheem 12104793 Installation Instructions Manual page 23

11. Sensor Connector: Fit a sensor connector (4) (with hot sensor port) to the
outlet of the solar collector array.
Note: If the installation is on a tiled roof, the orientation of the hot sensor
port and hot sensor probe (when installed) must be angled between the
perpendicular (90°) to the roof to a maximum 30° off perpendicular down the
roof. Refer to
"Coupling Cold and Hot Pipes to Collector – Conetite Fittings"
Refer to
page 31.
12. End Plug (Collector Bung): Fit the end plugs (5) (collector bung)
assemblies to the two remaining solar collector connections.
"End Plug (Collector Bung) Assembly – Conetite Fittings"
Refer to
page 29.
13. Solar Hot and Solar Cold Pipes: Install the solar cold pipe from the solar
storage tank to the solar collectors (17) and the solar hot pipe from the solar
collectors (17) to the solar storage tank.
The solar hot and solar cold pipes should be a minimum DN15, but sized to
suit the installation for an open circuit system. Refer to
page 13.
The solar hot and solar cold pipes must have a continuous fall from the solar
collectors to the solar storage tank. Horizontal runs of pipe work are
acceptable and may be installed for an open circuit system.
The full length of the solar hot and solar cold pipes must be insulated. The
insulation must be capable of withstanding the temperatures generated by
the solar collectors under stagnation conditions.
Warning: Plumber – Be Aware: It is important you refer to
Plumber – Be Aware"
relating to the installation of the solar hot and solar cold pipes.
Refer also to
Work Roughing In Dimensions"
Notes:

Penetrations through the roofing material must be:
■
at the high point of the roof tile or metal sheet
■
made neatly and kept as small as practicable
■
waterproofed upon installation of the solar hot and solar cold
pipes.

Exposed insulated pipe work between the solar collectors and the
penetration through the roofing material should be kept to a minimum
to maintain the aesthetics of the installation.
