INSTALLATION DIAGRAMS-TOP INLET/OUTLET USAGE
GENERAL
The type, size and location of the relief valves must be in accordance with local codes. The locations of the relief valves shown in the installation diagrams are typical. The heater has a factory installed high temperature limit switch and temperature and pressure relief valve.
Cold water lines to heater should be installed as shown in order to minimize gravity circulation of hot water to building cold water lines.
A listed temperature and pressure relief valve of adequate capacity is installed on the heater. The locations shown in the installation diagrams on the following pages are typical.
The discharge opening of the temperature and pressure relief valve, located in front of the heater must be piped to an open drain and should not be subject to freezing temperatures.
Install in accordance with all local codes.
Use of the top inlet water connection requires installation of an inlet dip tube (refer to figure 8). The tube is supplied in the heater. Follow caution labels if applying heat to this fitting. Do not allow pipe dope to contact the plastic tube during installation.
CODE RESTRICTIONS
Use of the top inlet water connection is not permitted on installations in the state of North Carolina, due to the material of the tube (Polypropylene). Where such code restrictions exist, use only lower inlet tank connection. This may also require a heat trap - check local codes. The “Top Outlet” connection may still be used on these applications. Plug or cap all unused openings in the tank before filling with water.
DANGER
TEMPERATURE SETTING SHOULD NOT EXCEED SAFE USE TEMPERATURE AT FIXTURES. SEE WATER TEMPERATURE CONTROL WARNING ON PAGE 25. IF HIGHER PREHEAT TEMPERATURES ARE NECESSARY TO OBTAIN ADEQUATE BOOSTER OUTPUT, ADD AN
WATER SUPPLIED TO FIXTURES.
