Note:
1. First Hour Rating is the sum of the First Draw and Continuous Draw Ratings.
2. Ratings based on 77°F DHW temperature rise (135°F outlet temperature) and 180°F boiler supply temperature.
The ratings were obtained at the heat source (boiler) output rates and heat source flow rates shown. Other results
will be obtained under different conditions.
