T/P VALVE Unlike other tank water heaters, the water in the tank of the Essency EXR is at atmospheric pressure. Per its construction, UL has evaluated that this water heater does not need a T/P valve. However please refer to your local codes for specific local requirements (See Recirculation Section for exceptions page 16).
Page 16
If you don’t have another way of confirming flow rate delivered by the recirculation pump, the EXR’s touchscreen does have the capability of displaying real-time flow rate by following the instructions in the Useful tips section (see page 38).
Page 17
In addition to the guidelines above, installers must follow all applicable codes and recirculation pump manufacturer instructions. For the unit to refill properly and to avoid unwanted alarms, the recirculation pump must be programmed to shut off at least once per day. Recirculation pumps designed for systems without a dedicated return line typically generate lower flow rates.
Page 18
3. ELECTRICAL CONNECTION We require that you contact a fully licensed plumbing or electrical professional for the electrical installation of the water heater. A separate branch circuit with copper conductors, overcurrent protective device and suitable disconnecting means must be provided by a qualified electrician. All wiring must conform to local codes or latest edition of National Electrical Code ANSI/NFPA 70.
