any discharge from the valve will exit only within 6 inches above, or at any distance below the structural floor and cannot contact any live electrical parts. The discharge opening must not be blocked or reduced in size under any circumstances. q CAUTION: A relief valve is designed to discharge excessively hot water. THE CUSTOMER IS RESPONSIBLE TO PROTECT PROPERTY AND PERSONNEL FROM HARM WHEN THE VALVE FUNCTIONS.
G. BOILER SUPPLY CONNECTIONS q WARNING: Boiler temperature must be controlled by the boiler high limit not to exceed 200°. Failure to do so will create a hazardous installation and void the applicable limited warranties. q All water supply fittings on this heater are brass – do not over tighten or strip threads. q It is recommended to use a union as per Figures 1 and 2. q Connect the supply line (from the boiler) to the “Hx In” fittings of the heat exchanger.
q TPI Wiring will vary depending on the type of boiler and valve controls in the system. Consult attached Wiring Diagrams for appropriate wiring configuration for your system. q CAUTION: If sensor is soldered directly to TPI, DO NOT BLEND SHARPLY OR OVERWORK. K.
