4.5 Collector Plumbing
Rheem requires the use of all copper and brass ttings
in the collector loop plumbing. Couplings rather than
unions should be used to join the collectors to avoid
leaks and uid loss. Use only lead-free solder. Use

galvanized steel, CPVC, PVC, or any other type of
plastic pipe is prohibited.

dirt, grease, solder ux or other impurities that over
time affect the quality of the glycol HTF. A thorough
cleaning is required before charging the system with
glycol. Carefully review the cleaning procedures in
"Charging The System" outlined below.
All vertical piping between the storage tank and
the collector shall be supported at each story or at
maximum intervals of ten feet (10'). Copper plumbers
tape or tube strap is required. The pipe insulation
may not be compressed or crimped by the strapping
material.
The installation of all horizontal and vertical piping
may not reduce the performance or rating of any
structural member or re rated assembly. Adhere to all
