American Water Heater 318281-000 Collector Piping, Multiple Panel, Outlet, 1” Copper

COLLECTOR PIPING

The piping of the system should be considered before a final decision is made on how the collectors are mounted. Piping should be made of copper tube of the type meeting local codes, insulated with Armacell UT Solaflex or similar. The maximum total piping length allowed in this system is 200 equivalent ft.

Use only lead-free solder. Use of 50/50 lead solder is expressly prohibited. Use of galvanized steel, CPVC, PVC, PEX or any other type of plastic pipe is prohibited.

Care should be taken in the spacing of collectors as attachment of piping is easiest with properly aligned collectors. The connection between the collector panels is made with copper unions. To aid in installation the collector array layout should be planned on the ground and the unions soldered to the adjoining headers prior to lifting the collectors to the roof. Similarly the top and bottom outside header that will not be used for the inlet or outlet (should be on opposite sides) should be capped with the 1” copper cap provided while on the ground. (See Figure 18 for details.)
