Ratings based on 77F DHW temperature rise (135F outlet temp) and 180F boiler supply temperature. The ratings were obtained at the heat
source (boiler) output rates and heat source flow rates shown. Other results shall be obtained under different conditions.
Pressure Ratings: Maximum Allowable Tank Working Pressure - 150 psi. Design Hydrostatically Tested to 300 psi.

*First Draw Rating is the amount of stored water available from a fully recovered water heater, with no boiler output during the draw,
before the outlet temperature falls by 25F. At draw rates higher than that shown in First Draw Rating chart, less stored hot water may
be available.
