Mounting

The tank is a passive storage vessel (no internal heating element). Therefore, there is no required:

• Pedestal
• Flue, or
• Condensing section

Note

NOTE: Min. 1” high-density insulation below the tank is required (see Insulation section) for good system performance

Note

NOTE: It is required to wrap R6, or greater, insulation (see Insulation section) around the tank. It is easiest to do this prior to plumbing it.
