TO WHOM IT MAY CONCERN:
The new Raypak series RP2100 pool heaters have been designed to eliminate the need for conventional heat sinks (high temperature piping). The initial connection to the heater is made with a 2" PVC union adapter to which PVC may then be connected with appropriate cement.
This newly authorized piping arrangement is described in the installation manual provided by Raypak, and has been successfully tested by Raypak to assure its acceptability.
