General:
All units are certified at 300 PSI (2068 kPa) test pressure and 150 PSI (1034 kPa) working pressure. Potable water connections are 3/4" (19mm) NPT on 8"
(203mm) centers. The 120 gallon model has 1" (25mm) NPT potable water connections on 8" (203 mm) centers.
Dimensions and specifications subject to change without notice in accordance with our policy of continuous product improvement.
Suitable for Water (Potable) Heating and Space Heating.
Toxic chemicals, such as those used for boiler treatment, shall NEVER be introduced into the potable side of this system. The potable side may NEVER be
connected to any existing heating system or component(s) previously used with a non-potable water heating appliance. The heat exchanger side of the unit
may be used in space heating applications.
Based on 200°F boiler water temperature and 50°F
potable water inlet.
