The temperature may be adjusted from 80°F/27°C to 180°F/82°C. Valves for reducing point-of-use temperature by mixing cold and The thermostat was adjusted to 120°F/49°C before the heater was hot water are available (see Figure 2). Also available are shipped from the factory. It is recommended that lower water inexpensive devices that attach to faucets to limit hot water temperatures be used to avoid the risk of scalding.

THE HEATER SHALL BE LOCATED OR PROTECTED SO IT IS CIRCULATING PUMP NOT SUBJECT TO PHYSICAL DAMAGE BY A MOVING VEHICLE. A circulating pump is used when a system requires a circulating loop or there is a storage tank used in conjunction with the heater. DO NOT LOCATE THE HEATER WHERE NOISE FROM THE Refer to the piping diagrams at rear of manual for electrical hookup EXHAUST OR INTAKE WILL BE OBJECTIONABLE.

MANIFOLD KITS Precision cut type “L” all copper State manifold kits assure water flow balance of all units. Without this balance, the full water heating and storage potential of the system cannot be achieved. Plus, the units with the higher water flow may have a shortened life. Unions shown in piping diagrams are not included in the manifold kits.
